The influence of hamstring autograft size on patient-reported outcomes and risk of revision after anterior cruciate ligament reconstruction: a Multicenter Orthopaedic Outcomes Network (MOON) Cohort Study.

摘要: Purpose The purpose of this study was to evaluate the effect graft size on patient-reported outcomes and revision risk after anterior cruciate ligament (ACL) reconstruction. Methods A retrospective chart review prospectively collected cohort data performed, 263 320 consecutive patients (82.2%) undergoing primary ACL reconstruction with hamstring autograft were evaluated. We recorded size; femoral tunnel drilling technique; patient age, sex, body mass index at time reconstruction; Knee Injury Osteoarthritis Outcome Score (KOOS) International Documentation Committee score preoperatively 2 years postoperatively; whether each underwent during 2-year follow-up period. Revision used as a marker for failure. relation between determined by multiple linear regression. dichotomizing 8 mm stratifying age. Results After we controlled operative side, surgeon, index, choice, technique, 1-mm increase in noted correlate 3.3-point KOOS pain subscale ( P  = .003), 2.0-point activities daily living .034), 5.2-point sport/recreation function .004), 3.4-point subjective .026). required 0 64 (0.0%) grafts greater than diameter 14 199 (7.0%) or smaller .037). Among aged 18 younger, 13 71 (18.3%) smaller. Conclusions Smaller is predictor poorer larger sample confirm Level Evidence III, comparative study.
