Abstract
Purpose: Arthroscopic debridement and intraarticular hyaluronic acid injection are two treatment methods in the management of symptomatic middle-aged knee osteoarthritis. We combined these two methods for appropriate patients to strengthen the limited and temporary effect of arthroscopic debridement. Methods: We retrospectively reviewed of 38 patients who had early intraarticular hyaluronic acid injections after arthroscopic debridement. The average follow-up was averagely 16 months. The standard arthroscopic debridement performed in these patients. The treatment course continued of a series of three intraarticular injections of 2 ml sodium hyaluronate administered during 3 consecutive weeks beginning from first postoperative day. Results: Subjective pain scores were detected as meanly 8.8 for preoperative period and 2.3 for last control examination. Pain relief was established in all patients at 2.6 months meanly after the first injection. The Hospital for Special Surgery (HSS) knee scores increased from 67.1 before the procedure to 97.6 at the last follow-up examination. The last follow-up HSS knee scores of 28 (73.6%) patients were over 95. Conclusions: We support the combined use of both arthroscopic debridement and consequent three weekly intraarticular hyaluronic acid injections in patients with mild to moderate ostearthritis of the knee.
