Incidence of revision after primary implantation of the Scandinavian Total Ankle Replacement system: a systematic review.

Total ankle replacement was initially popularized in the 1970s as an alternative to ankle arthrodesis for advanced ankle arthritis; however, failures were catastrophic. Current implants show promise, focusing on normal joint anatomy and function with greatly improved materials and more precise surgical technique. Nevertheless, even with advancements in technology and implant engineering, implant failure remains a problem. Debate has existed and published reports vary greatly concerning the incidence of failure and revision of the Scandinavian Total Ankle Replacement system. Thus, a systematic review was performed revealing a 10.7% revision rate at weighted mean follow-up of 64 months.
