Abstract

|
Although first generation total ankle replacement (TAR) had high failure rates, recent investigations have reported good results of the newer generations of TAR due to advances in implant designs and techniques. Patient selection is critical to performing TAR to obtain promising outcomes and to decrease complication rate. As the current concepts of correcting the accompanying deformity have been established, TAR in moderate to severe varus deformity of the ankle result in favorable outcomes and indications for TAR are expanding. Correction of deformity and hindfoot fusion should be performed in conjunction with TAR if needed. If radiolucency around components or osteolysis is progressive during follow-up, CT should be carried out as a confirmative diagnostic method. TAR is an effective treatment modality alternative to ankle fusion. However, we should recognize that TAR is a demanding procedure, which requires accurate techniques, enough experience, and preoperative plan for a concomitant deformity.
