Limb Salvage Techniques Following Failed Total Ankle Replacement

Abstract

Catastrophic complications after total ankle replacement (TAR) is fortunately uncommon, but efforts to maintain limb length over higher-level amputations (i.e., below-knee or above-knee amputations) are indicated so that biomechanical performance is improved, prosthetic usage more compliant, and patient body image perception enhanced. Techniques for limb salvage include the use of ankle-level amputations, Ilizarov external circular ring fixation techniques, as well as local and free tissue transfers. Management of the failed total ankle replacement, especially those requiring soft-tissue coverage and limb salvage efforts, should only be performed by experienced surgeons and ideally in units where multidisciplinary support is available.
