ARTHROSCOPIC SYNOVECTOMY OF THE KNEE - IS IT HELPFUL

We performed 211 arthroscopic synovectomies over a 10-year period. The results were assessed at follow-up of at least 2 years using the crit eria of pain, synovitis, and effusion, range of motion and function. I n rheumatoid knees (112 cases), we had good or excellent results in 80 %. However, in seronegative arthritides (32 cases), only 60% were succ essful. Pigmented villonodular synovitis was successfully treated with an 11% recurrence rate (19 cases total). Synovial chondromatosis (17 cases) had no recurrences. In patients with nonspecific synovitis or p osttraumatic synovitis, the synovitis was improved in 60% but only hal f the patients had pain relief and good function. Looking specifically at the posterior portals, there were five complications, all related to the posteromedial portal involving the saphenous nerve and vein. Ov erall excellent results can be achieved with due care and attention to detail.
