Scientists have found that patients are able to perform sports-related functions and maintain high knee-related quality of life 10 years after anterior cruciate ligament (ACL) reconstruction surgery, although activity level declines over time.
For the study, which is the first prospective ACL reconstruction cohort with over 80 per cent follow-up at 10 years, the authors identified and enrolled patients with unilateral ACL reconstruction between 2002 and 2004. Patients were followed at a minimum of two, six, and 10 years post-op.
Marx activity level scores dropped markedly over time, from a median score of 12 points at baseline to 6 points at 10 years. Both International Knee Documentation Committee Subjective Knee Form (IKDC) and Knee injury and Osteoarthritis Outcome Score (KOOS) scores significantly improved after two years and were maintained at six and 10 years. These improvements were noted across a substantial population of 1,320 patients, who made up 83 per cent of the original study group.
The authors say the prognostic information will “undoubtedly aid physician counselling of patients’ expectations after ACL reconstruction at surgery and at two and six years to predict 10 year outcome”.
The findings were presented at the American Orthopaedic Society for Sports Medicine’s Annual Meeting .
