Comparative Effectiveness Review of Total Ankle Replacement: A Review of ReviewsDecember 28, 2017
Health Problem: End-stage ankle arthritis is characterized by severe arthritic ankle pain accompanied by a loss of ankle mobility and function that significantly interferes with daily activities and reduces quality of life.
Technology Description: Total ankle replacement (TAR) is one treatment option that involves surgical removal of the dysfunctional, painful ankle joint and replacement with a prosthetic device. TAR was developed as a method to relieve pain and restore joint function in patients with intractable disease resulting from conditions such as osteoarthritis, posttraumatic osteoarthritis, or rheumatoid arthritis.
Controversy: The significant drawbacks of ankle joint fusion led to the development of an alternative technique—the ankle prosthesis. While TAR was developed as an alternative to ankle arthrodesis (AA), it is a technically demanding procedure with a significant learning curve and may carry its own risks.
