Salvage reconstruction for lateral ankle instability using a tendon allograft.
Lateral ligamentous instability may result after an inversion injury to the ankle. Although it generally responds well to nonsurgical treatment, recurrent cases may warrant surgical intervention. There is extensive literature detailing various procedures designed to restore lateral ankle stability. We describe a case in which a patient had a distal fibulectomy for multiple symptomatic osteochondromas, with reconstruction of the lateral ligament complex using peroneus brevis tendon. The patient subsequently disrupted this surgical construct with a severe inversion injury and had recurrent lateral ankle instability. The lateral ligament complex then was reconstructed using a tibiotalar bone-tendon allograft directed to counteract inversion forces. Fourteen years after the procedure, the patient remains satisfied with a painless, stable ankle. The described technique provides a salvage reconstruction of the lateral ligament complex using allograft tissue, in the unique setting of an absent fibula and deficient peroneus brevis tendon.
