Abstract: Extensor Mechanism Injuries of knee are rare. True incidence of traumatic Patellar tendon rupture is unknown but is third in sequence after neglected Patellar fracture and quadriceps tears. Often the diagnosis or treatment of such cases are delayed, hence the biggest challenge here is to the need to bridge the gap caused by the contracted quadriceps muscle or the patellar tendon. i.e. Patella baja in quadriceps rupture and Patella alta in patellar tendon rupture. The goal of treatment is to bring down the displaced fragment and maintain its position by lengthening the contracted tissue and restore the Extensor mechanism through a bone to bone or a tendon to bone repair.
We have treated 2 cases of delayed presentation of Extensor mechanism Injuries. The first case was a 40-Y-M with patella non union and the second case a 35-Y-M was a Left tibial plateau fracture (type -2) with ruptured Patellar tendon and associated ligamentous injuries. Both the patient were managed by reconstructing the Extensor mechanism.
