Manipulation under Anesthesia for Stiffness of the Knee Joint after Total Knee Replacement.

ABSTRACT: BackgroundStiffness of the knee joint is a feared complication after total knee replacement (TKR). An initial noninvasive treatment option is the manipulation of the knee under anesthesia (MUA). The purpose of this study is to evaluate the midterm result of the MUA for joint stiffness after primary TKR.MethodsPatients treated with the MUA for knee stiffness after primary TKR surgery performed at Akershus University Hospital during 2014-2018 were invited to a follow-up clinic. The range of motion (ROM) of the knee joint was measured using a goniometer, and the patients reported the Lysholm score, Knee injury and Osteoarthritis Outcome Score, and Tegner score. In addition, any complications or reoperation after the MUA was noted.ResultsA total of 24 patients were identified in the journal system at the hospital. Twenty-three of these (17 women and 6 men) attended the designated follow-up on average 26 months (range [r], 16-35) after the MUA. The total ROM was 97° (r, 84°-116°) at the time of follow-up, compared with 70° (r, 50°-80°) before the MUA (P < .001, the Mann-Whitney U-test). A regression analysis indicated that the ROM at follow-up was predicted by the time from the index TKR surgery to the MUA, with the early MUA improving results (P = .02). The median Lysholm score was 57.1 (r, 17.9-92.9).ConclusionsThere is a clinically and statistically significant increase of the total ROM of the knee joint after the MUA for knee stiffness after TKR. The earlier MUA yields a better total ROM. Despite improvement in the ROM, the patients did not achieve normal function of the knee joint.

Project description:BackgroundArthrofibrosis after total knee arthroplasty (TKA) is a common complication, potentially occurring in up to 25% of patients, and may be treated during the early recovery period by manipulation under anesthesia (MUA). The majority of preoperative factors that predispose patients to postoperative stiffness are patient specific and not modifiable. The United States Veteran Affairs is a particularly challenging group given a higher baseline rate of medical comorbidities and opioid dependence than the general population. Patient education about postoperative expectations and complications has been shown to improve outcomes in certain orthopedic procedures. This retrospective study aims to determine if preoperative counseling for veterans undergoing primary TKA reduces the rate of postoperative stiffness, and consequently MUA, in this subset of patients.MethodsWe evaluated the medical records of 244 veterans at a single veteran affairs hospital who underwent 278 TKAs during a 6-year period under one surgeon. Patients were separated into groups based on attendance in the preoperative counseling session. Effects of various factors, including age, sex, body mass index, preoperative knee range of motion, and history of previous knee surgery, were compared between these 2 cohorts.ResultsAttendance in the preoperative course did not have a statistically significant impact on the rate of manipulation (odds ratio [OR], 1.07). Female gender and prior manipulation had an increased OR of knee manipulation, whereas age > 65 years had a decreased OR that did not reach significance.ConclusionsOur results show that preoperative counseling did not have a benefit in terms of postoperative MUA rates in veterans. Preoperative education may be helpful for setting appropriate expectations of pain, recovery, and function after total joint arthroplasty and may be useful in an online or video format in small practices in which cost may be prohibitive. Further studies are needed to determine whether they provide any benefit in postoperative arthrofibrosis rates.
