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.

Background Adhesive capsulitis (AC) of the shoulder is a common disorder that painfully reduces the shoulder range of motion (ROM) among middle-aged individuals. Although physical therapy with home-based exercises is widely advised to restore ROM in the treatment of AC, clinical results vary owing to inconsistent patient compliance. Objective In this study, we aimed to verify the feasibility of a treatment model that involves applying a wearable motion sensor device to assist patients conduct home-based exercises to improve training compliance and the accuracy of exercises, with the ultimate goal of improving the functional recovery of patients with AC. Methods The motion sensor device was comprised of inertial measurement unit–based sensors and mobile apps for patients and physicians, offering shoulder mobility tracing, home-based exercise support, and progress monitoring. The interrater reliability of shoulder mobility measurement using the motion sensor device on 10 healthy participants and 15 patients with AC was obtained using an intraclass correlation coefficient analysis and compared with the assessments performed by two highly experienced physicians. A pilot prospective control trial was then carried out to allocate the 15 patients with AC to two groups: home-based exercise group and motion sensor–assisted rehabilitation group. Changes in active and passive shoulder ROM, pain and functional scores, and exercise completion rates were compared between the groups during a treatment period of 3 months. Results Shoulder ROM, as measured using the motion sensor device, exhibited good to excellent reliability based on the comparison with the measurements of two physicians (intraclass correlation coefficient range, 0.771 to 0.979). Compared with patients with AC in the home-based exercise group, those in the motion sensor–assisted rehabilitation group exhibited better shoulder mobility and functional recovery and a higher exercise completion rate during and after 3 months of rehabilitation. Conclusions Motion sensor device–assisted home-based rehabilitation for the treatment of AC is a useful treatment model for telerehabilitation that enhances the compliance of patients through training, thus improving functional recovery. This helps overcome important obstacles in physiotherapy at home by providing comprehensible and easily accessible exercise instructions, enhancing compliance, ensuring the correctness of exercise, and monitoring the progress of patients.

BACKGROUND Adhesive capsulitis (AC) of the shoulder is a common shoulder disorder that painfully reduces the shoulder range of motion (ROM) among the middle-aged population. Although physical therapy with home-based exercises is widely advised to restore range of motion in the treatment of AC, clinical results vary owing to inconsistent compliance. OBJECTIVE This study aims to verify the feasibility of a treatment model that applies wearable motion sensor device (MSD) to assist home-based exercises to improve training compliance and the accuracy of exercises, with the ultimate goal of improving the functional recovery of AC patients. METHODS The MSD comprised inertial measurement unit-based sensors and mobile apps for patients and physicians, offering shoulder mobility tracing, home-based exercise support and progress monitoring. The inter-rater reliability of shoulder mobility measurement using the MSD on ten healthy participants and 15 AC patients was obtained using intraclass correlation coefficient (ICC) analysis and compared to assessments by two highly experienced physicians. A pilot prospective control trial was then carried out to allocate 15 AC patients to two groups – a home-based exercise (HE) group and a motion sensor-assisted rehabilitation (MAR) group. Changes in active and passive shoulder ROM, pain and functional scores and exercise completion rates were compared between groups for a treatment of three months. RESULTS Shoulder ROM, as measured using the MSD herein, exhibited good to excellent reliability by comparison the measurements made by two physicians (ICC range from 0.771 to 0.979). The AC patients in the MAR group exhibited better shoulder mobility and functional recovery and a higher exercise completion rate than the patients in the HE group during and after three months of rehabilitation CONCLUSIONS This investigation shows that MSD-assisted home-based rehabilitation in the treatment of AC is a useful treatment model for tele-rehabilitation that enhances the compliance of patients with training, improving functional recovery, the overcoming of important obstacles in physiotherapy at home by providing comprehensible and easily accessible exercise instructions, compliance, exercise correctness, and the monitoring of progress.

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.

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.

Abstract Background To explore whether previous arthroscopic knee surgery affects future total knee arthroplasty (TKA) results or not. Methods A total of 56 patients with the previous arthroscopic treatment on one knee underwent subsequent bilateral total knee arthroplasty in our hospital from September 2012 to July 2018. Data on each patient were collected in regards to changes in postoperative clinical and functional scores, various other scores, as well as postoperative functional recovery and complications. We defined the knees with a previous arthroscopic history as group A, and the counter side as group B. The Knee Society clinical score, functional scores, range of motion (ROM), finger joint size (FJS), visual analogue scale (VAS) scores were assessed before and after surgery. Using the Kolmogorov-Smirnov Test to test the normality of continuous variables, and the chi-square test to compare the rate of reoperation and complications between two groups. For all statistical comparisons, P < 0.05 was considered significant. Results There were no statistically significance differences found in postoperative Knee Society clinical scores and functional scores between group A and group B, as well as in ROM, FJS, VAS scores and local complications. Conclusion There were no statistically significant differences found in postoperative functional recovery and complications in patients, who underwent total knee arthroplasty with previous knee arthroscopy.
