Joint preserving procedures for Takakura stage IIIB varus ankle osteoarthritis.

ABSTRACT

A man in his early 70s with right Takakura stage IIIB varus ankle osteoarthritis underwent medial opening wedge supramalleolar osteotomy with inframalleolar correction as joint preserving procedure. We also performed anteroinferior tibiofibular ligament (AITFL) resection with fibular shortening valgisation osteotomy to enhance the talar tilt correction. Postoperative decrease in talar tilt with dramatic symptom improvement was achieved. Performing the AITFL resection with fibular shortening valgisation osteotomy plus concomitant supramalleolar osteotomy and inframalleolar correction for Takakura stage IIIB varus ankle osteoarthritis resulted in successful improvement in talar tilt by making room for the valgus deviation of the talus.
