Participants were again asked about graft preferences. Participants were asked whether they would change their preference based on surgeon recommendation and what factors influenced their decisions. Statistical analysis was performed using Shapiro-Wilks test to determine normality, and Student paired <i>t</i> test was used for comparison.</p><p><strong>Results: </strong>There were 491 participants with a mean age of 39.9 (range, 19-72). Before participant education regarding graft types, 19.3% preferred bone-patellar tendon-bone (BPTB), 18.7% preferred quadriceps tendon (QT), 12.6% preferred hamstring tendon (HT), and 53.4% had no preference. Following education, a significantly greater number of participants chose each graft type; 37.7% (<i>P</i> < .01) preferred BPTB, 21.6% (<i>P</i> < .01) preferred QT, and 13.8% (<i>P</i> < .01) preferred HT. Significantly fewer participants had no preference (26.9%; <i>P</i> < .01). Among the most important factors in patient preference was surgeon preference (n = 357; 72.7%), as 424 (86.4%) participants said they would switch their graft preference if their surgeon recommended it.</p><p><strong>Conclusion: </strong>The findings of this study imply that informed patients can participate in medical decision making with respect to their graft choices in ACLR and that providing educational information can help surgeons and patients work together to optimize patient care.</p>","PeriodicalId":19646,"journal":{"name":"Orthopaedic Journal of Sports Medicine","volume":"13 8","pages":"23259671251362631"},"PeriodicalIF":2.5,"publicationDate":"2025-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12397566/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144963551","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
