Quadriceps Tendon Allograft for Posterior Cruciate Ligament Reconstruction With and Without a Bone Block.

Abstract

Graft options for posterior cruciate ligament reconstruction include both autografts and allografts, with hamstring autografts and Achilles tendon allografts being the most common options. Although not as utilized, quadriceps tendon allografts have advantages similar to those that have driven the use of quadriceps autografts in knee reconstruction, such as favorable biomechanical properties and increased cross-sectional area. This article describes the use of quadriceps tendon allograft with bone block and without bone block for posterior cruciate ligament reconstruction. Surgical techniques, fixation methods, and clinical indications of each graft are discussed, as well as the pearls and pitfalls of each technique.
