Chen H, Liu H, Chen L, et al. - Researchers sought to compare patellar tendon (PT) autografts with 4-strand semitendinosus and gracilis (STG) autografts regarding knee stability, functional outcomes, as well as complications after anterior cruciate ligament (ACL) reconstruction at minimal follow-up of 5 years. Searching PubMed, Embase, and the Cochrane Library, they identified nine clinical studies with 630 patients (313 PT and 317 STG autografts) for inclusion in this work. Except that the STG group had less anterior knee pain, comparable results were noted of PT autograft to 4-strand STG autograft in terms of knee stability and functional outcomes after ACL reconstruction with mid- to long-term follow-up. Furthermore, there was no statistically significant difference in loss of ROM, kneeling pain, graft re-rupture rate, revision rate, and OA change.
