Ninety patients, reconstructed with BTB or HS, were randomized using two initial graft tension protocols: (1) normal anteroposterior (AP) laxity (\u201clow-tension\u201d; n\u2009=\u200946) and (2) AP laxity overconstrained by 2\u2009mm (\u201chigh-tension\u201d; n\u2009=\u200944). Seventy-two patients had data available at 7 years, with 9 excluded for graft failure. Outcomes included the Knee Injury and Osteoarthritis Outcome Score, Short-Form-36 (SF-36), and Tegner activity scale. Clinical outcomes included KT-1000S and International Knee Documentation Committee examination score; and functional outcomes included 1-leg hop distance and peak knee extensor torque. Imaging outcomes included medial joint space width, Osteoarthritis Research Society International radiographic score, and Whole-Organ Magnetic Resonance Score. There were significantly improved outcomes in the high-tension compared with the low-tension HS group for SF-36 subset scores for bodily pain (p\u2009=\u20090.012), social functioning (p\u2009=\u20090.004), and mental health (p\u2009=\u20090.014) 84 months postsurgery. No significant differences in any outcome were found within the BTB groups. Tegner activity scores were also significantly higher for the high-tension HS group compared with the low-tension (6.0 vs. 3.8, p\u2009=\u20090.016). Patients with HS autografts placed in high tension had better outcomes relative to low tension for Tegner activity score and SF-36 subset scores for bodily pain, social functioning, and mental health. For this reason, we recommend that graft fixation be performed with the knee at 30-degree flexion (\u201chigh-tension\u201d condition) when reconstructing the ACL with HS autograft.<\/jats:p>","DOI":"10.1055\/s-0039-3402046","type":"journal-article","created":{"date-parts":[[2020,1,21]],"date-time":"2020-01-21T23:55:45Z","timestamp":1579650945000},"page":"777-783","source":"Crossref","is-referenced-by-count":6,"title":["Evaluation
