Short-term Results of arthroscopic arthrodesis of Ankle with excessive varus deformity by complete deltoid release technique

Abstract

Abstract Purpose The objective of our study is to provide a better treatment option to patients with degenerative ankle deformities with varus of greater than 250 to achieve painless mobilization. Methods Our senior Surgeon performed arthroscopic fusion for varus ankle deformities of larger than 25 degrees in 64 of our patients. Prior to surgery, we managed our patients conservatively for a period of 6 months. Following surgery, we follow the patients for 6 up to 18 months. We used the curved curetteor and microfacture tool to release the deltoid ligament allowing us to fix larger degree of deformities. X-ray was used pre-operatively to assess the damage and deformity of the ankle and post operatively to assess the union during follow up. SPSS 17.0 windows software (Chicago,IL) was used for statistic to compare our group of patients with a groups of patients with ankle deformities of less than 25 0. The Wilcoxon Signed Rank (WSR) test was used for repeated measures. Categorical variables were compared using Fisher’s Exact (FE) test and the Mann–Whitney (MW) test was used to analyze pre-and postoperative AOFAS. We used the modified Mazur Grading System to evaluate the ankle union. Results The Union rate achieved in both Groups was ≥ 90%. Conclusion This technique is successful in treating varus ankle arthritis larger than 25 degrees.
