Rupture of the patellar tendon following TKA is fortunately an uncommon complication with an incidence of 0.2-4% (Abril et al, 1995), Numerous options have been reported for treating this complication, including primary suture into a bone trough (Abril ct al, 1995), autogenous tendon transfer (Cadambi and Engh 1992), and use of an artificial ligament (Fujikawa et al, 1994), Allograft patellar tendon has also been utilized either retaining the host patella and using a bone-tendon-bone graft or excising the host patella and using a quadriceps tendon-patella patellar tendon-tibial tubercle graft (Emerson et al, 1990, Emerson et al, 1994, Zanotti et al, 1995, Booth ct al. 1999), All of these techniques require structural integrity of the proximal tibia in the area of the tibial tubercle in order to attach the repair or graft to restore continuity of the extensor mechanism. When there is massive osteolysis and bone loss involving the proximal tibia, the situation becomes more complex and the previously described techniques are not advisable, In such cases, function can be obtained with a composite allograft of proximal tibia-patellar tendon-patella-quadriceps tendon, We describe a technique for dealing with this difficult clinical situation.
