To date, surgeons have not convincingly shown that a total ankle replacement (TAR) will prevent the progression of peritalar arthritis, possibly because in many series, patients undergoing TAR have concomitant degenerative changes in the subtalar joint. Several studies have reported the progression of subtalar or talonavicular arthritis after TAR, while others have noted no development of subtalar arthritis, although at a relatively short time interval from the TAR. These studies suggest that total ankle replacement does not fully protect the adjacent hindfoot from the development or progression of arthritis. This may be due to concomitant pre-existing degenerative changes in the hindfoot joints. Therefore, it is necessary to perform hindfoot fusions concurrently or after a TAR. This review will summarize the current literature.
