Modern Techniques in Knee Arthrodesis

Abstract

Knee arthrodesis serves as an option of salvage treatment for failed total knee arthroplasty procedures. Multiple different arthrodesis techniques exist that cater to the specific presentation of the failed total knee arthroplasty, the three most common techniques being intramedullary nails, external fixation, and compression plates. This review aims to present recent findings of knee arthrodesis procedures regarding the indications, outcomes, and prognostic factors as well as a general description of the technical aspects, advantages, and disadvantages of each specific knee arthrodesis technique. Data was collected and compared between the individual techniques based on fusion rate, average time to fusion, average complication rate, types of complications, average postoperative recurrent infection rate, and average leg length discrepancy. Finally, the author’s preferred technique based on clinical experience is presented.
