| Abstract |
Total ankle replacement has become a valuable treatment option for end-stage osteoarthritis in recent decades. The most recent generation of implants comprises a second interface between the polyethylene insert and the tibial prosthesis component. To date, no data are available indicating the interindividual difference in the relative position of talar and tibial implant components and their position change over time. We assessed the radiographs of 368 ankles that underwent primary arthroplasty with a HINTEGRA ankle to determine the spatial relationship between talar and tibial components at the time of surgery and during followup. Examination of the data suggests that the latest three-component prosthesis functions similar to the two-component prosthesis, but with an added advantage of allowing an individualized position of the polyethylene insert in response to the individual soft tissue load. |
