AbstractDue to the change in the age structure in Germany and the steadily increasing number of fractures, arthrosis of the upper ankle joint, mainly caused by posttraumatic conditions, is becoming more and more relevant in routine trauma surgery and orthopedics. Patients suffer from reduced functionality and quality of life as well as immobilizing pain. In addition to an ankle joint prosthesis arthrodesis of the upper ankle joint offers an alternative for the treatment of advanced arthrosis. When performing an arthrodesis there is basically the option of both open and arthroscopic procedures to prepare the joint and remove the cartilage. In both procedures the upper ankle joint is usually fixed with 2-3 cannulated compression screws. Comparative studies to date have shown an advantage of the arthroscopic technique in terms of complication rate, length of hospitalization, proportion of ossification and functional outcome. The indications for arthroscopic fusion should be strictly considered, especially in the case of malalignment, as major axis corrections are difficult to perform. In such cases, open fusion of the upper ankle joint still seems superior to the arthroscopic method.© 2022.
