The talonavicular joint is a common site for osteoarthritis of the foot. Talonavicular arthrodesis is the surgical treatment for symptomatic talonavicular osteoarthritis. Classically, this is performed via an open approach and is associated with a rate of nonunion that ranges from 3% to 37%. Arthroscopic talonavicular arthrodesis has been proposed to provide better intra-articular visualization, conserve bone blood supply to improve the union rate, and reduce soft-tissue complications such as wound dehiscence, infection, and neurovascular injury. The purpose of this Technical Note is to describe the details of arthroscopic talonavicular arthrodesis for management of talonavicular osteoarthritis.
