Core Tip
Core Tip: This study focused on Schatzker type 3 (i.e., simple lateral plateau depression fracture) and Schatzker type 5 with lateral plateau depression fractures. Schatzker type 3 fractures are mostly caused by direct impact of the femoral condyle on the lateral plateau. The depressed fracture can occur at any position on the lateral plateau, and the central-posterior position is more common. If the depression is not corrected during surgery, it may cause knee joint bony instability and have a significant impact on joint function. We used the modified Gerdy tubercle osteotomy to treat this type of fracture and achieved good results.
