Ground reaction vector re-adjustment-the secret of success in treatment of medial compartment knee osteoarthritis by novel high fibular osteotomy

High fibular osteotomy has been preliminarily proved to be an effective treatment of knee osteoarthritis by excising a segment of bone at the proximal part of fibula. This imaginative procedure is clinical validated by its instant and explicit knee pain resorption and eventually deformity correction. The rationale of this treatment is named non-uniform settlement of the tibial plateau and used to elucidate the cause of knee joint degeneration, but cannot illuminate the reason of prompt postoperative pain resorption faithfully. To assist in better understanding of this therapeutic method and raising alert to possible unexpected complications, we proposed a new theory to elucidate the pain relief mechanism.
