Role of gracilis harvesting in four-strand hamstring tendon anterior cruciate ligament reconstruction: a double-blinded prospective randomized clinical trial

摘要

Weakness in knee flexion following anterior cruciate ligament (ACL) reconstruction is one of the key issues in the treatment of an ACL tear. The purpose of this study was to examine and compare clinical outcome measures of ACL reconstruction using semitendinosus autograft (ST) versus semitendinosus + gracilis (ST/G) reconstructive techniques.
