New technique for knee flexion contracture with patella infera using patellar tendon reconstruction combined with anterior capsular shift: a case report

Abstract

A 24-year-old male presented with an open fracture of the left patella (Gustilo-Anderson grade III-A) and fracture of the left femoral lateral condyle, and subsequent patella alta suggesting rupture of the left patellar tendon. This initial injury was treated 6 months earlier in another hospital. He was referred because of limited knee motion and radiographs showed severe patella infera. By means of a combination of a contralateral BTB graft and soft tissue repair named anterior capsular shift, the knee contracture with patella infera was resolved successfully.
