The Clinical Efficacy of Full-length Shoe Inserted Lateral Wedged Insole Combined with Ankle Sprain Supporter for Osteoarthritis of the Knee

Abstract

Objective: The aim of this study was to assess the efficacy of a full-length lateral wedged insole in combination with an ankle sprain supporter for treatment of osteoarthritis of the knee.
Methods: Thirty seven outpatients were prospectively randomized and treated with a lateral wedged insole alone (the insole alone group, n = 19) or an ankle sprain supporter in combination with an insole (the insole with support group, n = 18) for four weeks.
Results: The Lequesne index remission score was significantly improved in the insole with support group (4.1±4.2 points) compared with the insole alone group (1.3±3.2 points) (P = 0.026). The mean value of correction of the femorotibial angle was higher in the insole with support group (1.1±0.84°) than in the insole alone group (0.74±99°), although the difference between the two groups was not statistically significant.
Conclusion: The full-length lateral wedged insole in combination with an ankle sprain supporter will benefit patients with knee osteoarthritis.
