ABSTRACT
Proper alignment and sizing are critical to the performance of a successful total ankle arthroplasty. While it is common practice in preoperative planning prior to total knee and total hip arthroplasty, preoperative computer templating has not been well established in the setting of total ankle arthroplasty. A retrospective review of all total ankle arthroplasties performed during a 10-year period by a single fellowship-trained orthopaedic surgeon was conducted. Computer templating was utilized for all preoperative Anterior to Posterior (AP) and lateral standing radiographs, and templated component sizes were compared to the operative reports and postoperative radiographs to determine the precision of the available templates. Statistical analysis was performed with Interclass Correlation Coefficients (ICC) and descriptive statistical tests. Seventy patients with a mean age of 64.8 years (range, 48-87) and mean BMI of 30.34 (range, 19.1-55.6) were included. The ICC demonstrated that both the AP (ICC 0.80 - 95% CI 0.679-0.876) and lateral (ICC 0.786 - 95% CI 0.655-0.867) radiographs provided accurate tibial total ankle arthroplasty component templating. Similarly, the AP (ICC 0.842 - 95% CI 0.745-0.902) and lateral (ICC 0.809 - 95% CI 0.692-0.881) radiographs provided accurate talar templating. No differences were observed when comparing AP to lateral radiographs in percentage of correct component templating tibial AP 61.4% vs lateral 58.6%, p = .119 and talar component AP 57.1% vs lateral 45.7%, p = .176. These study findings demonstrate that preoperative templating for total ankle arthroplasties is accurate in determining appropriate implant sizing. Accurate templating is an absolute necessity for future templating studies.
