Chronic patella tendon rupture is a rare disabling injury that is technically difficult to repair. Bone avulsions of the patellar tendons or pure ruptures of the quadriceps and patellar tendons are usually caused by indirect forces and sometimes by penetrating injuries. We are presenting a case of old patella tendon rupture which also had other co morbidities of tibial fracture & partial patellectomy.This case had classic symptoms of old patella tendon rupture.We did repaired this case with help of semitendinosus & gracilis graft. Patient did recovered well in post operative phase with good physiotherapy. In most of cases old patella tendon rupture is associated with other systemic diseases or it is itself due to old neglected injury. In this case old rupture is associated with previous patella & tibia fractures with partial patellectomy.It shows that even after old partial patellectomy & old operated tibia fracture with interlocking nail,patella tendon can be repaired & patient can lead normal life.
