Arthroscopic surgery is commonly used to address meniscal damage in the knee. However, research over the past two decades has questioned its value in patients with osteoarthritis of the knee.
A study published in the New England Journal of Medicine (September 11, 2008; 359(11):1097–1107) examined outcomes in patients with moderate to severe knee osteoarthritis. In this randomized trial, one group of 86 patients underwent arthroscopic surgery in addition to physical therapy and medical management, while a second group of 86 patients received physical therapy and medical management alone, without surgery.
When outcomes were assessed two years later, there were no significant differences between the two groups in symptom severity or quality-of-life measures. Patients who did not undergo arthroscopic surgery experienced outcomes comparable to those who received surgery.
These findings were consistent with earlier research published in the New England Journal of Medicine (July 11, 2002; 347(2):81–88), which also reported no meaningful advantage of arthroscopic surgery over non-surgical management for osteoarthritis-related knee symptoms.
Together, these studies suggest that in patients with knee osteoarthritis, arthroscopic surgery may not provide additional long-term benefit beyond conservative therapy.
