Outcomes of Ankle Arthrodesis Conversion to Total Ankle Arthroplasty: A Systematic Review.

Ankle arthrodesis (AA) provides reliable pain relief, good patient satisfaction scores, and improved overall function. However, this procedure has been associated with numerous complications and sequelae, such as pseudoarthrosis, malunion, gait abnormalities, increased demand on surrounding joints, and a long period of convalescence. Conversion to total ankle arthroplasty (TAA) is a potential option in the management of these complex and challenging situations.

A Comparison of Outcomes of Revision Surgical Options for the Treatment of Failed Bulk Talar Allograft Transfer: A Systematic Review.

Talar bulk osteochondral allograft transplantation is a useful treatment strategy for large, uncontained osteochondral lesions of talus. Complications and high revision rates from osteochondral talar allograft transfer can be common. Talar graft failure is a devastating complication that results from failure of allograft incorporation within the host bone and subsequent resorption and sometimes subsidence can occur.

Complications of En Bloc Osteochondral Talar Allografts and Treatment of Failures: Literature Review and Case Report.

Reoperation rates and complication rates can be high for patients receiving an osteochondral talar allograft transplant. Complications can include graft failure, delamination of the graft, arthrofibrosis, advancing osteoarthritis, nonunion of malleolar osteotomies, and partial or complete osteonecrosis of the talus. Graft failure refers to failure of graft incorporation with subsequent necrosis and subsidence.
