Abstract
The ankle joint has to bear the entire body weight on arelatively small joint surface. Incongruities, instabilities and deformities lead to painful arthrosis and considerable restrictions in everyday life. For many years, arthrodesis has proven to be the gold standard for end stage arthrosis; however, considering modern endoprostheses for the ankle joint it is no longer appropriate to offer only arthrodesis. The very good results of the 3rd generation 3‑component prostheses and the 4th generation 2‑component prostheses show how much the surgical treatment options for the ankle joint are currently changing. The simplified implantation techniques enable access to arthroplasty of the ankle joint for abroader spectrum of surgeons and explain the increasing implantation rates in recent years. Decisive for postoperative success are correct planning with knowledge of the leg axes and foot position, correct patient selection and exact surgical placement of the components.
