[Treatment of a patient with patellar instability and lateral osteoarthritis of the knee joint under valgus limb deformity and low patellar position].

Abstract

Patients with patellar instability have one or more anatomical predispositions that are important in pathogenesis of this disease. We present treatment of a patient with valgus deformity of the lower limb and low patellar position with chronic instability. The patient underwent medial closing-wedge distal femoral osteotomy and transposition of tibial tuberosity.
