The issue in this case is whether a plaintiff who enters into an agreement and has marked as satisfied a judgment against one tortfeasor is barred from maintaining a second action against two other alleged tortfeasors for the same harm. The Court of Special Appeals held, inter alia, in Mathews v. Underwood-Gary, 133 Md.App. 570, 758 A.2d 1019 (2000), that petitioner could not maintain the second action on the ground that it was barred by the one satisfaction rule. We agree and shall affirm.

This appeal arises out of a medical malpractice action filed in the Circuit Court for Prince George’s County, in which Rita Underwood-Gary, petitioner, alleged that George J. Mathews, M.D. and Shaheer Yousaf, M.D., respondents, performed unnecessary surgery upon her. Approximately one *663week after entry of satisfaction of a money judgment1 in a 1992 lawsuit stemming from an automobile accident in the Circuit Court for Charles County (the “Thompson litigation”), petitioner filed this malpractice action in the Circuit Court for Prince George’s County. In this case, we shall hold that the satisfaction2 of the Thompson litigation judgment precluded petitioner from pursuing claims against George J. Mathews, M.D. and Shaheer Yousaf, M.D., her treating physicians, in the subsequent medical malpractice action.

On July 10, 1991, Rita Underwood-Gary and Ms. Marie Thompson were involved in an automobile accident in Charles County, Maryland. Following the accident, petitioner developed severe pain in her lower back and, in August 1991, she began receiving treatment from Dr. Shaheer Yousaf, an orthopedic surgeon. Dr. Yousaf treated petitioner over a period of approximately seven months. The treatment did not relieve petitioner’s back pain, and Dr. Yousaf concluded that petitioner suffered from an injury to the soft tissue in her back and an injury to the facet joint of the lower back. Dr. Yousaf indicated that surgery might be necessary to relieve petitioner’s pain. He referred her, for a second opinion, to Dr. George J. Mathews, a neurosurgeon. After Dr. Mathews met with petitioner and reviewed her previous medical treatment, he concurred with Dr. Yousafs diagnosis of petitioner’s injuries and recommended back surgery. On May 20, 1992, Drs. Yousaf and Mathews, along with Dr. Dadgar, a thoracic and vascular surgeon, performed back surgery on petitioner.

*664On July 22, 1992, petitioner filed a complaint sounding in negligence in the Circuit Court for Charles County against Ms. Thompson, the driver of the vehicle that collided with her on July 10, 1991, seeking recovery for the injuries allegedly suffered as a result of the automobile accident. In her complaint, petitioner alleged that Ms. Thompson negligently operated her vehicle and caused the collision. Petitioner further alleged that, as a result of the accident,

“[She had] sustained serious, painful and permanent injuries in and about her entire body, including but not limited to her head, back, hip, neck and other parts of her body; that the Plaintiff, Rita Lee Underwood, has suffered and will in the future suffer great physical pain, mental anguish and nervous shock; that the Plaintiff, Rita Lee Underwood, has in the past and will in the future be required to expend large sums of money for hospital, rehabilitation, medical and nursing care, treatment and related items.”

Petitioner also claimed damages for loss of enjoyment of life, loss of income, and loss of earning power. Petitioner requested the Charles County jury to award her damages for her back surgery. Significantly, during pre-trial discovery, petitioner was placed on notice that Thompson’s defense included the contention that the back surgery was unnecessary. At the latest, petitioner was on notice of the unnecessary surgery defense as of October 18, 1993, when she took the de bene esse deposition of Dr. Kevin Hanley, a defense witness. Respondent contends that Ms. Underwood-Gary knew of the unnecessary surgery defense long before this date, through Ms. Thompson’s Answer to the Complaint, discovery responses, and discovery depositions, all of which predated Dr. Hanley’s deposition by some time.

On October 27, 1993, the Thompson case proceeded to trial before a jury. Petitioner testified as to her entire course of therapy and treatment following the automobile accident. She offered into evidence all of the medical bills related to her treatment by Drs. Yousaf and Mathews, including the bills for the surgery and the hospital stay. She claimed a total of $38,195.28 in medical expenses, including all of the medical *665expenses related to the back surgery, as well as $250,000.00 for pain and suffering. Additionally, petitioner testified to the pain and physical limitations she experienced both before and after the surgery. She presented evidence that, as a result of the accident, and after the surgery, she was 30 percent permanently disabled. She described her three month recovery at a relative’s house, having to miss two to three weeks of work, and her inability to sit for long periods of time. Petitioner testified to the financial strain that the injury placed on her marriage, the constant pain that she felt in her lower back, and that she could no longer participate in activities that she used to enjoy, such as bowling and walking.

During her case-in-chief in the Thompson litigation, petitioner called Drs. Yousaf and Mathews as witnesses to testify on her behalf. In addition to eliciting testimony about the nature of the surgery, petitioner’s counsel inquired of Dr. Yousaf as to the necessity of the surgery:

“Q: Now, Doctor, I want to show you, Doctor, let me ask you this, do you have an opinion based on medical probability, the operation you performed in and assisted in was necessary to have in her case?

A: Based on indications.”

Petitioner also called Dr. Mathews, who testified that petitioner’s back surgery was related to the Thompson accident.3 Consistent with the pre-trial discovery, Thompson presented evidence in defense that petitioner suffered from a soft tissue injury, not a facet joint injury, and that the back surgery performed by Drs. Mathews and Yousaf was not necessary.

The jury found Ms. Thompson negligent, that petitioner had suffered injuries as a result of the accident, and awarded petitioner damages in the amount of $8,337.00 for medical expenses, $750.00 for lost wages, and $0 for pain and suffer*666ing.4 Judgment was entered in favor of petitioner for $9,087.00. Petitioner noted an appeal to the Court of Special Appeals, and while the appeal was pending, the parties settled the case for the policy limit of $20,000.00. The appeal was dismissed and an order of satisfaction was entered in the Circuit Court on May 15,1993.5

Approximately one week after the court entered the order of satisfaction in the Thompson litigation, petitioner filed suit against Drs. Yousaf and Mathews, alleging in her complaint that the doctors were negligent in that petitioner did not have any of the accepted indications for surgery and that the lumbar fusion was unnecessary. Petitioner sought recovery for her medical bills, lost wages, and pain and suffering.

Prior to trial, Drs. Yousaf and Mathews filed motions for summary judgment, arguing that petitioner’s action was barred by the doctrines of judicial estoppel, collateral estoppel, and satisfaction. The Circuit Court for Prince George’s County denied the motions. At trial, petitioner offered evidence that respondents failed to meet the standard of care with regard to the decision to operate and that the surgery was unnecessary. Respondents defended on the ground that the surgery was necessary. The trial court instructed the jury that the “only issue in the case is whether the surgical treatment was negligent or not.” Petitioner’s counsel argued to the jury that petitioner’s pain “is caused by a totally completely unnecessary operation and that it didn’t have to happen, but it did.”

The jury returned a verdict in petitioner’s favor in the amount of $437,073.69. The Circuit Court denied respondents’ *667post-trial motions and respondents then filed a timely appeal to the Court of Special Appeals. That court reversed the judgment on the grounds that the claim was barred by the doctrine of judicial estoppel and the one satisfaction rule. See Mathews v. Underwood-Gary, 133 Md.App. 570, 758 A.2d 1019 (2000). This Court granted Underwood-Gary’s petition for writ of certiorari. Underwood-Gary v. Mathews, 362 Md. 187, 763 A.2d 734 (2000).

The Court of Special Appeals held that the Circuit Court erred in rejecting the doctors’ argument that petitioner’s claim for all her damages had been satisfied in the Thompson litigation. See 133 Md.App. at 581, 758 A.2d at 1024. We agree. We shall affirm the judgment of the Court of Special Appeals on the ground that petitioner’s claim has been satisfied by the settlement in the Thompson litigation and shall not reach the court’s alternative holding that the action is barred by the doctrine of judicial estoppel.6

We begin with the general principle that a plaintiff is entitled to but one compensation for her loss and that satisfaction of her claim prevents further action against another for the same damages. See Welsh v. Gerber Products, Inc., 315 Md. 510, 524, 555 A.2d 486, 493 (1989); Morgan v. Cohen, 309 Md. 304, 312, 523 A.2d 1003, 1006 (1987); see also Knutsen v. Brown, 96 N.J.Super. 229, 232 A.2d 833, 836 (1967); Turner v. Pickens, 711 So.2d 891, 893 (Miss. 1998). This rule is equitable in nature and the purpose of the rule is to prevent double recovery and, thus, unjust enrichment. See Morgan, 309 Md. at 312, 523 A.2d at 1006; Lanasa v. Beggs, 159 Md. 311, 320, 151 A. 21, 25 (1930) (noting that “[i]t is neither just nor lawful *668that there should be more than one satisfaction for the same injury, whether that injury be done by one or more.”), rev’d on other grounds, Morgan, 309 Md. 304, 523 A.2d 1003; Sacchetti v. Springer, 303 Mass. 480, 22 N.E.2d 42 (1939); Vaca v. Whitaker, 86 N.M. 79, 519 P.2d 315, 319 (1974); see also Prosser and Keeton on Torts, § 48, at 330 (W. Page Keeton et al. eds., 5th ed. 1984).

Petitioner argues that the Court of Special Appeals erred in holding that her claim was satisfied because the court ignored the fact that Ms. Thompson and Drs. Yousaf and Mathews were not joint tortfeasors and that there was a separate and distinct injury caused by the medical malpractice of the doctors. She argues that not only was the back surgery unnecessary, but that the surgery caused an additional 20 percent whole body permanent impairment rating. Petitioner concludes that because no party has asserted that respondents are joint tortfeasors, the doctrine of satisfaction should not apply to a non-party.

Petitioner ignores the well-settled principle of tort law that “a negligent actor is liable not only for harm that he directly causes but also for any additional harm resulting from normal efforts of third persons in rendering aid, irrespective of whether such acts are done in a proper or a negligent manner.” Morgan, 309 Md. at 310, 523 A.2d at 1005-6. See also Restatement (Second) Of Torts § 457 cmt. c, illus. 1 (1965) (noting that original tortfeasor is liable for additional harm caused by a treating physician’s improper diagnosis and unnecessary surgery). This rule is based on the premise that the negligent actor, by his or her conduct, has placed the plaintiff in a position of danger and should answer for the risks inherent in treatment and rendering aid. See Morgan, 309 Md. at 310, 523 A.2d at 1006. At the same time, when a physician negligently treats the plaintiffs injuries, the physician becomes liable to the plaintiff to the extent of the harm caused by the physician’s negligence. See id. Thus, the physician’s negligent treatment is a subsequent tort for which *669both the doctor and the original tortfeasor are jointly liable. See id.

As we have indicated, a plaintiff is entitled to but one compensation for his or her loss, and full satisfaction of a plaintiffs claim prevents it from being further pursued. Thus, while multiple tortfeasors may be jointly and severally liable for the same injury, when payment of a judgment in full is made by one tortfeasor, “there is no doubt that the plaintiff is barred from a further action against another who is liable for the same damages.... ” Prosser and Keeton on Torts, § 48, at 331. Thus, double recovery for the same harm is not permissible. See Morgan, 309 Md. at 320, 523 A.2d at 1011.

While this principle appears straightforward, its application has led to confusion in the law. As we discussed in Morgan, much of the confusion resulted from the failure of courts to distinguish between jointly liable concurrent or successive tortfeasors on the one hand and true joint tortfeasors as they existed at common law, as well as the procedural rules that accompanied them.7 See Morgan, 309 Md. at 311, 523 A.2d at 1006. Courts also failed to distinguish between the conceptually related yet distinct concepts of a release of a claim and satisfaction of claim.8 See id. at 314-15, 523 A.2d at *6701008. In Morgan, we clarified these distinctions and overruled our previous case law that held that a release of the original wrongdoer as a matter of law released a negligently treating physician. See id. at 320, 523 A.2d at 1011 (overruling Lanasa v. Beggs, 159 Md. 311, 151 A. 21 (1930), and inconsistent portions of Cox v. Md. Elec. Rys. Co., 126 Md. 300, 95 A. 43 (1915)). Morgan went on to hold that the effect of a release on a subsequent action against a concurrent or successive tortfeasor is a question of fact to be determined by the language in the release itself, not as a matter of law. See id. at 316, 523 A.2d at 1008-09. Significantly, we extended this rationale to determining the effect of a consent judgment and a subsequent order of satisfaction.9 In so doing, we stated:

*671“If releases given under the circumstances of these cases do not, as a matter of law, bar action against one in Dr. Cohen’s position, it follows that the satisfaction of a judgment against Jones, the original tortfeasor, in an action to which Dr. Cohen was not a party, should have no greater effect. The policy implicated here is that against double *672recovery for the same harm, and it underlies the decisions in cases like Grantham, 251 Md. 28, 246 A.2d 548, (1968) Trieschman, 224 Md. 111, 166 A.2d 892 (1961) Lanasa, 159 Md. 311, 151 A. 21 and Cox. See also Huff v. Harbaugh, 49 Md.App. 661, 670, 435 A.2d 108, 113 (1981). But the policy against double recovery does not apply when a judgment against the original tortfeasor for the.original tort only has been satisfied, at least when the subsequent tortfeasor has not been joined in that suit. See Restatement (Second) of Judgments § 50 (1982). Like the question of intent with respect to the ambiguous releases, we are presented with a question of fact: Did the satisfied judgment include damages for both torts, or just the original tort? If the judgment in fact encompassed the former, HovermilTs claim against Dr. Cohen is barred because she has received full compensation for all her injuries; if it encompassed only the latter, her claim is not barred because she has been compensated only for the initial harm caused by Jones. This is a question of fact for the trial court.”

309 Md. at 320-21, 523 A.2d at 1011.

It is ordinarily a question of fact whether the judgment in the first action encompassed all the injuries sustained by the plaintiff and included those alleged in the second action to be attributable to the doctor’s alleged malpractice. As several of our sister states have recognized, however, although the scope of the satisfied judgment appears to be a question of fact, where, as here, the satisfaction of judgment follows a full trial of the merits, the issue is properly decided by the trial court on a motion for summary judgment. See, e.g., Williams v. Woodman, 424 So.2d 611, 614-15 (Ala. 1982); Cimino v. Alway, 18 Ariz.App. 271, 501 P.2d 447, 453 (1972); Knutsen v. Brown, 96 N.J.Super. 229, 232 A.2d 833, 837 (1967); Vaca v. Whitaker, 86 N.M. 79, 519 P.2d 315, 320 (1974). As the court in Knutsen stated:

“That issue is not to be resolved, as the opinion below directs, by having the jury in the malpractice case evaluate all plaintiffs ‘injuries and damages caused by all the tortfea-sors’ and comparing its evaluation with the $ 17,000 award*673ed by the jury in the automobile accident case. Such a comparison would be of no legal significance. The very nature of the process of admeasuring damages for personal injuries results in different juries reaching different results in evaluating the same injuries.

The injuries for which plaintiff seeks recovery in the malpractice case are those set forth in plaintiffs answers to interrogatories and in the pretrial order. The injuries for which plaintiff recovered damages in the automobile accident case are to be ascertained by the court from an examination of the pertinent portions of the record in that case. Such portions of the record may include plaintiffs answers to interrogatories, the pretrial order, the testimony, the charge of the court and the opening and closing statements of counsel.

The procedure to be followed is analogous to that used in deciding a plea of collateral estoppel in order to ascertain whether or not the issues sought to be presented in the instant case were presented at the former trial.

Since resolution of the posed question involves a study and comparison of the records in the two cases, the issue is to be tried by the court, not by the jury. The issue should be disposed of before trial of the merits of the malpractice action and may properly be decided upon a motion for summary judgment.”

Knutsen, 232 A.2d at 836-37 (citations omitted).

We agree with the rationale set forth by the court in Knutsen. The preclusive effect of a satisfied judgment in a prior case is properly a question for the trial judge, not the jury.

A review of the provided portions of the trial record from the Thompson litigation demonstrates that the satisfied judgment in the Thompson litigation embodies an evaluation as to all of the harms that Petitioner later claimed in the malpractice action.10 Petitioner sought to recover the same *674post-surgery medical expenses that she presented to the jury in the Thompson litigation, including the Yousaf and Mathews medical bills, hospital bills, and other bills related to postoperative treatment. Petitioner also sought recovery for the same pain and suffering. In both cases, petitioner presented evidence of her fifty years life expectancy and requested the jury to compensate her for future pain and physical limitations that accompanied her back injury. Petitioner also argued to both juries that, after the surgery, she was approximately 30 percent permanently disabled. In the medical malpractice action, she presented evidence that approximately 20 percent of her permanent disability was attributable to the unnecessary surgery. The surgery may have contributed to the severity of petitioner’s permanent disability, but, in the Thompson litigation, petitioner specifically sought to recover damages for the entire 30 percent disability. The jury evaluated her claim and awarded damages for the full 30 percent permanent disability. All of the harm claimed in the present case was included among the harms alleged to have resulted from the negligence in the Thompson litigation. The Thompson jury evaluated all of the claims and determined their worth in a verdict that was embodied in a judgment and marked satisfied. That judgment now precludes relitigating the value of the claims actually litigated. Therefore, all of Petitioner’s claimed damages have been satisfied.

Chief Judge Murphy, writing for the Court of Special Appeals, observed that

“[wjhile the amount of the auto negligence settlement may not have been ‘satisfactory’ to appellee, when the damage claim that she had been asserting was ‘satisfied’ as a matter *675of law, she was thereafter prohibited from recovering more funds for the same injuries. Having filed an order of satisfaction in the (auto negligence) Charles County case, appellee could not thereafter assert an ‘unnecessary surgery’ claim in the Circuit Court for Prince George’s County.”

Mathews v. Gary, 138 Md.App. at 583, 758 A.2d at 1025. We agree. In the Thompson litigation, plaintiff presented evidence of all of her injuries arising from the accident and from the surgery. Petitioner has identified no new and independent injury that was not presented to the Thompson jury. As such, there are no damages that remain to be recovered in the medical malpractice action.

JUDGMENT OF THE COURT OF SPECIAL APPEALS AFFIRMED. COSTS TO BE PAID BY PETITIONER.

Dissenting Opinion by BELL, C.J.

Dissenting.

A person who seeks advice and/or treatment from a professional is entitled to trust and rely upon that advice, care or treatment. Otherwise, that person will not have the trust and confidence so necessary for there to be the candor and openness that are likely to lead to adequate treatment or representation. This is just common sense. Thus, a rule that conditions the ability of a plaintiff in a tort action to recover for the negligence or malpractice of his or her expert witness, or treating physician, on that plaintiffs second-guessing, investigating, and, perhaps, suing, his or her witness or physician whenever the defense, buttressed by expert testimony of its own, challenges, as inadequate or just plain wrong, the plaintiff expert’s opinion or treatment, not only undermines the trust and confidence critical to the plaintiffs relationship with his or her witness, but may hamper and impede the ability of the plaintiff to present his or her case. Moreover, such a rule may, in effect, insulate the plaintiffs expert witness from liability for his or her negligence. Because this is the proba*676ble effect of the majority’s holding in this case, see 366 Md. 660, 675, 785 A.2d 708, 717, supra, I dissent.

The petitioner was injured in an automobile accident, as a result of which she sought and received treatment from the respondents, Dr. Yousaf and Dr. Mathews. Drs. Yousaf and Mathews diagnosed the petitioner’s injuries as an injury to the soft tissue in her back and to the facet joint. They recommended and, when the petitioner agreed, they performed, surgery for the facet joint injury.

In her suit against Thompson, the other party to the accident in which she was involved and whose negligence she claimed caused her injuries (the automobile accident case or the Thompson litigation), the petitioner claimed $38,195.28 in medical expenses and $250,000 in pain and suffering. That action included a claim for damages resulting from her back surgery, a claim that the defendant disputed and, indeed, alleged was unnecessary.. The Court of Special Appeals suggests that this latter allegation, or at least it and subsequent deposition testimony of defense witnesses, should have been sufficient notice to the petitioner that Dr. Yousaf and Dr. Mathews may have been liable to her for the unnecessary surgery and, therefore, should have been joined as defendants. Mathews v. Gary, 133 Md.App. 570, 580, 758 A.2d 1019, 1024 (2000).

At trial, testifying for the petitioner, both Dr. Yousaf and Dr. Mathews stated that the petitioner’s back surgery was made necessary by the accident. As expected, and consistent with the defense raised, testimony was presented in the defense case that the petitioner suffered from only soft tissue injury as a result of the accident and the facet joint surgery was, in fact, not necessary. Although the jury returned a verdict in favor of the petitioner, it awarded her only $8,337.00 for medical expenses and $750.00 for lost wages. No award was made for pain and suffering. The verdict sheet submitted to the jury did not require the jury to decide and then specify whether the petitioner’s back surgery'was made necessary by the accident.

*677While the petitioner’s appeal was pending, the parties settled for the defendant’s policy limit, or $20,000.00. Consequently, the petitioner dismissed her appeal and entered an order of satisfaction in the Circuit Court.

Following the settlement, the petitioner brought an action against the respondents, alleging that the surgery they performed on her was unnecessary and, as a result, seeking recovery of her medical bills, lost wages and pain and suffering. She offered in support of her claim evidence, namely the deposition testimony of the defense expert who testified on the issue in the first trial that the respondents did not meet the standard of care in determining the necessity for the operation. Although the respondents defended on the merits, arguing as they did in the first trial, that they acted properly and out of necessity, they also maintained that the action was barred by, inter alia, satisfaction, that the petitioner had already received the one satisfaction to which she was entitled when she settled the Thompson litigation. The jury found for the petitioner and awarded her $437,073.69.

The Court of Special Appeals reversed, holding that both judicial estoppel, 133 Md.App. at 578-80, 758 A.2d at 1023-24, and the one satisfaction rule, id. at 580-83, 758 A.2d at 1024-25, barred the petitioner’s recovery. With regard to the latter, it was important to the intermediate appellate court that the petitioner chose to pursue damages for the back surgery despite being on notice that the defense claimed the surgery was not necessary. Id. at 581, 758 A.2d at 1025. Proceeding from this premise, relying on Morgan v. Cohen, 309 Md. 304, 523 A.2d 1003, (1987), it asserted, “[i]n this case, no reasonable trier of fact could find that appellee did not seek compensation for her surgery from the Charles County jury,” id. at 581, 758 A.2d at 1025, and then concluded, “the settlement of that case included ‘satisfaction’ for her bone fusion surgery.” Id. After discussing a Pennsylvania intermediate appellate court case, Brandt v. Eagle, 412 Pa.Super. 171, 602 A.2d 1364 (1992), the court held:

“We are persuaded that the order of satisfaction filed in her Charles County case precluded appell[ee] from thereafter *678obtaining an award of damages against appellants. While the amount of the auto negligence settlement may not have been ‘satisfactory’ to appellee, when the damage claim that she had been asserting was ‘satisfied’ as a matter of law, she was thereafter prohibited from recovering more funds for the same injuries. Having filed an order of satisfaction in the (auto negligence) Charles County ease, appellee could not thereafter assert an ‘unnecessary surgery’ claim in the Circuit Court for Prince George’s County.”

Id. at 583, 758 A.2d at 1025-26.

The majority in this Court affirms the Court of Special Appeals on the one satisfaction rule. 366 Md. 660, 662, 785 A.2d 708, 709 (2001). Noting the equitable nature of the rule and that its purpose is to prevent double recovery, id. at 667, 785 A.2d at 712, the majority points out that it follows from “the well-settled principle of tort law that ‘a negligent actor is liable not only for the harm that he directly causes but also for any additional harm resulting from the normal efforts of third persons in rendering aid, irrespective of whether such acts are done in a proper or a negligent manner.’ ” Id. at 668, 785 A.2d at 712-13 (quoting Morgan v. Cohen, supra, 309 Md. at 310, 523 A.2d at 1005). Thus, it concludes, a physician’s negligent treatment of injuries caused by a prior tortfeasor is a subsequent tort for which both the doctor and that tortfea-sor are hable. Id. at 670, 785 A.2d at 714.

The majority candidly admits that there is confusion in the law, attributing much of it to “the failure of courts to distinguish between jointly liable concurrent or successive tortfeasors on the one hand and true joint tortfeasors as they existed at common law, as well as the procedural rules that accompanied them.” 366 Md. at 669, 785 A.2d at 713 (footnote omitted). After explaining the distinction, see 366 Md. at 667 n. 6, 785 A.2d at 712 n. 6, the majority acknowledges another source of the confusion: the failure of courts “to distinguish between the conceptually related yet distinct concepts of a release of a claim and satisfaction of a claim.” Id. at 669, 785 A.2d at 713. Quoting Trieschman v. Eaton, 224 Md. 111, 116-*67917 n.4, 166 A.2d 892, 895 n. 4 (1961), in turn quoting Prosser, Torts § 46 at 243-44 (2d ed. 1955), the majority notes that “a satisfaction is an acceptance of full compensation for the injury; a release is a surrender of the cause of action, which may be gratuitous, or given for inadequate consideration,” id. at 669 n. 7, 785 A.2d at 713 n. 7, and concedes that the effect of the release or the satisfaction on a subsequent action against a concurrent or successive tortfeasor is a question of fact. Id. at 669, 785 A.2d at 713. It asserts, however, that “where ... the satisfaction of judgment follows a full trial of the merits, the issue is properly decided by the trial court on a motion for summary judgment .” Id. at 672, 785 A.2d at 715 (citing Williams v. Woodman, 424 So.2d 611, 615 (Ala. 1982); Cimino v. Alway, 18 Ariz.App. 271, 501 P.2d 447, 453 (1972); Knutsen v. Brown, 96 N.J.Super. 229, 232 A.2d 833, 837 (1967); Vaca v. Whitaker, 86 N.M. 79, 519 P.2d 315, 320 (1974)).

With regard to this case, the majority holds that the judgment entered in the automobile accident case was satisfied and that this satisfaction encompassed all of the damages that the petitioner sought in that case. Because the damages sought by the petitioner in this case, and which she recovered in the earlier case, are the same damages and giving effect to the one satisfaction rule’s policy against double recovery, the majority concludes, as a matter of law, presumably determining that no reasonable trier of fact could conclude otherwise, see Maryland Rule 2-501(e),1 that the petitioner’s action against the respondents was precluded. Its conclusion as to the identity of the damages in the two cases is based on its review of the trial record from the automobile accident case *680and its analysis of the evidence offered by the petitioner in that case and the one under review.

I have no quarrel with the principle that a plaintiff is entitled to but one compensation for loss and that satisfaction of a claim to recover that loss precludes further action, even against another for the same loss. Our cases are quite clear on this point.2 See Welsh v. Gerber Products, Inc., 315 Md. 510, 523-24, 555 A.2d 486, 493 (1989); Morgan v. Cohen, supra, 309 Md. at 312, 523 A.2d. at 1006; Lanasa v. Beggs, 159 Md. 311, 319, 151 A. 21, 25 (1930). Nor do I have a problem with the use of equitable principles to prevent double recovery, and thus, unjust enrichment. And I agree generally with the majority’s statement of the law: ordinarily a question of fact, when the judgment that is satisfied results from full adjudication, i.e., trial on the merits, its effect may be decided as a matter of law in the context of summary judgment. My dispute with the majority is quite basic and specific; I simply do not agree that, under the facts of this case, the scope of the judgment in the automobile accident case should have been, or could have been, determined as a matter of law.

To be sure, the judgment in favor of the petitioner was entered after a trial on the merits, at which the petitioner *681sought, presenting evidence in support, damages for the surgery she maintained was necessitated by the negligence of the defendant in the automobile accident case she claimed caused her injuries. It also is true that an order of satisfaction as to the judgment was entered in that case. But I also find it significant that the entry of the order of satisfaction postdated the settlement agreement that the parties to the first case entered into while the appeal of the Circuit Court judgment was pending.3 It is logical to assume that the dismissal of the appeal and the entry of satisfaction were terms of the settlement. It is, in addition, worthy of note that the evidence that the petitioner offered in support of her claim for compensation for her back surgery, was countered, and strenuously so, by evidence maintaining that the surgery was unnecessary. From the size of the verdict, given these conflicting arguments, it may fairly be argued that the jury may not have intended to, and, therefore, did not, compensate the petitioner for the surgery, accepting perhaps the defendant’s argument that the surgery was unnecessary.

Thus, this issue is not appropriately decided as a matter of law, on summary judgment. It is not at all clear, in short, that the parties intended the petitioner’s recovery to include compensation for the surgery performed by the respondents. There is, to the contrary, I submit, good reasons to suppose *682that they did not. Certainly, there was no incentive on the part of the defendant in that case to carry the respondents’ water, particularly since quite explicit, not just necessarily implicit, in the defense was the defendant’s insistence that the respondents were negligent and that she should not be made to be responsible for that negligence, by paying for it. Nor would it have been in the petitioner’s interest to agree to accept an amount she clearly viewed as insufficient recompense, in full satisfaction of all of her injuries, including those that she was advised by the respondents were the responsibility of the defendant in that case, but that, it appears, she had come to realize, as the defendant in the automobile accident case argued, really were the result of the respondents’ negligence and when she apparently intended to pursue an action to recover for the damages that negligence caused.

This case is quite different from those on which the majority bases its decision. In each of those cases, the plaintiff accepted the jury’s verdict; there were no appeal and subsequent settlement and, so far as the facts of those cases reveal, there was no dispute in the trial court as to the damages at issue on the appeal. In Williams v. Woodman, supra, the plaintiff having prevailed on the merits in an action involving the uninsured motorist provision in an insurance policy, withdrew from the court registry the moneys deposited by the insurance carrier. Similarly, in Knutsen v. Brown, supra, following a trial on the merits, judgment was entered for the plaintiffs, with which they were dissatisfied. Rather than appeal, however, they accepted the judgment after their motion to set the judgment aside as inadequate had been denied, and subsequently sued the treating physicians for malpractice.4 The *683plaintiffs in Vaca v. Whitaker, supra, obtained a judgment, after a trial on the merits in Federal court, in which the jury was instructed “to return a verdict in damages for the plaintiffs in this case, to the full extent of any injury you find was sustained as a result of the accident. Also, any injury you find was a proximate result of any negligence you might find on the part of Dr. 'Whitaker [sic] in treating Alicia Vaca.” Dr. Whitaker was the defendant in the subsequent litigation sounding in malpractice.

As the facts of this case reveal, this case really is not one decided on the merits for purposes of the application of the one satisfaction rule; rather, because it was settled before the appellate process concluded, it is more akin to a case in which a release is given or a judgment by consent is entered. In either event, as the majority recognizes, see 366 Md. at 669, 785 A.2d at 713 and n. 7; see also Morgan v. Cohen, supra, 309 Md. at 316, 523 A.2d. at 1008-09; Welsh v. Gerber Products, supra, 315 Md. at 512, 555 A.2d at 486 (specifically as to consent judgments), the decision as to the preclusive effect of releases and consent judgments is not one to be resolved as a matter of law.

In Welsh v. Gerber Products, we addressed “the scope and reach of nonmutual, defensive, collateral estoppel following the *684entry of a consent judgment in a joint tort-feasor situation.” 315 Md. at 512, 555 A.2d at 486. We concluded that, to find the answer to that question, a court had to “examine the consent judgment to determine whether it represented a determination of the complete equivalent of the plaintiffs damages.” Id. at 523, 555 A.2d at 492. We reasoned:

‘When an action for damages proceeds to trial and a judgment is entered on the verdict, that judgment represents a final determination of the plaintiffs claim for those damages. It is entirely appropriate to bind the plaintiff to that assessment of damages, directly and collaterally, even though the determination may be less than the plaintiff believes is fair, or may be thought to have been a result of jury compromise. If there is error in the award, relief must be sought by the appropriate post-trial motion. Once final, the judgment is properly given preclusive effect as to the issues actually litigated. But these principles do not necessarily apply to a consent judgment. The issue of full damages generally has not been litigated when a consent judgment is entered and, as we have previously pointed out, the parties may or may not agree that the amount being entered by consent represents the plaintiffs full claim for damages.”

Id. Thus, consideration of the actual intent of the parties is necessary.

The cases on which the majority relies stand for the essentially unremarkable proposition that the effect of a satisfaction of judgment entered following a full trial of the merits, because it “involves a study and comparison of the records in the two cases,” Knutsen v. Brown, supra, 232 A.2d at 837, although still a question of fact, may be determined on summary judgment, rather than at a trial. Id. at 837; see Williams v. Woodman, 424 So.2d at 612-13, 615; Vaca v. Whitaker, supra, 519 P.2d at 319; Cimino v. Alway, supra, 501 P.2d at 449-50. A State’s summary judgment principles consequently may need to be applied. Such principles may differ from State to State. See Vaca v. Whitaker, 519 P.2d at 319-20 (noting the difference between the summary judgment *685rules applicable in New Mexico and those applied in Arizona in Cimino v. Alway).

Thus, Maryland summary judgment practice is implicated. Recently, in Frederick Road Ltd. Partnership v. Brown & Sturm, 360 Md. 76, 93-94, 756 A.2d 963, 972-73 (2000), we stated, on the subject:

“Summary judgment practice in this state is governed by Maryland Rule 2-501. It states, in relevant part, ‘[t]he court shall enter judgment in favor of or against the moving party if the motion and response show that there is no genuine dispute as to any material fact and that the party in whose favor judgment is entered is entitled to summary judgment as a matter of law.’ Rule 2-501(e). Summary judgment is not a substitute for trial. Goodwich v. Sinai Hosp. of Baltimore, Inc., 343 Md. 185, 205, 680 A.2d 1067, 1077 (1996). The function of the trial court at the summary judgment stage is to determine whether there is a dispute as to a material fact sufficient to require an issue to be tried. Gross v. Sussex, Inc., 332 Md. 247, 255, 630 A.2d 1156, 1160 (1993); Foy v. Prudential Insurance Company of America et al., 316 Md. 418, 422, 559 A.2d 371, 373 (1989); Coffey v. Derby Steel Company, 291 Md. 241, 247, 434 A.2d 564, 568 (1981). Thus, an appellate court’s review of the grant of summary judgment involves the determination whether a dispute of material fact exists, Gross, 332 Md. at 255, 630 A.2d at 1160; Beatty v. Trainmaster Products, 330 Md. 726, 737, 625 A.2d 1005, 1011 (1993),. and ‘whether the trial court was legally correct.’ Heat & Power Corporation v. Air Products & Chemicals, Inc., 320 Md. 584, 591, 578 A.2d 1202, 1206 (1990) (citations omitted). Evidentiary matters, credibility issues, and material facts which are in dispute cannot properly be disposed of by summary judgment. See Pittman v. Atlantic Realty Co., 359 Md. 513, 536, 754 A.2d 1030, 1042 (2000) (recognizing that ‘Maryland law ... has not viewed the function of summary judgment to be determining whether an issue is genuine based on credibility.’); Hartford Ins. Co. v. Manor Inn of Bethesda, Inc., 335 Md. 135, 144, 642 A.2d 219, 224 (1994); Merchants *686Mtg. Co. v. Lubow, 275 Md. 208, 217, 339 A.2d 664, 670 (1975).

Instead, a trial court reviewing a motion for summary-judgment must ask whether there exists a genuine dispute as to a material fact and, if not, what the ruling of law should be upon those undisputed facts. Brewer v. Mele, 267 Md. 437, 442, 298 A.2d 156, 160 (1972). If the facts are susceptible of more than one inference, the materiality of that arguable factual dispute must be judged by looking to the inferences that may be drawn in a light most favorable to the party against whom the motion is made and in the light least favorable to the movant. Id.; Dietz v. Moore, 277 Md. 1, 4-5, 351 A.2d 428, 431 (1976); Impala Platinum, Ltd. v. Impala Sales (U.S.A.), Inc., 283 Md. 296, 326, 389 A.2d 887, 904-905 (1978).”

We made these points most recently in Jones v. Mid-Atlantic Funding Co., 362 Md. 661, 675-76, 766 A.2d 617, 624-25 (2001).

In concluding that the satisfied judgment in the Thompson litigation included all of the damages claimed in the present case, the majority relies on the fact that the petitioner sought to recover in the former case some of the same damages she sought to recover in this case, i.e., the respondents’ medical bills and the same pain and suffering. It also was persuaded by the identity of the evidence in both cases as to the petitioner’s life expectancy and of her future pain and physical limitations accompanying the back injury. In addition, the majority asserts that she argued to both juries that she suffered a 30 percent permanent disability and that the jury awarded that level of disability in the automobile accident case.

Significantly, although acknowledging it in setting out the facts, the majority gives no weight to, and, indeed, does not mention in its discussion of the identity of issues, that the defendant in the automobile accident case disputed the necessity of the operation the respondents'performed even as the respondents were insisting that the operation was necessary, *687and that the petitioner only litigated the issue in response to the defense, all the while maintaining that the necessity of the operation was not relevant. Also not considered by the majority, or so it seems, is the significance of the award that the jury actually made. The jury awarded less than half of the medical expenses claimed — $8,337.00 of the $38,195.28 claimed, a sizable portion of which represented the respondents’ bill for medical services. The jury also awarded no pain and suffering damages. Knutsen points out that one of the critical inquiries to be made when determining the effect of a satisfied judgment is “whether the amount paid actually constituted full compensation for the total loss suffered by plaintiff as the result of the negligence of the original tortfeasors and the negligence of the doctors.” 232 A.2d at 836, citing Daily v. Somberg, 28 N.J. 372, 146 A.2d 676, 69 A.L.R.2d 1024 (1958). The majority also did not consider, although aware of the fact, having reported it in the facts, that the parties actually settled this case while the trial court judgment was pending appeal. These are matters that should have been considered and, had they been considered, would have demonstrated, as I have previously shown, see 366 Md. at 667, 785 A.2d at 712, supra, the existence of a genuine factual dispute, defeating summary judgment.5 The test is, as I have pointed out and the majori*688ty, by citing Morgan v. Cohen, supra, recognizes, whether the damages sought in the second action were compensated in the first:

“Like the question of intent with respect to the ambiguous releases, we are presented with a question of fact: Did the satisfied judgment include damages for both torts, or just the original tort?”

309 Md. at 321, 523 A.2d at 1011. Nevertheless, the majority seems to have adopted the intermediate appellate court’s formulation of the issue: whether a “reasonable trier of fact could find that appellee did not seek compensation for her surgery from the Charles County jury.” Mathews v. Gary, 133 Md.App. at 581, 758 A.2d at 1025.6

I am also concerned about the majority’s suggestion, and the more explicit one by the Court of Special Appeals,7 with regard to the importance of a defense argument, of which the plaintiff is put on notice, in determining the scope of the issues decided or the effect of a satisfied judgment on subsequent *689litigation. Equity is a two-way street. My concern is that the application of the one satisfaction rule in the case sub judice leads not to full satisfaction of the petitioner’s claim, but to non-satisfaction of that claim against a subsequent and distinct tortfeasor, upon whom the petitioner relied, as she had the right to do, and with whom the petitioner maintained a confidential and trusting relationship. The problem posed by the suggestion made by the intermediate appellate court and not repudiated by the majority, that a plaintiff must investigate, and perhaps pursue a claim against his or her experts or doctors whenever the charge is made that their advice and treatment is faulty, is that the plaintiff is forced to question “... a relationship built on trust and confidence [which] generally gives the confiding party the right to relax his or her guard and rely on the good faith of the other party so long as the relationship continues to exist,” Frederick Rd. Ltd. P’ship v. Brown & Sturm, 360 Md. at 97-98, 756 A.2d. at 974-7, when, ordinarily, “[t]he confiding party ... is under no duty to make inquiries about the quality or bona fides of the services received, unless and until something occurs to make him or her suspicious.” Id.8 Surely, a difference in opinion between expert witnesses articulated in the answer to a complaint or deposition testimony given prior to trial, or even trial testimony, does not necessarily rise to the level of “something suspicious,” which would cause a plaintiff to question the competency of those witnesses. Every difference of opinion does not lead to a finding of malpractice. Indeed, if a mere difference of opinion constitutes “notice” of not potential malpractice, but malpractice, plaintiffs will be hard pressed to get anyone, who may be charged in a malpractice action, to testify on their behalf.
