TOTAL ANKLE PROSTHESIS: RETROSPECTIVE ANALYSIS OF A CONTINUOUS AND HOMOGENEOUS SERIES OF 26 CASES WITH 5–12 YEARS FOLLOW-UP
2018
Purpose: The purpose of this work was to evaluate the mid-term clinical and radiological outcome of a homogeneous and continuous series of third-generation total ankle prostheses (resurfacing, cylindric, noncemented, triple-compartment).Material and methods: From March 1990 to June 1996, 26 patients aged 57 years (32–73) were treated with a New Jersey LCS (n=5) or Buechel-Pappas (n=21) prosthesis. Most of the patients (n=21) had a posttraumatic ankle. Preoperatively, mean ankle motion was 17°. The AOFAS score was used for the clinical assessment. The position of the prosthesis and its stability over time were assessed on the x-rays together with the insert, the bone-prosthesis interface, the bone structure and periprosthetic ossifications.Results: Intra and postoperative complications were malleolar fracture (n=5), haematoma (n=1), late wound healing (n=1), insert instability (n=2), and medial malleolar conflict (n=1) requiring reoperation with preservation of the implant. At mean follow-up of seven years...
