Impact of patellofemoral osteoarthritis on long-term outcome of high tibial osteotomy and effects of ventralization of tibial tubercle

摘要

Medial compartment osteoarthritis (OA) of the knee frequently accompanies patellofemoral osteoarthritis (PF-OA). No consensus has been reached whether it is better to include treatment for the PF joint at the time of high tibial osteotomy (HTO), or if treatment of the PF joint is unnecessary. The purpose of this comparative retrospective study on medial compartment OA of the knee accompanying PF-OA was to examine the effects of PF-OA on the long-term outcome of HTO and to evaluate the significance of ventralization of the tibial tubercle when combined with HTO.
