The efficacy of arthroscopic surgery for the treatment of moderate osteoarthritis of the knee

Abstract

Objective To identify the effectiveness of arthroscopic debridement(AD) in moderate knee OA on pain and function. Methods 87 patients with moderate degenerative osteoarthritis of knees diagonocised according to ARA,were randomly assigned to two groups:43 patients in therapy group were subjected to AD in combine with sodium hyaluronate injection and physiotherapy,44 patients in the control group only received so-dium hyaluronate injection and physiotherapy. The relief of joint pain, swell, fluidity, and the improvement of joint range of motion before and after the treatment were evaluated by score of Lysholm. Results There is no si-ganificant different between in the therapy group and the control group in the score of Lysholm(P<0.05). Con-clusion The sodium hyaluronate injection combined with physiotherapy can relieve clinical symptoms and im-prove joint function in the patients with moderate degenerative osteoarthritis of knees, arthroscopic surgery for moderate osteoarthritis of the knee provides no additional benefit to optimized physical and HA therapy.
