Abstract

Background: There are many opinions and controversies regard the effect of lateral wedge insoles and valgus stress 3point knee braces in treatment of medial compartment knee osteoarthritis (OA). In this study we compared the effect of lateral wedge insoles and 3 point knee supports in treatment of medial compartment knee OA.
Method: Sixty patients (35-65 years), with knee pain and genu varum and moderate to severe medial compartment DJD were divided into three groups. The first group received a custom molded 3 point valgus stress knee support. Lateral wedge insoles were applied for the second group and the third group served as control. All groups were followed for 9 months according to pain severity, walking distance, and radiologic changes.
Results: Pain reduced significantly in both lateral wedge and knee brace groups compared to control group with more significant reduction in the brace group. The walking distance was significantly longer only in the brace group. There was more pronounced effect of brace in patients with severe DJD in walking distance compared to moderate DJD, but not in severity of pain.
Conclusion: Three point valgus stress knee support had more significant effect on pain reduction, walking distance and also radiologic improvement of patients with moderate to severe medial compartment DJD compared to lateral wedge insoles and could even reverse radiologic findings.
