Anterior cruciate ligament (ACL) tears are associated with the development of knee osteoarthritis in many patients despite ACL reconstruction surgery. However, little evidence is available to determine which patients will develop symptomatic knee osteoarthritis. To determine if preoperative outcome measures were associated with the future development of a symptomatic knee 7 years following ACL reconstruction. A secondary goal was to examine the relationship between imaging evidence of knee osteoarthritis and development of knee pain. Case control study Prospectively collected data from 72 subjects with 7 year follow-up after unilateral ACL reconstruction were reviewed. Subjects were divided into symptomatic and asymptomatic groups based on the previously defined Knee Osteoarthritis Outcome Score (KOOS) Pain score of ≤72. Demographic variables and preoperative KOOS and SF36 scores were compared between groups. Radiographic and magnetic resonance imaging data were used to evaluate differences in joint space width, OARSI radiographic score, and the Whole-Organ Magnetic Resonance Imaging (WORM) Score between groups. Univariate and multivariate analyses were performed to identify potential predictors of pain at 7 year follow-up. Wilcoxon Sum Rank and T-tests were used to compare imaging findings between the symptomatic and asymptomatic subjects at 7 years. Based on final KOOS Pain score, 7 of the 72 subjects available at 7 year follow-up formed the symptomatic group. No differences were found between groups in regards to demographic variables or intraoperative findings. In multivariate analysis, lower pre-operative KOOS Sports & Recreation (p=0.005) and lower pre-operative SF36 Mental Health (p=0.025) scores were found to be associated with a painful knee at 7 years, with increased odds of 82% and 68% per 10 unit decrease respectively. The WORM score at 7 years showed evidence of osteoarthritic changes in the symptomatic group compared to the asymptomatic group (p=.047). However, there were no significant differences in the OARSI radiographic score (p=.051) or joint space width (p=.488) between groups. Lower preoperative KOOS and SF36 scores were associated with those patients who developed symptomatic knee osteoarthritis 7 years following ACL reconstruction.
