Knee Arthrodesis Using the Wichita Fixation Rod

Abstract

For patients with a failed total knee replacement that is unsalvageable, only few treatment options remain. Knee arthrodesis is a valuable alternative to amputation in these cases. Several fusion techniques have been described, including external fixation, plate and screw osteosynthesis, and intramedullary rods. The Wichita fusion nail is an intramedullary rod that allows compression at the arthrodesis site. Furthermore, only 1 surgical exposure is required, and early weight bearing is allowed. This article describes in detail the technique used for implantation of the Wichita fusion nail and discusses the indications, results, and complications.
