Abstract
Category:Ankle ArthritisIntroduction/Purpose:To study the short-term effect of the INBONE II total ankle arthroplasty in the treatment of end-stage ankle arthritis, and to analyze the main operation points and complications.Methods:A total of 10 patients who used INBONE II for total ankle replacement in my Center from March 2016 to June 2017 were retrospective analyzed, including 2 patients who have a subtalar joint fusion at the same time. The VAS pain score and the American Orthopaedic Foot & Ankle Society (AOFAS) scores were used to evaluate the clinical efficacy.Results:All the patients were followed up, the average follow-up time was (12.80+-4.11) months (5-15 months), The AOFAS of preoperation was significantly higher (44.00+-4.06) vs (82.50+-3.17) score than that of the final follow-up, and VAS score was lower (6.80+-0.63) vs (1.60+-0.70) than that of the final follow-up (all P<0.01). There were 1 medial malleolus fracture, 1 lateral malleolus fracture intraoperation, 1 with symptomatic lateral malleolus osteophytes and lateral instability, which needs debridement, no superficial or deep infection was found,no prosthesis subsidence or malalignment and other complications was found.Conclusion:The short-term effect of total ankle arthroplasty using INBONE II prostheses for ankle end-stage arthritis is satisfactory, and further analysis was needed for its long-term efficacy and prosthetic survival rate.
