Arthroscopy update #6. Arthroscopy in the osteoarthritic knee. Long-term follow-up

A retrospective review was performed of 109 patients who underwent arthroscopic debridement of the knee for degenerative osteoarthritis. The results were evaluated using a modification of the Hospital for Special Surgery (HSS) scoring system as well as a subjective scale that measured the patients' degree of satisfaction with the procedure. Follow-up was obtained in 111 knees for an overall follow-up of 92% of knees. The mean age of the patients was 58.1 years, and the mean follow-up was 50.6 months. The overall results were 50 good, 20 fair, and 41 poor. Arthroscopic debridement offered measurable relief for 63% of the patients for a significant period of time. Although the results are equivocal by orthopaedic standards, 74% of the patients felt the procedure had been beneficial.
