Abstract:
PURPOSE: To evaluate the clinical results of arthroscopic debridement in osteoarthritic ankle and prognostic factors. MATERIALS AND METHODS: Between Feb. 2001 and Mar. 2004, twenty-seven patients who had an osteoarthritic ankle disease were managed by arthroscopic debridement. The mean age of the patients was 50.0 years (20-71) and the mean follow-up after operation was 16.2 months (12-36). There were 18 men (66.7%) and 9 women (33.3%). The preoperative radiographic findings were divided into 4 groups according to the classification system by Takakura et al. Preoperative AOFAS ankle-hindfoot scale and subjective satisfaction were checked at the last follow-up visit, and the results were compared. RESULTS: In radiological evaluation, stage I was 6 cases (22.2%), stage II was 14 cases (51.9%), stage III was 4 cases (14.8%), and stage IV was 3 cases (11.1%). The mean preoperative AOFAS ankle-hindfoot scale was 59.1+/-16.7 and improved to 66.5+/-24.3 at last follow-up. Especially, in stage I, preoperative AOFAS score was 69.3+/-18.7 and improved to 74.3+/-29.7, and in stage II, preoperative AOFAS socre was 63.0+/-9.6 and improved to 77.1+/-12.9. But in the stage III and IV, preoperative scores were not improved. The preoperative radiographic findings correlated with the outcome at the last follow-up time (p<0.05). The group with loose body and the group without anterior osteophyte showed better AOFAS score compared to the control group, but there was no statistically significant difference between the two-groups. In subjective satisfaction, excellent or good results were achieved in 14 cases (51%). CONCLUSION: We suggest that arthroscopic debridement is an effective treatment in which preservation of alignment and reasonable articular cartilage can be achieved.
