Abstract
Objectives
To evaluate the clinical outcomes following medial collateral ligament (MCL) reconstruction using a double-bundle triangular tibial-sling technique, with a minimum 2-year follow-up.
Methods
This multicenter prospective cohort study included patients undergoing primary MCL reconstruction between 2020 and 2022. Patient-reported outcomes (Lysholm, IKDC subjective, and Tegner) were assessed preoperatively and at final follow-up (≥24 months). Statistical significance was evaluated using paired tests, and clinical relevance was quantified with distribution-based thresholds (0.5 SD, SEM, and MDC₉₅). Objective valgus stability at 0° and 30° of knee flexion was graded and compared using objective IKDC criteria pre- and postoperatively. Multivariable logistic regression was performed to identify independent predictors of failure to restore normal valgus stability.
