Editorial Commentary: Patellar Tendon or Hamstring: Which Kind of Anterior Cruciate Ligament Patient Are You?

Abstract

The role of graft selection on clinical and functional outcomes following anterior cruciate ligament (ACL) reconstruction has gained significant attention in the orthopaedic sports medicine community in recent years. Bone-patellar tendon-bone (BPTB) and semitendinosus/gracilis hamstring tendon (HT) autografts are 2 of the most commonly used grafts, given their low failure rates, predictable outcomes, and ability to incorporate appropriately at the graft site. However, multiple studies have recently shown each of these graft options to have some potentially less-desirable characteristics in regards to outcomes in specific patient populations. More specifically, in 14- to 25-year-old athletes, HT autografts have been shown to result in decreased rotational stability, decreased return to sport rates, and increased graft failure rates. On the other hand, BPTB autografts can require a prolonged recovery period and have been associated with increased postoperative pain and long-term kneeling pain. HT and BPTB grafts are both excellent grafts; however, it is important to understand the differences in clinical and functional outcomes between these graft options for ACL reconstruction. The characteristics of the graft need to be considered and individualized for each patient who is being treated for an ACL injury.
