Distal Medial Closed Wedge Varus Femur Osteotomy Stabilized With the TomoFix Plate Fixator

Total or near total resections of the lateral meniscus are often followed by a lateral osteoarthritis of the knee. In the past, various possibilities concerning the surgical treatment of lateral osteoarthritis or valgus malalignment were described. The goal of all these different procedures was to unload the lateral compartment of the knee while shifting the mechanical leg axis from the lateral to the medial compartment. Unfortunately, many of these methods often were followed by local complaints or complications in wound or bone healing. Often additional surgeries were necessary as the result of insufficient fixation stability. This is why a new improved surgical technique based on an incomplete closing wedge osteotomy, fixed with an internal plate fixator was developed. We present the indication of this technique, the preoperative planning, the step-by-step surgical technique, and the first results.
