Abstract
Total ankle replacement is an increasingly recommended treatment for patients with end-stage ankle osteoarthritis. The increasing experience with this procedure explains its acceptance as a therapeutic option in complex cases as part of reconstruction surgery. However, the complication rate including failure of the prosthesis should not be underestimated. Previous studies have shown that most patients developed ankle osteoarthritis secondary to previous trauma. Patients with posttraumatic osteoarthritis often have varus or valgus misalignment of the hindfoot. In cases with incorrectly addressed hindfoot misalignment and/or incorrectly positioned prosthesis components, pain may remain postoperatively because of biomechanical dysbalance and asymmetrical load. The pain is mostly localized on the medial side the so-called medial pain syndrome.The following classification of the medial pain syndrome has been established in our practice: type I medial impingement/contracture of medial ligaments, type II valgus deformity, type III varus deformity, type IV combined varus-valgus deformity.
