Abstract Background This randomized controlled study compared standard supervised physiotherapy (SPT) with a self-developed, home-based, enhanced knee flexion exercise program involving a low stool (KFEH) in patients who underwent total knee arthroplasty (TKA). Methods Patients were recruited from July 2014 to December 2015 and randomly assigned to one of two groups: KFEH (n = 60) and SPT (n = 59). Outcomes (joint function) were evaluated according to the Knee Society Score (KSS), visual analog scale (VAS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, and range of motion (ROM) assessment at selected time points (preoperatively; 1 week; 1, 3, and 6 months; and 1 year after surgery). Results Pain and functional improvement were observed in both groups. Non-inferiority of KFEH was evident 12 months postoperatively; however, patients in the KFEH group exhibited better ROM at 1 month (P < 0.01). Absolute WOMAC and KSS scores were slightly better in the KFEH group, although the difference was not statistically significant. There was no difference in VAS scores and complication rates between the two groups. Additionally, the home program would save patient time and decrease the economic burden associated with in-hospital SPT. Conclusion Considering rehabilitation and economic efficiency as well as the COVID pandemic, a home-based enhanced knee flexion exercise program for TKA rehabilitation is recommended.

Purpose: The purpose of this study was to assess the effectiveness of periarticular multidrug infiltration (PMDI) and compare it with that of epidural catheter use. Methods: Fifty-eight patients (58 joints) who underwent total knee arthroplasty were included in this single-center, prospective, parallel, randomized, controlled trial. Preoperatively, patients were randomly categorized into the PMDI and epidural catheter groups. We evaluated postoperative pain (visual analog scale (VAS) and narcotic consumption), functional outcomes (range of motion (ROM) of knee flexion, the day patients could perform the straight-leg raising (SLR) test, and day of starting cane use), and laboratory data (white blood cell (WBC) and C-reactive protein (CRP)). Results: There was no significant difference in the VAS score, ROM of knee flexion, the day patients could do SLR, and the day of starting cane use between the PMDI and epidural catheter groups. However, the PMDI group could perform SLR on a postoperative day (POD) 1 ( p < 0.05). WBC level on POD 1 was significantly higher in the PMDI group ( p < 0.05), whereas the CRP levels on POD 1 ( p < 0.01), 3 ( p < 0.01), and 5 ( p < 0.01) were significantly lower in the PMDI group than in the epidural catheter group. The frequency of side effects was not significantly different between the groups. Conclusion: PMDI was as effective as epidural catheter use for pain control. A higher percentage of patients who underwent PMDI could perform SLR on POD 1; therefore, the functional recovery was earlier in the PMDI group than in the epidural catheter group. PMDI may suppress inflammation in the whole body because of steroids.

BACKGROUND Total knee arthroplasty (TKA) is an effective procedure for patients with end-stage knee osteoarthritis. Postoperative rehabilitation programs are essential for facilitating functional recovery after TKA. However, clinical results vary because of inconsistent patient compliance. OBJECTIVE This study aimed to verify the feasibility of a treatment model that involves applying a wearable motion sensor device (MSD) to assist patients in performing home-based exercises after TKA. METHODS The MSD comprised inertial measurement unit–based sensors and mobile apps for patients and physicians, which allowed for knee mobility tracing, home-based exercise support, and progress monitoring. The interrater reliability of knee mobility measurements was assessed using the intraclass correlation coefficient (ICC). Different knee flexion angles and the time spent for completing the 5-times sit-to-stand test (5TSST) in 12 healthy participants were measured by 2 experienced physicians and using the MSD, and their results were compared using ICC. A pilot prospective control trial was then conducted, in which 12 patients following TKA were allocated to 2 groups: the home-based exercise group and the MSD-assisted rehabilitation group. Changes in knee range of motion, pain, functional score (assessed using the Western Ontario and McMaster Universities Arthritis Index), performance (tested using 5TSST), and exercise completion rates were compared between the groups over 2 months of follow-up. RESULTS Knee flexion at different angles and the time spent for completing 5TSST measured using the MSD exhibited excellent reliability compared with the physician measurements (ICC range: 0.996 and 0.996 respectively). Furthermore, patients in the MSD-assisted rehabilitation group reported higher exercise completion rate within 2 months of the in-home exercise program compared with participants in the home-based exercise group, which lead to more favorable outcomes in the knee extension angle and maximal and average angular velocity in 5TSST. CONCLUSIONS MSD-assisted home-based rehabilitation following TKA is a useful treatment model for telerehabilitation because it enhances patients’ compliance to training, which improves functional recovery. This method helps overcome critical obstacles in home-based physiotherapy among patients after TKA. Therefore, this study has crucial implications for patients and health systems.

AbstractThis study aimed to evaluate whether manipulation under anesthesia (MUA) affect clinical outcome including range of motion (ROM) and patient satisfaction after total knee arthroplasty (TKA). It is hypothesized that MUA improves clinical outcomes and patient satisfaction after primary TKA. This retrospective study analyzed 97 patients who underwent staged bilateral primary TKA. MUA of knee flexion more than 120 degrees was performed a week after index surgery just before operation of the opposite site. The first knees with MUA were classified as the MUA group and the second knees without MUA as the control group. ROM, Knee Society Knee Score, Knee Society Functional Score, Western Ontario and McMaster Universities (WOMAC) score, and patient satisfaction were assessed. Postoperative flexion was significantly greater in the MUA group during 6 months follow-up (6 weeks: 111.6 vs. 99.8 degrees, p < 0.001; 3 months: 115.9 vs. 110.2 degrees, p = 0.001; 6 months: 120.2 vs. 117.0 degrees, p = 0.019). Clinical outcomes also showed similar results with knee flexion during 2 years follow-up. Patient satisfaction was significantly high in the MUA group during 12 months (3 months: 80.2 vs. 71.5, p < 0.001; 6 months: 85.8 vs. 79.8, p < 0.001; 12 months: 86.1 vs. 83.9, p < 0.001; 24 months: 86.6 vs. 85.5, p = 0.013). MUA yielded improvement of clinical outcomes including ROM, and patient satisfaction, especially in the early period after TKA. MUA in the first knee could be taken into account to obtain early recovery and to improve patient satisfaction in staged bilateral TKA.

AbstractDespite multiple studies, there remains a debate on the safety of bilateral total knee arthroplasty (BTKA) in the average age patient, with a paucity of data on the outcome of BTKA in an elderly population. This study included 89 patients aged 80 years and older undergoing sequential BTKA over 14 years were identified in a prospectively collected database. Two matched comparison groups were created: patients under 80 undergoing sequential BTKA and patients over 80 undergoing unilateral TKA (UTKA). An analysis of complications, mortality, revision, and patient-reported outcome measures was performed. Mean age of the elderly cohorts was similar: 82.6 for BTKA and 82.9 for UTKA. The average age BTKA cohort had a mean age of 69.1. Complication rates were higher in bilateral cohorts, more so in the elderly BTKA cohort. Pulmonary embolism (PE) was observed in bilateral cohorts only. In these patients, history of PE and ischemic heart disease was a strong predictive factor for developing a major complication. There was no difference in revision rates and infection rates between the three cohorts, and no difference in patient survivorship between the two elderly cohorts. Through the combination of low revision and high survivorship rates and comparable clinical outcomes, this article demonstrates that simultaneous BTKA is an appropriate option to consider for an elderly patient, with proper patient selection and perioperative management. The demonstrated risk groups show that emphasis on patient selection should be focused on medical history rather than chronological age.

Abstract Introduction Because of the ongoing discussion of imageless navigation in total knee arthroplasty (TKA), its advantages and disadvantages were evaluated in a large patient cohort. Methods This retrospective analysis included 2464 patients who had undergone TKA at a high-volume university arthroplasty center between 2012 and 2017. Navigated and conventional TKA were compared regarding postoperative mechanical axis, surgery duration, complication rates, one-year postoperative patient-reported outcome measures (PROMs) (WOMAC and EQ-5D indices), and responder rates as defined by the criteria of the Outcome Measures in Rheumatology and Osteoarthritis Research Society International consensus (OMERACT-OARSI). Results Both navigated (1.8 ± 1.6°) and conventional TKA (2.1 ± 1.6°, p = 0.002) enabled the exact reconstruction of mechanical axis. Surgery duration was six minutes longer for navigated TKA than for conventional TKA (p < 0.001). Complication rates were low in both groups with comparable frequencies: neurological deficits (p = 0.39), joint infection (p = 0.42 and thromboembolic events (p = 0.03). Periprosthetic fractures occurred more frequently during conventional TKA (p = 0.001). One-year PROMs showed excellent improvement in both groups. The WOMAC index was statistically higher for navigated TKA than for conventional TKA (74.7 ± 19.0 vs. 71.7 ± 20.7, p = 0.014), but the increase was not clinically relevant. Both groups had a similarly high EQ-5D index (0.23 ± 0.24 vs. 0.26 ± 0.25, p = 0.11) and responder rate (86.5% [256/296] vs. 85.9% [981/1142], p = 0.92). Conclusion Both methods enable accurate postoperative leg alignment with low complication rates and equally successful PROMs and responder rates one year postoperatively. Level of evidence III. Retrospective cohort study.
