Therapeutic effect of arthroscopic debridement combined with sodium hyaluronate injection on osteoarthritis of the knee

Objective To investigate therapeutic effect of arthroscopic debridement combined with sodium hyaluronate injection on osteoarthritis(OA) of the knee. Methods Arthroscopic debridement combined with intraarticular injection of sodium hyaluronate were performed on 59 patients with knee OA from September 2005 to January 2007 in our hospital. The patients were assessed by VAS pain score and Lysholm functional score during one-year follow-up. ResultsVAS pain score and Lysholm functional score were significantly improved compared with those before treatment. Neither severe complication nor side effect was observed during the period of treatment and follow-up. ConclusionsArthroscopic debridement combined with sodium hyaluronate intraarticular injection is an effective method for the treatment of osteoarthritis of the knee, but the indications should be grasped.
