Evaluation of off-loading braces for treatment of unicompartmental knee arthrosis.

Two analyses were performed to assess the effectiveness of off-loading knee braces in producing condylar separation of degenerative compartments in patients with unicompartmental knee osteoarthritis. All patients were analyzed using video fluoroscopy under weight-bearing conditions. In the initial study, a single brace was analyzed in 2 dimensions and demonstrated that medial condylar separation was obtained, with corresponding pain relief, in 78% of patients. The brace was least effective in obese patients. The second study consisted of a 3-dimensional analysis of 5 subjects fitted with 5 different off-loading braces. Condylar separation in most patients was similarly observed with certain braces, whereas others demonstrated little to no condylar separation, suggesting that off-loading knee braces are not equally effective in treatment of unicompartmental knee arthritis.
