Anatomical reconstruction of the patellar tendon: a new technique with hamstring tendons and iliotibial tract.

Abstract

A new technique of patellar tendon reconstruction was performed in a patient who lost tendon and tibial tuberosity during wide excision surgery for a malignancy. In this procedure, the tendon was anatomically replaced by a graft composed of ipsilateral hamstring tendons and iliotibial tract, with the biomechanical conditions considered. Both ends of the graft were secured in the size-matched bone tunnels in the patella and tibia by screw post fixation, which is a technique established in ligament reconstruction surgery in the knee joint. At the twenty-month follow-up, the result was deemed successful.
