In situations involving lateral unicompartmental arthritis unresponsive to conservative treatment options, the Distal Femoral Opening Wedge Osteotomy System is a safe, reproducible alternative to traditional closing wedge distal femoral osteotomies. The system is designed to correct valgus malalignment through the knee joint and is carried out through a distal lateral femoral approach.
In a simplified technique, an opening wedge osteotomy is performed originating from the distal femoral diaphyseal-metaphyseal flare avoiding surgical exposure to the medial side of the distal femoral region. The osteotomy is supported by one in a series of Femoral Osteotomy Plates and secured with traditional proximal bicortical screw and distal cancellous screw fixation.
To help promote healing, provide added rigidity to the repair biologics such as OSferion Osteotomy Wedge (AR-13370-01-04), Arthrex Quickset™, StimuBlast®*, Demineralized Bone Matrix, and Autologous Conditioned Plasma may be used.
