Is deltoid and lateral ligament reconstruction necessary in varus and valgus ankle osteoarthritis, and how should these procedures be performed?

Overview

Varus and valgus ankle deformities represent a challenge to the foot and ankle surgeons. The presence of degenerative changes of the tibiotalar joint articular surfaces introduces an additional layer of complexity. Reconstruction of such deformities requires a customized approach to each patient. Surgical intervention often requires joint-sparing realignment, arthroplasty, and/or arthrodesis, depending on the severity of deformity and the joint surface integrity. The ligamentous stability of the ankle plays an essential role in the preservation and optimization of function. This article reviews the role of deltoid and lateral ligament reconstruction in the treatment of varus and valgus ankle osteoarthritis.
