Chronic rupture of the extensor apparatus of the knee joint

Chronic ruptures of the extensor mechanism of the knee are uncommon injuries, and previously reported literature assumes the presence of an intact patella for repair. We present a case of chronic rupture following patellectomy done twelve years previously. The defect in the extensor apparatus was extensive (18cm), and this was bridged using a large fascia lata graft from the opposite thigh, with reasonably successful results.
