This study was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and Meta-Analysis of Observational Studies in Epidemiology (MOOSE) guidelines. All studies in PubMed and Embase that reported functional knee parameters and patient-reported outcomes after ACL reconstruction with ST and ST-G grafts independently were included in the review. Selected end points for random effects, pairwise meta-analysis included side-to-side deficit (%) in isokinetic peak torque, peak torque ratio (%), side-to-side difference (mm) in anterior laxity, and patient-reported outcome scores at minimum 2-year follow-up. A total of 15 primary references comprising 1,109 participants were identified. The ST group had decreased side-to-side deficit in isokinetic peak torque when compared with the ST-G group for flexion at 60 degrees\/s (p\u2009=\u20090.02) and 180 degrees\/s (p\u2009=\u20090.01) at 2-year follow-up. There were no significant differences in side-to-side difference in anterior laxity (p\u2009=\u20090.81), hamstring\/quadriceps peak torque ratios at 60 degrees\/s (p\u2009=\u20090.83) and 180 degrees\/s (p\u2009=\u20090.36), and patient-reported outcomes in the International Knee Documentation Committee score (p\u2009=\u20090.06) and Lysholm score (p\u2009=\u20090.67). The addition of the gracilis tendon to the hamstring autograft in ACL reconstruction results in increased side-to-side deficits in isokinetic peak flexion torque. However, patient-reported outcome scores and knee laxity measurements are comparable with those of ST grafts.<\/jats:p>","DOI":"10.1055\/s-0038-1669950","type":"journal-article","created":{"date-parts":[[2018,9,12]],"date-time":"2018-09-12T00:09:48Z","timestamp":1536710988000},"page":"796-803","source":"Crossref","is-referenced-by-count":17,"title":["Arthroscopic Anterior Cruciate Ligament Reconstruction: A Meta-Analysis Comparing Semitendinosus Alone and Semitendinosus with Gracilis Tendon Autografts"],"prefix":"10.1055","volume":"32","author":[{"given":"Brian Zhaojie","family":"Chin","sequence":"additional","affiliation":[{"name":"University Orthopaedics, Hand and Reconstructive Microsurgical Cluster, National University Health System, Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ian Jun Yan","family":"Wee","sequence":"additional","affiliation":[{"name":"University Orthopaedics, Hand and Reconstructive Microsurgical Cluster, National University Health System, Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nicholas Li-Xun","family":"Syn","sequence":"additional","affiliation":[{"name":"University Orthopaedics, Hand and Reconstructive Microsurgical Cluster, National University Health System, Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lingaraj","family":"Krishna","sequence":"additional","affiliation":[{"name":"University Orthopaedics, Hand and Reconstructive Microsurgical Cluster, National University Health System, Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2018,9,11]]},"container-title":["The Journal of Knee Surgery"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/www.thieme-connect.de\/products\/ejournals\/pdf\/10.1055\/s-0038-1669950.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,8,5]],"date-time":"2019-08-05T06:00:00Z","timestamp":1564984800000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.thieme-connect.de\/DOI\/DOI?10.1055\/s-0038-1669950"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,9,11]]},"references-count":0,"journal-issue":{"issue":"08","published-online":{"date-parts":[[2019,8,2]]},"published-print":{"date-parts":[[2019,8]]}},"URL":"https:\/\/doi.org\/10.1055\/s-0038-1669950","relation":{},"ISSN":["1538-8506","1938-2480"],"issn-type":[{"value":"1538-8506","type":"print"},{"value":"1938-2480","type":"electronic"}],"subject":[],"published":{"date-parts":[[2018,9,11]]}}}
