This paper aims to answer how current RTS guidelines for LAS compare to RTS protocols in elite sports teams; and how RTS decision-making after LAS can be optimised by connecting conceptual frameworks and real-life protocols. Elite teams’ protocols (n = 6) demonstrated large variability in RTS-phases, progression, and assessment strategies. Only one StARRT domain (specific tests) was universally assessed. All teams evaluated ankle range of motion, muscle function, jumping/hopping, and agility (PAASS framework). Psychological readiness, proprioception, contextual modifiers and ability to complete a full training were deficient in the protocols. Most protocols approached RTS with phases. Both literature and practice relied heavily on isolated tests, with minimal integration of sport-specific, continuous RTS assessments. Optimising RTS after LAS requires shifting from reductionist, single-time-point testing toward a complex-systems approach embedded across the RTS continuum. Clinicians should integrate progressive on-field rehabilitation, continuous monitoring across a broader range of factors influencing risk and readiness. Aligning frameworks with practical, phase-based protocols may enhance decision-making, reduce recurrence risk and facilitate return to performance.</div></div>","PeriodicalId":49698,"journal":{"name":"Physical Therapy in Sport","volume":"78 ","pages":"Article 101899"},"PeriodicalIF":2.2,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146173533","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Diagnostic performance analysis identified ΔT as the best single variable (AUC 0.83; sensitivity 78 %; specificity 78 %).
