New technique of arthroscopic triple arthrodesis.

Triple arthrodesis is a common procedure in foot and ankle surgery. It has a significant role in treating hind foot osteoarthrosis and deformity. We describe a new arthroscopic approach of triple arthrodesis. Through carefully planned portal placement of midtarsal joint arthroscopy, together with subtalar arthroscopy, we can denude articular cartilage of the 3 joints with minimal resection of subchondral bone. The 3 joints are put into the desired position and fixed with cannulated screws. This has the potential advantage of minimal bone removal and better fusion surface preparation, especially of the talonavicular joint.
