Abstract

Chiba osteotomy is an effective technique for advanced knee osteoarthritis (KOA). The principle of the osteotomy is to correct both varus deformity and intra-articular joint congruity through an L-shaped osteotomy from the medial tibial condyle to the lateral intercondylar eminence. Previous studies have demonstrated that Chiba osteotomy is an effective method for alignment correction surgery for severe knee osteoarthritis. However, these reports slightly differ from the original concept of Chiba osteotomy. This report describes the pre-operative planning and surgical technique of Chiba osteotomy for patients with large tibial varus deformity, focusing on the management of early knee osteoarthritis following conditions such as post-traumatic Blount disease and “Pagoda” like proximal tibia varus deformities, as originally described.
