Objectives:For patients with recurrent patellofemoral instability, tibial tuberosity medialization is commonly performed to reduce the lateral force applied to the patella by the patellar tendon. Medialization also alters the force acting on the tibia, which could alter tibiofemoral kinematics. Several other procedures are advocated to treat patellar instability, some of which are combined with medialization. The current study uses computational reconstruction of in vivo function to evaluate the influence of tibial tuberosity medialization on patellofemoral and tibiofemoral motion.
