Outcome of chronic isolated anterior cruciate ligament reconstruction.

摘要

The aim of the article is to identify demographic and intraoperative factors that predict patient-oriented outcomes as measured by knee-specific and general quality of life (QoL) questionnaires for chronic, unilateral primary anterior cruciate ligament (ACL) tears following surgical reconstruction. A total of 69 patients were prospectively evaluated using the Medical Outcomes Study 36-item Short Form (SF-36), modified Lysholm, Tegner activity level, and subjective portion of the International Knee Documentation Committee (IKDC) questionnaires. The surveys were administered preoperatively and postoperatively with a minimum 2-year follow up. Efficacy of treatment was evaluated by comparing preoperative and postoperative questionnaire scores. Multivariate linear regression analysis was used to identify demographic and intraoperative variables that were independent predictors of outcome. At a minimum 2-year follow-up (mean, 3.6 years), 55 of 69 patients (80%) were available for follow-up. There were statistically significant improvements in the Lysholm, Tegner, and subjective portion of the IKDC, as well as several SF-36 domains that measure physical capabilities (p?
