Abstract:
PURPOSE: To evaluate the clinical and radiological results and to analyze the survivorship after closing wedge proximal tibial osteotomy(PTO) using miniplate staple. MATERIALS AND METHODS: From November 1993 to August 2003, sixty closing wedge PTO using miniplate staple were performed in forty patients. The average follow-up period was 7.2 years(range, 2.8~12.5 years). According to the post- operative femorotibial angle(FTA), group I was defined as the cases whose FTA was less than 7 degrees of valgus(25 cases) and group II was defined as the cases whose FTA was more than 7 degrees of valgus(35 cases). The HSS score, FTA and survivorship were compared between group I and II. RESULTS: Average HSS score at the last follow up were 75.3 in group I and 85.9 in group II(p=0.006). Average FTA at the last follow up were 0.8 degrees in group I and 7.7 degrees in group II(p=0.006). The overall 7-year survivorship was 92.6% and 12-year survivorship was 75.5%. The 7-year survivorship and 12-year survivorship of group I were 86.7% and 54.2%, respectively. Group II have no failure at last follow up(p=0.0489). CONCLUSION: Our results suggest that the desirable postoperative FTA was more than 7 degrees of valgus, considering the long term satisfactory result and survivorship of the closing wedge PTO using miniplate staple for the osteoarthritic knees.
