Arthroscopic Tarsometatarsal Arthrodesis.

Tarsometatarsal (Lisfranc) osteoarthritis can be a disabling condition and is commonly due to posttraumatic causes. Tarsometatarsal arthrodesis is indicated if the pain does not subdue with conservative treatment. Classically, this is performed as an open procedure. The purpose of this technical note is to describe a minimally invasive approach of arthroscopic arthrodesis of the involved tarsometatarsal joints. The arthroscopic procedure is performed through the junction portals of the involved articulation. It has the advantages of better cosmesis, less wound complication, less bone resection, and more thorough joint debridement. However, it is contraindicated if there is an associated significant foot deformity or shortening of the involved foot rays.
