Medial Closed Wedge Distal Femoral Osteotomy Using a Novel Plate With an Optimal Compression System.

ABSTRACT: Medial closed wedge distal femoral osteotomy (MCWDFO) has been widely performed for lateral-compartment osteoarthritis since the development of a biplanar osteotomy technique using existing MCWDFO-specific plates. To further improve this system and the technique, we have developed a newly designed MCWDFO plate (TriS-MDFO; Olympus Terumo Biomaterials). The improved shape of the plate consists of a larger head-shaft angle to fit the distal femur after MCWDFO, more distally oriented distal screws to enable longer screw insertion, and a diamond-shaped plate head to avoid interference with the medial patellofemoral ligament. Technically, to overcome the difficulty in inserting proximal screws through the vastus medialis muscle, a cannulated screw system was employed. This system can prevent dif
