Abstract
Ankle osteoarthritis (OA) is a degenerative condition that impacts quality of life. Total ankle replacement (TAR) represents a significant advancement in orthopedic surgery. Objectives: The purpose was to provide an overview of the indications, outcomes, and complications of anterior and lateral surgical approaches in TAR, as well as return to sport following surgery. Methods: The PubMed, MEDLINE, Scopus, and Cochrane Central databases were searched. The keywords used were “total ankle arthroplasty”, “total ankle replacement”, “ankle anterior approach”, “ankle lateral approach”, “outcomes”, “return to sport”, and “complications”, and the search included articles published from 2014 to 2024. Results: Successful functional outcomes, return to athletic activity, and return to the previous level of sports performance after surgery have been reported at rates of over 60%. The anterior approach restores the normal tibial slope but presents a high risk of wound-healing complications and medial malleolar fractures. The lateral approach allows an anatomic placement of the implant, but it is associated with fibular complications and a high risk of revision surgery. Return to sport is feasible in low-impact sports such as cycling, swimming, and dancing. Conclusions: The anterior and lateral approaches for TAR yielded satisfactory functional outcomes and rates of return to athletic activity. Different intra- and post-operative complications and revision surgery should be managed properly to optimize outcomes.
