“…Bearing movement on the tibia indicates that the rolling element of the natural movement of the talus on the tibia [11,33,34] is reproduced. We found no mention of bearing movement in any of the reports of the current three-component devices with anatomic talar and flat tibial components [3,6,7,25,30,31,[50][51][52][53][54]. The overall AOFAS score improved by a mean of 40.5 points (38.5 preoperatively to 79.0 at 48 months) and was similar to the 45-point increase of the meta-analysis [48].…”

“…1) showed that to achieve ligament compatibility, either both fixed articular surfaces should have anatomic shapes or both should be nonanatomic [33,34]. Current three-part prostheses [3,6,7,25,30,31,[50][51][52][53][54] use a more or less natural-like convex surface for the talar component and a nonanatomic flat surface for the tibial component. We have shown this combination of anatomic and nonanatomic surfaces cannot reproduce isometricity of ligaments and therefore cannot be compatible with normal ligament function [33,34].…”

Background A three-part ankle replacement was developed to achieve compatibility with the natural ligaments by allowing fibers on the medial and lateral sides to remain isometric during passive motion. Unlike all current prostheses, the new design uses nonanatomically shaped components on the tibia and talus and a fully conforming interposed meniscal bearing.Questions/purposes Does this new design restore ankle mobility, improve clinical score, and result in low complication and early revision rates? Patients and Methods We reviewed 51 patients in whom 51 prostheses were implanted in a seven-center trial from July 2003 to July 2006. The mean age of the patients at surgery was 61.5 years (range, 35.1-82.5 years). We used the AOFAS score to assess clinical outcome. We used lateral radiographs to assess function. The minimum followup was 24 months (mean, 30 months; range, 24-48 months). Results The mean preoperative AOFAS score of 38.5 increased to 76.9, 79.1, 76.4, and 79.0 at 12, 24, 36, and 48 months, respectively. We observed a correlation between meniscal bearing movement on the tibial component (mean, 3.4 mm; range, 2-12 mm) and range of flexion at the replaced ankle (mean, 27.48; range, 168-538). We revised one arthroplasty in the second postoperative year for lateral impingement, providing a 3-year cumulative survival rate of 97% and performed one other secondary operation for hindfoot pain. Conclusions These data suggest the new prosthesis can provide short-term restoration of ankle mobility, a good clinical score, and low complication and failure rates. Longer followup with larger numbers is required.

“…Despite high numbers of failures in early generations of total ankle arthroplasty (TAA), a continued and increasing interest in the use of these devices for end-stage arthritis as an alternative to arthrodesis of the ankle exists [1][2][3][4][5]. However, while some studies report encouraging mid-term results, the rate of complications after TAA is high compared to total hip and knee replacement [6][7][8][9][10].…”

Introduction Total ankle arthroplasty is increasingly used as an alternative to arthrodesis to treat advanced ankle arthritis. However, the outcomes and postoperative complications are poorly described. Patients and methods Between March 2005 and May 2010 114 S.T.A.R. prostheses were implanted by one surgeon at our institution. We retrospectively analysed the demographics, clinical outcomes and radiographic characteristics of 100 ankle prostheses (97 patients).Results The average follow up was 36 months. The average preoperative AOFAS score of 36.87 (22-58) significantly increased to 75.99 postoperative. A total of 87 % of the patients reported a better life quality. Twenty-seven ankles incurred complications after primary surgery, and 21 prostheses required revision surgery, including four patients who required arthrodesis. Conclusion Our study shows a high satisfaction rate after total ankle replacement and clear pain relief. Patients with a body mass Index higher than 30 showed a higher rate of complications. Compared with ankle fusion, the rates of complications are comparable.
