Purpose: The purpose of this study is to investigate the effects of interference current therapy and laser therapy on functional recovery after total knee arthroplasty by measuring the Berg balance scale and range of motion. Methods: Subjects were 30 patients who were admitted to G Hospital after total knee arthroplasty. They were randomly assigned to experimental group I in which interference current therapy was applied (n=10), experimental group II in which laser therapy was applied (n=10), or the control group (n=10). The Berg balance scale and range of motion of the subjects were measured before, after 2 weeks, and after 4 weeks of therapy. Results: There was a statistically significant change (p<0.05) in the Berg balance scale and range of motion before and after therapy intervention among the laser therapy group and the interference current therapy group. There was also a significant change between the groups in the Berg balance scale and range of motion. Tukey's post hoc comparison showed a statistically significant difference between the control group and experimental group I and between the control group and experimental group II (p<0.05). Conclusion: The application of interference current therapy and laser therapy resulted in a significant change in both the Berg balance scale and range of motion among patients with total knee arthroplasty. The findings of this study can be used as preliminary clinical data in evaluating functional recovery in patients with total knee arthroplasty in a post-clinic setting.

Objectives To assess the effectiveness of chuna manual therapy for patients with total knee arthroplasty. Methods We searched 9 electronic databases(KISS, NDSL, RISS, OASIS, KMBASE, Cochrane Library, PubMed, CNKI, Wangfang data) using the keywords 'total knee arthroplasty OR total knee replacement' and 'tuina OR chuna' to identify RCTs that investigated the effectiveness of Chuna manual therapy after total knee arthroplasty. Results 23 RCTs were selected based on inclusion criteria. The systematic review showed positive effect of using chuna manual therapy after total knee arthroplasty. Conclusions 23 studies reported that chuna manual therapy had significant effects on total knee arthroplasty. However, many studies were exposed to probable high risk of bias. Also, all of the studies were published in one overseas country. Therefore, further research is required using well-designed RCTs to support the effectiveness of chuna manual therapy.

A knee joint's longevity depends on the proper integration of structural components in an axial alignment. If just one of the components is abnormally off-axis, the biomechanical system fails, resulting in arthritis. The complexity of various failures in the knee joint has led orthopedic surgeons to select total knee replacement as a primary treatment. In many cases, this means sacrificing much of an other-wise normal joint. Here, we review novel computational approaches to describe knee physiotherapy by introducing a new dimension of foot loading to the knee axis alignment producing an improved functional status of the patient. New physiotherapeutic applications are then possible by aligning foot loading with the functional axis of the knee joint during the treatment of patients with osteoarthritis.

Gentamicin-loaded bone cement used in total joint arthroplasty is indispensable, as it provides stability by directly binding the surfaces of implants and bones. Depending on multiple factors, including the material of the bone cement used, common complications, such as aseptic loosening, osteolysis, and infection can occur postoperatively. In clinical practice, Doujet bone cement is easy to handle (pre-packed all-in-one system), and has shown low failure rates and non-inferior results compared with similar available products. We conducted a retrospective comparative study to analyze the clinical and radiological results of each bone cement group to establish the safety and usefulness of Doujet bone cement. From July 2020 to July 2022, we enrolled 198 patients in this study after an average follow-up period of 37 months (range, 6-48 months). In 99 patents, Doujet^® bone cement (Injecta, Gunpo, Korea) was used for total knee arthroplasty (TKA), while Refobacin^® bone cement (Biomet, Warsaw, IN, USA) was used in 99 patients. The average range of motion (ROM) of the knee increased by 2.4° (from 127.0° preoperatively to 129.4° postoperatively) in the Doujet group, and by 0.1° (from 128.7° to 128.8°) in the Refobacin group (P=0.701). The Western Ontario and McMaster Universities (WOMAC) osteoarthritis index scores decreased from 44.1 to 7.8 in the Doujet group, and from 44.2 to 6.3 in the Refobacin group (P=0.162). Complications, such as osteolysis or post-operative wound infection, did not occur in more than two cases in both groups. The WOMAC and ROM of the knee in both groups had no clinical differences. Both Doujet and Refobacin similarly showed low complication rates after TKA.

Purpose: The purpose of this study was to examine the factors affecting changes in Korean Knee Score (KKS) and ranges of motion (ROM) of the knee after the structured exercise programs for the patients with total knee arthroplasty. Methods: This was a retrospective study using electronic medical records from January 2015 to February 2017, and the subject of this study was a total of 124 out of 434 patients underwent total knee replacement operation. They took part in a structured step-by-step exercise program conducted by orthopedic nurses, and then were evaluated for KKS and Knee ROM for 12 weeks after operation. Results: Post-intervention scores increased significantly in the KKS subdomains including pain and symptoms (t=-22.31, p<.001), function (t=-20.68, p<.001), evaluation of floor life (t=-14.18, p<.001), socioemotional function (t=-28.94, p<.001) over time. As for the change in the ROM, knee extension (t=9.23, p<.001) and knee flexion (t=4.04, p<.001) showed a statistically significant changes over time. Conclusion: This study illuminated the factors affecting the changes in pain and symptom, physical function, evaluation of floor life, socioemotional function and range of motion after structured exercise training programs for knee arthritis patients.

Objective: The objective of this study was to investigate the differences in the quality of life between two groups of patients who received or did not receive total knee replacement (TKR) surgery after being diagnosed with knee osteoarthritis (OA), and to investigate changes in the quality of life for persons who had TKR surgery. Design: Cross-sectional study. Methods: The subjects were randomized into a surgery group (n=70) and a non-surgery group (n=65). Subjects were selected from individuals diagnosed with knee OA from Himchan Hospital in Seoul, South Korea. Their sex, age, weight, height, body mass index, unilateral or bilateral, and quality of life were evaluated. Changes in the quality of life was measured using the Short Form-36 Health Survey (SF-36). Seventy out of 135 patients had TKR surgery, and their quality of life was evaluated at 6 months and 12 months after the surgery. Results: SF-36 scores were significantly improved at 6 months and 12 months after the surgery compared to the scores before the surgery (p<0.05). Also, the comparison between 6 and 12 months after surgery showed that the Vitality and Social Function scores in the SF-36 were significantly increased (p<0.05). Conclusions: The findings of this study showed that TKR surgery has a positive effect on the quality of life for persons with knee OA as a therapeutic intervention.

Objective: Degenerative knee arthritis is the most common disease that occurs in older people. Constriction-induced movement therapy (CIMT) has been reported to be as an effective treatment for the impairments, such as asymmetric weight-bearing and reduced balance that occurs after receiving a total knee replacement (TKR). Game-based rehabilitation training for persons with TKR is interesting and provides a variety of feedback. Design: Randomized controlled trial. Methods: Thirty-six subjects with TKR were randomly assigned to either the CIMT game training (n=12), general game training (n=12), or the control (n=12) group. Each group underwent twelve sessions (30 min/d, 3 d/wk for 4 weeks). In the CIMT game training group, the application of CIMT adjusted the weight of the pressure delivered from the two boards used in Wii games. In the general game training group, the game was played without adjusting the weight of pressure. The game training used the Wii Fit's Ski Slalom application. Subjects were assessed with the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and the Activities-specific Balance Confidence (ABC) Scale. Results: All three groups showed significant improvements in pain, stiffness and physical function, total WOMAC scores, and ABC scores after the intervention (p<0.05). Significant differences were observed in physical function, total WOMAC scores, and ABC scores of the CIMT game training group compared with the other groups (p<0.05). Conclusions: The CIMT game training and general game training exhibited improvements on stiffness, but the CIMT game training exhibited a larger effect on lower extremity function and balance confidence levels.
