SURGICAL VS CONSERVATIVE MANAGEMENT OF ANTERIOR CRUCIATE LIGAMENT (ACL) INJURY: A SYSTEMATIC REVIEW OF CLINICAL OUTCOMES
Bibliographic record
Abstract
Background: ACL injuries are among the most commonly studied knee injuries in orthopaedic and sports medicine. Despite decades of research, no clear consensus exists regarding the optimal treatment pathway-surgical reconstruction or conservative rehabilitation. To systematically review and compare the clinical outcomes of surgi Objective: cal versus conservative management of ACL injuries across diverse patient populations. A systematic search was conducted ac Methods: ross Ovid Emcare, Ovid MEDLINE, Embase, and Cochrane Library for studies published between 2015 and 2025. Inclusion criteria were RCTs, systematic reviews, and comparative cohort studies assessing outcomes of surgical versus conservative treatment for ACL injuries. Risk of bias and methodological quality were evaluated using the ROB 2.0 and Newcastle-Ottawa scales. Seventeen eligible studies we Results: re included. While surgical management demonstrated improved mechanical stability and higher return-to-sport (RTS) rates in athletic populations, conservative approaches yielded comparable long-term functional outcomes in non-athletes and those with partial tears. Surgery was associated with higher re-injury risk and longer recovery. Evidence quality was generally moderate, with significant heterogeneity across study designs and outcome measures. No one-size-fits-all approach exists for ACL injury management. Surgical intervention may Conclusion: be appropriate for highdemand individuals, whereas conservative rehabilitation can suffice for others. Shared decision-making, considering patient-specific factors and expectations, remains key. Further high-quality RCTs are warranted.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
