Patellar tendon disruption is one of the most dreaded complications after total knee arthroplasty (TKA) impacting joint function and implant longevity. Management of this condition remains controversial, and no one treatment has provided consistent clinical success. Here we propose a modified technique from the standard Achilles allograft procedure to reconstruct a ruptured patellar tendon after TKA. A fresh-frozen Achilles tendon allograft with attached calcaneal bone graft was used. Our technique offers the advantage of a more stable graft fixation by relying on both quadriceps tendon and transosseous patellar fixation and bone-to-bone allograft fixation to the tibial tuberosity.
