Total ankle arthroplasty and tibialis posterior tendon transfer for ankle osteoarthritis and drop foot deformity

Total ankle arthroplasty is an alternative to arthrodesis in selected patients with end-stage arthritis of the ankle. We report on the clinical features, radiographic findings, management and results in a 58-year-old man with associated ankle osteoarthritis and drop foot deformity. The patient was managed with a total ankle arthroplasty and tibialis posterior tendon transfer. Three years after the procedure, the patient was able to walk, had no pain, and had a stable joint with 5° dorsiflexion and 20° plantar flexion.
