Long-term results of arthroscopic partial meniscectomy.

Detailed analysis of a series of 99 arthroscopic partial meniscectomies with a minimum follow-up time of 2.1 years (mean, 3 years; maximum, 4.5 years) showed that the spectacularly good early results were maintained in the longer term. Group I knees (67) had no previous surgery or ligamentous insufficiency, but those with chondromalacia were included. The remaining knees were designated Group II and analyzed separately. Group I showed 51.5% excellent and 39% good results, using criteria based on those of Tapper and Hoover. When only results in bucket handle tears were considered, 73% were excellent and 19% were good. Results in Group I also depended on the presence or absence of chondromalacia. Results in Group II were poorer than in Group I, but were still satisfactory in 67% of knees, although many had a torn anterior cruciate ligament of frank osteoarthritis. The arthroscopic technique should, where possible, become the standard method of treatment if patients require meniscectomy.
