Project description: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:Background and purpose - The incidence of manipulation under anesthesia (MUA) after knee arthroplasty surgery has been reported to vary between 0.5% and 10%. We evaluated the incidence of MUA after primary knee arthroplasty in Sweden, the demographics of the patients and the risk of revision. Patients and methods - Between 2009 and 2013, 64,840 primary total and unicompartmental knee arthroplasties (TKA and UKA) were registered in the Swedish Knee Arthroplasty Register (SKAR). MUAs performed between 2009 and 2014 were identified through the in- and outpatient registers of the Swedish National Board of Health and Welfare. Pertinent data were verified through medical records and patient demographics and revisions were obtained from the SKAR. Results - 1,258 MUAs were identified. Of these, 1,078 were 1st-time MUAs, performed within 1 year after the primary knee arthroplasty. The incidence of MUA was 1.7% and the incidence varied between hospitals from 0% to 5%. The majority were performed after TKA (98%), in younger patients (65% < 65 years), women (64%), and relatively healthy persons (88% had ASA ? 2). The cumulative risk of revision at 10 years was 10% (95% CI 8.6-12), similar for men and women. Interpretation - In Sweden, MUA is a rather uncommon measure after knee arthroplasty, especially after UKA. The CRR at 10 years was doubled compared to the general knee arthroplasty population. The frequency of the procedure varies between hospitals but in general it is performed more frequently in healthier and younger patients.

Project description:Background and purposeManipulation under anesthesia (MUA) is the first-choice treatment for stiffness following total knee arthroplasty (TKA) unresponsive to pain management and physiotherapy. Some of the predisposing factors and patient-reported outcome measures (PROMs) following MUA remain poorly studied. We retrospectively investigated the etiological risk factors and the outcomes of MUA.Patients and methods391 TKA patients from a randomized trial comparing the use of a tourniquet and anesthesia (spinal or general) were analyzed, and patients needing MUA were identified (MUA group). We evaluated in-hospital opioid consumption, Oxford Knee Score (OKS), range of motion (ROM), and pain assessed by the Brief Pain Inventory-short form with a 1-year follow-up.Results39 (10%) MUA patients were identified. The MUA patients were younger (60 years vs. 64 years, difference -4, 95% CI -6 to -1) and had higher postoperative oxycodone consumption (66 mg vs. 51 mg, median difference 11, CI 1-22) than the no-MUA patients. The proportion of MUA patients who contacted the emergency department within 3 months because of pain was larger than that of non-MUA patients (41% vs. 12%, OR 5, CI 3-10). At the 1-year follow-up, the ROM was improved by 39° following MUA, but the total ROM was worse in the MUA group (115° vs. 124°, p < 0.001). No difference was found in the OKS between the MUA and no-MUA patients.InterpretationHigher postoperative pain seems to predict MUA risk. MUA performed 3 months postoperatively offers substantial ROM improvement and comparable PROMs to no-MUA patients 1 year after TKA.

Project description:PurposePrognostic factors associated with Manipulation under anesthesia (MUA) failure remain unknown.MethodsA systematic review of the literature was performed to identify studies that reported prognostic factors associated with MUA for postoperative stiffness.Results7 studies analyzing prognostic factors associated with MUA outcomes were included. Several studies note pre-MUA ROM to be a significant prognostic factor affecting post-MUA ROM at final follow-up. Knees with <70° of flexion pre-MUA had less final flexion arc than those with >70°.ConclusionsThe strongest prognostic factor for decreased ROM after MUA is severe pre-MUA stiffness.

Project description:BackgroundThe ideal treatment of early-stage arthrofibrosis after total knee arthroplasty is unclear. The purpose of this study was to determine the treatment effect, including variability, and feasibility of a multimodal physical therapy program as compared to manipulation under anesthesia.MethodsThis was a prospective feasibility study with a retrospective cohort comparison. Ten consecutive patients (aged 64 ± 9 years, 7 females) with early-stage arthrofibrosis were enrolled 6 weeks after primary total knee arthroplasty and participated in the multimodal physical therapy program. The multimodal physical therapy program consisted of manual therapy, therapeutic exercise, and static progressive splinting delivered over 4 weeks. The outcomes included knee range of motion (ROM), adherence, patient satisfaction, and safety. Data were compared to a retrospective cohort of 31 patients with arthrofibrosis (aged 65 ± 9 years, 20 females) who underwent manipulation under anesthesia followed by physical therapy.ResultsOverall, knee ROM outcomes were similar between multimodal physical therapy (110° ± 14) and manipulation under anesthesia (109° ± 11). Seven out of ten patients achieved functional ROM (≥ 110°) and avoided manipulation under anesthesia with the multimodal physical therapy program. Three out of 10 multimodal physical therapy patients required manipulation under anesthesia secondary to failure to demonstrate progress within 4 weeks of the multimodal physical therapy program. Adherence to the multimodal physical therapy program was 87 ± 9%. The median patient satisfaction with the multimodal physical therapy program was "very satisfied." Safety concerns were minimal.ConclusionThe use of the multimodal physical therapy program is feasible for treating early-stage arthrofibrosis after total knee arthroplasty, with 70% of patients avoiding manipulation under anesthesia. Randomized controlled trials are needed to determine the efficacy of the multimodal physical therapy program and to determine the optimal patient selection for the multimodal physical therapy program versus manipulation under anesthesia.Trial registrationClinicalTrials.gov, NCT04837872 .

Project description:Arthrofibrosis is a known complication after knee surgery, resulting in stiffness and decreased range of motion for patients. Manipulation under anesthesia is a commonly used technique to address postoperative arthrofibrosis after knee surgery. Often, direct pressure is applied to the knee during the manipulation. This can be difficult and can place undue stress above and below the joint. This Technical Note presents the technique for manipulation under anesthesia using gravity and the native knee motion alone to improve knee range of motion.

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.

Project description:Manipulation under anesthesia (MUA) has been used to speed up the recovery of frozen shoulder, which is said to be a self-limiting process. We would like to elucidate the short- and long-term results of the treatment of frozen shoulders by manipulation under anesthesia and compare the results of idiopathic, post-trauma and post-surgery frozen shoulders. We applied an adjusted Constant score (Constant score after excluding the 25 points allocated for the assessment of muscle strength) to assess all patients. In our series, 47 cases with 51 frozen shoulders were collected and evaluated retrospectively. The adjusted Constant score at pre-manipulation was on average 22.8+/-4.9 (10-31) points. The score from the 3-week follow-up was 52.6+/-9.2 (31-67) points on average. The score from the averaged 82-month follow-up was on average 70.1+/-6.2 (54-75) points, with 23 shoulders scored for a maximum point number of 75. The score at the early and late follow-ups was significantly lower for the post-surgery group (63.2+/-6.7) when compared to the other two groups (P<0.001). Our results revealed that manipulation under anaesthesia is a very simple and noninvasive procedure for shortening the course of an apparently self-limiting disease and can improve shoulder function and symptoms within a short period of time. However, we found less improvement in post-surgery frozen shoulders, especially in residual pain and limited range of motion (ROM), which may be influenced by the initial injury or initial surgery. Although less improvement in pain and ROM was noted, manipulation is still a good and simple way to treat post-surgery frozen shoulders.

Project description:Post-traumatic knee stiffness can present after injuries around the knee and surgery. Management is guided by the type of initial injury, amount of range-of-motion loss, time since injury, and cartilage status. Cases refractory to conservative management may conventionally be treated with manipulation under anesthesia (MUA), arthroscopic lysis of adhesions, or open quadricepsplasty. We describe our arthroscopic technique of lysis of adhesions with anterior interval release and intraoperative MUA, which has been shown to provide sustainable range-of-motion improvement in a subset of patients with severe knee arthrofibrosis. Although technically demanding, this technique benefits from being minimally invasive, allows for direct visualization of intra-articular structures, and allows all-round arthroscopic release of adhesions to improve patellar mobility and decrease the risk of fracture prior to MUA. A rigorous postoperative formal physical therapy protocol and patient compliance are imperative to achieve good outcomes.

Project description:PurposeTo investigate the efficacy of manipulation under anesthesia (MUA) compared to other non-surgical therapeutic strategies for patients with frozen shoulder contracture syndrome (FSCS).MethodsA systematic review of literature was conducted. A literature search was performed in MEDLINE, EMBASE, PEDro, Cochrane Central Library and Scopus. Only randomized controlled trials were included and assessed for critical appraisal through the Cochrane Collaborations tools.ResultsFive randomized controlled trials were included. The overall risk of bias (RoB) was high in 4 out of 5 of the included studies. MUA was found to be not superior in terms of reduction of pain and improvement of function when compared to cortisone injections with hydrodilatation (mean regression coefficient MUA -2.77 vs. injection -2.75; 95% CI (-1.11 to 1.15)) and home exercise (mean difference 95% CI: 0.2 (-0.64 to 1.02)) in the short term (3 months), and cortisone injections with hydrodilatation (mean regression coefficient MUA 3.13 vs. injection 3.23; 95% CI (-0.90 to 1.11)) in the long term (>6 months). Moreover, if compared to structured physiotherapy, MUA highlighted a higher Oxford Shoulder Score at final 1-year follow up (mean difference 95% CI: 1.05 (-1.28 to 3.39); p = 0.38). Similar results were obtained for disability, with statistically no significant long-term (>12 months) differences between MUA and home exercise (mean difference 95% CI: 0 (-3.2 to 3.2)) or structured physiotherapy (mean difference 95% CI: -0.50 (-5.70 to 4.70); p = 0.85)). Only two trials reported adverse events.ConclusionsThis review suggested that limited and inconsistent evidence currently exists on the efficacy of MUA compared to other non-surgical strategies in the management of patients with FSCS. Future research should focus on clinical trials with higher methodological quality.
