Although arthroscopic meniscal surgery is one of the most common surgical interventions, the theory that served as basis for this procedure has been questioned. Several studies have found meniscal tears in asymptomatic knees in different populations, and therefore the idea that meniscal tears are the cause of symptoms and that addressing the tear during surgery is the solution is no longer a sure thing.
In this study, 443 patients who underwent arthroscopic surgery for a meniscal tear were included. Before the surgery, they completed an online version of the Knee Injury and Osteoarthritis Outcome Score (KOOS). The subscales for pain, function in sports and recreation, and function in daily living were selected as primary outcome measures.
The surgeon who performed the procedure logged objective signs of knee pathologies according to a modified version of the International Society of Arthroscopy Knee Surgery and Orthopaedic Sports Medicine (ISAKOS) classification. The information that was documented included tear characteristics, cartilage grade, presence of plica and joint laxity. Supplemental information was taken from the patients’ surgery reports.
