| Objective: To explore the effect of knee varus orthosis on patients with knee osteoarthritis. Methods: A total of 60 knee osteoarthritis patients with knee varus were selected and randomly divided into an orthosis group and a control group. Both groups received conventional treatment, with the orthosis group receiving knee varus orthosis and the control group receiving traction treatment. After 4 weeks of treatment, knee joint function was evaluated using Visual Analog Scale (VAS), Joint Range of Motion (ROM), Western Ontario and McMaster University Osteoarthritis Index (WOMAC), United States Hospital of Special Surgery Knee Score (HSS), Tibiofemoral Angle (TFA), and Knee Distance (IC). Results: After 4 weeks of treatment, the VAS, WOMAC, and IC scores of both groups decreased compared to those before treatment (P<0.01), and those in the observation group were lower than in the control group (P<0.01). After treatment, the HSS and TFA scores of both groups were improved compared to those before treatment, and those in the observation group were higher than those in the control group (P<0.01,0.05). There was no statistically significant difference in ROM scores within and between the 2 groups. Conclusion: Knee varus orthosis can alleviate pain, improve knee function, improve lower limbs biomechanics, and slow down the progression of knee varus in KOA patients. It is worthy of clinical promotion and application. |
