{¶ 1} In 1997, plaintiff-appellee Carolyn A. Vaught sought treatment at the Cleveland Clinic for chronic right-knee pain. Defendant-appellant Dr. Peter J. Brooks, an employee of defendant-appellant the Cleveland Clinic, was her assigned physician. After an initial examination and consultation, Dr. Brooks recommended total knee-replacement surgery to alleviate appellee’s pain and to improve function and mobility. On December 10, 1997, Dr. Brooks performed the surgery, which required that he implant a tibial base plate.
{¶ 2} After the surgery, appellee continued to experience pain in her right knee. She informed Dr. Brooks of the pain during postoperative appointments. According to him, appellee’s X-rays revealed that the pain was being caused by an overhang of the tibial base plate rubbing against appellee’s iliotibial band (tendons that run along the outside of the leg). Dr. Brooks concluded that this overhang was the source of appellee’s pain; thus, he recommended a second surgery in which he planned to cut a “window” in appellee’s tendons to eliminate the rubbing and pain.
{¶ 3} The second surgery was performed on April 15, 1998; the pain, however, continued and even increased in appellee’s right knee and in the area of the window surgery. Dr. Brooks recommended a third surgery to replace the tibial base plate with a smaller one, but appellee decided to obtain a second opinion.
{¶ 4} Appellee’s new physician agreed that a correctly sized plate would remedy her pain. On September 16, 1998, her new physician replaced the first plate. During the surgery, the physician saw the overhang and noted that the *486first plate had been positiohed incorrectly. After the surgery, appellee experienced pain relief in all areas of her right knee except where Dr. Brooks had performed the window surgery.
{¶ 5} Appellee filed suit against appellants, alleging medical malpractice. In appellee’s interrogatories, appellants were asked to “[ijdentify any and all expert witnesses you intend to call at the Trial of this matter including the specialty area and anticipated area or subject matter of the testimony.” Dr. Brooks responded, “Currently under consideration. This Answer will be amended as required by the Ohio Rules of Civil Procedure, Local Rules of Court or Court Order.” Dr. Brooks never supplemented his response.
{¶ 6} The court established a deadline for the parties to file expert reports, with which appellee complied. The Cleveland Clinic, however, asked for an extension, which the court granted. Neither appellant ever submitted an expert report. One week before trial, appellants filed a brief in which Dr. Brooks was listed as the treating physician and expert witness. Appellee filed a motion in limine to preclude Dr. Brooks from testifying as an expert witness because he had not complied with Loc.R. 21.1 of the Court of Common Pleas of Cuyahoga County, General Division. The court granted the motion. At the close of testimony, the jury returned a verdict in favor of appellee.
{¶ 7} On appeal, appellants argued that the trial court abused its discretion in not allowing Dr. Brooks to testify as an expert witness. The court of appeals disagreed and affirmed the decision of the trial court, reasoning:
{¶ 8} “[A] party who also seeks to testify as an expert witness must be identified as an expert witness prior to trial and comply with all relevant provisions of Loc.R. 21.1.
{¶ 9} “* * *
{¶ 10} “Our finding that [Dr. Brooks] had the duty seasonably to identify himself as an expert witness and that the court did not abuse its discretion by forbidding [Dr. Brooks] from testifying as an expert necessarily means that [Dr. Brooks’s] argument that the court erred by failing to grant a new trial must be rejected on the grounds that no error occurred below.”
{¶ 11} The cause is now before this court on the allowance of a discretionary appeal.
{¶ 12} The sole issue for determination by this court is whether the trial court abused its discretion in not allowing Dr. Brooks to testify as an expert witness in his own behalf, after he failed to file a written report and failed to supplement answers to interrogatories asking that expert witnesses be identified. Finding that there was no abuse of discretion, we affirm the judgment of the court of appeals.
*487{¶ 13} In Nakoff v. Fairview Gen. Hosp. (1996), 75 Ohio St.3d 254, 662 N.E.2d 1, syllabus, this court held: “A trial court has broad discretion when imposing discovery sanctions. A reviewing court shall review these rulings only for an abuse of discretion.” As such, in order to have an abuse of discretion, “the result must be so palpably and grossly violative of fact or logic that it evidences not the exercise of will but the perversity of will, not the exercise of judgment but the defiance of judgment, not the exercise of reason but instead passion or bias.” Id. at 254, 256, 662 N.E.2d 1, citing State v. Jenkins (1984), 15 Ohio St.3d 164, 222, 15 OBR 311, 473 N.E.2d 264. Accordingly, we must look at the language of the local rule that was in place at the time this suit was commenced to determine whether the trial court abused its discretion.
{¶ 14} Former Loc.R. 21.1 stated:
{¶ 15} “(B) A party may not call an expert witness to testify unless a written report has been procured from the witness and provided to opposing counsel. * * *
{¶ 16} “* * *
{¶ 17} “(C) All experts must submit reports. If a party is unable to obtain a written report from an expert, counsel for the party must demonstrate that a good faith effort was made to obtain the report * * *. In the event the expert witness is a treating physician, the Court shall have the discretion to determine whether the hospital and/or office records of that physician’s treatment which have been produced satisfy the requirements of a written report. The Court shall have the power to exclude testimony of the expert if good cause is not demonstrated.” (Emphasis added.)
{¶ 18} Furthermore, Civ.R. 26(E) provides:
{¶ 19} “Supplementation of responses. A party who has responded to a request for discovery with a response that was complete when made is under no duty to supplement his response to include information thereafter acquired, except as follows:
{¶ 20} “(1) A party is under a duty seasonably to supplement his response with respect to any question directly addressed to * * * (b) the identity of each person expected to be called as an expert witness at trial and the subject matter on which he is expected to testify.”
{¶ 21} Thus, the rules make clear that a party must make a good-faith effort to submit a written expert report once a court has established a deadline for filing expert witness reports. Even when the treating physician is the expert witness, former Loc.R. 21.1 clearly stated that a trial court has the option of accepting hospital or office records in lieu of an expert report, should that court *488determine that to do so would adequately provide the requesting party with the information that it needs.
{¶ 22} In the instant case, by requesting an extension, appellants led appellee and the trial court to believe that they would be filing an expert report. Once the extended deadline arrived, however, appellants did not submit a report. Instead, they notified the court and appellee in a brief, submitted one week before trial, that Dr. Brooks would be testifying as an expert witness. Moreover, during the entire discovery phase of the proceedings, appellants did not identify Dr. Brooks as the expert witness; thus, when deposing Dr. Brooks, appellee did not ask questions typically asked of expert witnesses. Appellants’ actions clearly did not comport with Loc.R. 21.1 or Civ.R. 26(E).
{¶ 23} In Jones v. Murphy (1984), 12 Ohio St.3d 84, 85, 12 OBR 73, 465 N.E.2d 444, this court considered a similar issue when it was asked to decide “whether the Ohio Rules of Civil Procedure permit the exclusion of expert testimony pursuant to a motion in limine as a sanction for the violation of Civ.R. 26(E)(1)(b).”
{¶ 24} Specifically, in Jones, the plaintiffs filed suit against the defendant for damages arising from an automobile accident allegedly caused by the defendant’s negligence. In interrogatories, the defendant requested the name of any experts who would be testifying in the plaintiffs’ behalf; they responded, “Undetermined at present.” Id. at 84, 12 OBR 73, 465 N.E.2d 444. The plaintiffs did not comply with the scheduling order for discovery, nor did they respond to the defendant’s other requests for the identification of the expert witness. Finally, 12 days before trial, the defendant learned by telephone that the plaintiffs intended to call one of their treating physicians as an expert witness. The defendant filed a motion in limine to exclude the physician’s expert testimony, which the court granted, thereby permitting the physician to testify as a fact witness only.
{¶ 25} The appellate court affirmed the judgment of the lower court, and this court affirmed that judgment, reasoning, “One of the purposes of the Rules of Civil Procedure is to eliminate surprise. This is accomplished by way of a discovery procedure which mandates a free flow of accessible information between the parties upon request, and which imposes sanctions for failure to timely respond to reasonable inquiries. [Plaintiffs-appellants] argue that a continuance should have been requested and granted once the expert witness’ identity was discovered by [defendant-appellee]. An intentional violation of the rules should not be so easily disregarded, however.” Id. at 86, 12 OBR 73, 465 N.E.2d 444.
{¶ 26} Applying the reasoning of Jones to the case at bar, appellee made a seasonable request in her interrogatories for appellants to identify anyone who would be testifying as an expert witness. Appellants failed to name Dr. Brooks in their response. Moreover, appellants not only missed the original deadline to *489identify all experts and file expert reports, but they also did not comply with the extended deadline granted by the trial court.
{¶ 27} Appellants’ actions demonstrated a disregard for the orders of the trial court and for the rules and structure of our adversarial process. Dr. Brooks’s belief that he should testify as an expert witness was premised only on his participation as a party to the action as appellee’s original treating physician. To allow such would permit a party who acts as his or her own expert to utilize a different set of rules than those which are in place, leading to an unfair advantage for one party at the expense of the opponent. In this case, the trial court had a responsibility to ensure that there was no unfair prejudice or surprise to appellee; granting the motion in limine ensured such a result.
{¶ 28} Therefore, we hold that the trial court did not abuse its discretion in not allowing Dr. Brooks to testify as an expert witness in his own behalf, after he failed to file a written report and failed to supplement answers to interrogatories asking that expert witnesses be identified. Consequently, we affirm the judgment of the court of appeals.
Judgment affirmed.
