【 摘 要 】

Category:AnkleIntroduction/Purpose:Total ankle arthroplasty (TAA) is the alternative to tibio-talar fusion in the non-conservative operative treatment of osteoarthritis. It preserves joint range of motion and prevents adjacent joints while improving quality of life and relief.Long-term studies frequently show the presence of periprosthetic cysts, which is linked to an increased risk of revision, pain or lameness.In 2012, a stainless steel, DLC coated, TAA was subjected to a clinical review and a CT scan analysis. The main objective of this study was to analyze periprosthetic cysts evolution (numbers and volumes) on helical CT scans at 4 years apart of this same cohort of patients.The secondary objective was to present clinical results and survival curve of the implant.Methods:We retrospectively reviewed the cohort of 68 cases from 2012. The average follow-up was 13 ± 6 years. 42 CT analysis of the Periprosthetic cysts, were performed at the last follow-up and compared to the 2012 analysis. Cysts were clas...
