Analyze subjects with symptomatic unicompartmental OA under in vivo, dynamic weight-bearing conditions to determine if different off-loading knee braces provide medial femoral condyle separation from the tibial plateau, thus avoiding excessive loads on the degenerated compartment.

DonJoy OA Adjuster provides a high amount of medial condylar separation.

Investigate the efficacy of knee valgus braces and lateral wedging in subjects with medial compartment OA of the knee, through advanced biomechanical testing of walking and single limb stance.

Significant improvements were seen in the angulation of the knee in the coronal plane during stance phase with both the valgus brace and the 5 degree lateral wedge.

Exercise and physical activity programs have been shown to reduce pain and improve function in patients with knee osteoarthritis
(OA). The key to a flexibility and mobility program is to address limitations in all lower extremity joints. There is growing interest in the use of balance and agility training activities in knee OA exercise programs.

Greater load in the medial compartment of the knee than in the lateral compartment may contribute to knee osteoarthritis (OA). Malalignment also has been associated with the progression of radiographic joint-space loss and loss of function. Knee bracing may correct malalignment, reduce the load, reduce the varus moment, increase proprioception, and stabilize an unstable knee.
