ABSTRACT

Objective To analyze the outcomes of arthroscopy for secondary osteoarthrosis of the ankle joint. Methods From March 2000 to February 2006,62 patients with osteoarthrosis of the ankle joint were treated with arthroscopy in our department. Among the cases,52 received follow-up. We analyzed the therapeutic outcomes by evaluating the AOFAS,McGuire,and Mazur scores. Results The 52 cases were followed up for 12 to 84 months (mean,36.2 months). During the follow-up,we observed significantly increased scores of AOFAS,McGuire,and Mazur [postoperation vs. peroperation57.6?12.8,56.5?14.9,and 61.5?12.6 vs. 82.4?11.5 (t=11.02,P=0.00),84.8?12.6 (t=9.52,P=0.00),and 84.1?14.7 (t=8.70,P=0.00)] with the rate of excellent and good results of 80.8% (42/52),82.7% (43/52),and 84.6% (44/52).Conclusions Arthroscopic treatment is effective for osteoarthrosis of the ankle joint with satisfactory results especially in patients with mild or moderate osteoarthrosis or those with loose bodies.
