Low correlation between functional performance and patient reported outcome measures in individuals with non-surgically treated ACL injury

Describe a consecutive cohort of people with non-surgically treated ACL injury and evaluate correlations between functional performance patient reported outcome measures (PROMs). Cross-sectional. Sixty-eight individuals (38 males, 18–45 years old) 2–5 after injury. Tegner Activity Scale, International Knee Documentation Committee Subjective Form (IKDC-SKF), Anterior Cruciate Ligament Return to Sport Injury scale (ACL-RSI) ACL-Quality Life (ACL-QoL) were completed. Functional was assessed using 4 hop tests squat test. Mean IKDC-SKF score 72 ± 17 mean LSI on above 90%. Scale reduced from median 8 pre-injury 5 at follow up. Satisfaction activity level 7 10-point ordinal scale. Correlations moderate strong (r = 0.552–0.856) PROMs, negligible weak 0.003–0.403) PROMs 0.142–0.683) tests. had or correlation which indicates the need for multi-modal assessment strategies. injury, but most patients able resume physical sufficient maintain health displayed symmetrical performance.
