Ankle Arthroplasty

Abstract

There are numerous types of arthroplasty implants available for the ankle. In my opinion, six prostheses will be in widespread use for the mid-term future. Two-component prostheses are of no importance in Europe. There are two types of three-component prostheses: an onlay type and a «talar cap» type, with differences in tibial and talar fixation. The main problem today is the appearance of periprosthetic cysts. In my opinion, this is due to primary instability of the (mini-) interface, which leads to increasing bone resorption. This is less common with «cap» prostheses, so I have returned to my initial use of the STAR prosthesis. A substantial improvement in the instruments was also a deciding factor. If the guidelines are followed, successful implantation is possible for the experienced surgeon.
