BACKGROUND: The purpose of this study was to validate the possibility for preoperative self-efficacy of knee function measured by the Knee Self-Efficacy Scale (K-SES) to foresee patient outcome in terms of patient-reported outcome (PRO) scores at 2 years after an anterior cruciate ligament (ACL) reconstruction (ACLR). MATERIALS AND METHODS: This was a prospective study of cohort of 90 patients who underwent primary ACLR using hamstring tendon graft by a single team of surgeons over a period of 2 years at a government teaching tertiary care hospital. Demographic data (age and sex) and self-efficacy of knee function using K-SES were measured before surgery. Functional outcome were assessed using Tegner Lysholm Knee (TLK) Scoring Scale, Knee Injury and Osteoarthritis Outcome Score (KOOS), and International Knee Documentation Committee (IKDC) score at every scheduled follow-up after surgery. The mean of K-SES, TLK, IKDC, and KOOS scores was calculated. Pearson correlation coefficient was calculated to find out the relation between K-SES and the three knee subjective scores independently. Two-tailed test was used to compute the statistical significance of parameter deduced from data set. RESULTS: There was a strong positive correlation between K-SES and the three subjective scores independently. Two-tailed tests were statistically significant for all the three correlations. CONCLUSION: Evaluation of knee function using K-SES preoperatively is of predictive value for good functional outcome at 2 years after ACLR.
