Of 48 players with valid pre- and post-injury data, only 27.1% recovered to their pre-injury performance level. ATR independently increased the hazard of career termination by 68% (HR 1.68, 95% CI 1.18-2.39; <i>p</i> = .004), with injured players accruing 1.4 fewer active seasons over 10 years.</p><p><strong>Conclusions: </strong>ATRs in NFL players are associated with significant and persistent performance decline beyond natural career aging, despite a high RTP rate. Return to play does not equate to restoration of pre-injury performance or preservation of career longevity.</p><p><strong>Level of evidence: </strong>Level III, retrospective matched cohort study.</p>","PeriodicalId":51268,"journal":{"name":"Physician and Sportsmedicine","volume":" ","pages":"1-8"},"PeriodicalIF":1.8,"publicationDate":"2026-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148044660","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
