INTRODUCTION: Knee arthrodesis is an established procedure for limb salvage after failed total knee arthroplasty (TKA) in cases of recurrent @entity9244 , reduced bone stock or with a deficient extensor mechanism. Walking with an arthrodesis is more efficient and less costly in terms of energy expenditure than above-knee amputation. Surgical options include an arthrodesis nail, external fixator or compression plate. We present our results of knee arthrodesis using the modular Wichita Fusion Nail(  ) in @entity1 after infected TKA. METHODS: Fifteen @entity1 with irretrievably failed TKA, due to @entity281 , who underwent arthrodesis with the Wichita Fusion Nail(  ) from 2004 to 2012 were retrospectively reviewed to assess fusion rate, time to fusion, complication rate, including new @entity281 , and ambulatory status. RESULTS: Three @entity1 were lost to follow-up. Mean follow-up was 33  months (6-132  months). At their most recent follow-up, all @entity1 were walking with full weight bearing on a fused arthrodesis. Mean time to union was 9  months (3-29  months). Three @entity1 necessitated a revision arthrodesis to achieve union after a mean of 5  months after the last procedure. CONCLUSION: Arthrodesis with the Wichita Fusion Nail(  ) provides satisfactory results in @entity1 with failure after infected TKA, with 75  % primary union rate and no new or persistent @entity281 at last follow-up visit. Although burdened with a high complication rate, it represents an acceptable option for limb salvage in this particular pathology.
