Patellar Tendon Versus Quadrupled Bone–Semitendinosus Anterior Cruciate Ligament Reconstruction: A Prospective Clinical Investigation in Athletes

Purpose: Patellar tendon and hamstrings are both used in anterior cruciate ligament (ACL) reconstruction, and comparisons have been reported with different results. The purpose of this clinical study was to compare the results of ACL reconstruction in athletes with 2 different graft types, both using bone-to-bone healing: bone–patellar tendon–bone graft and a quadrupled bone–semitendinosus graft.
