Tibial Bushing Wear at 28 Years of Follow-up After Rotating-Hinge Distal Femoral Replacement

Abstract

Case: A 58-year-old woman presented with swelling, stiffness, and pain of the right knee 28 years after rotating-hinge distal femoral replacement after osteosarcoma resection. She underwent revision. There was wear through the entire thickness of the polyethylene tibial sleeve bushing, and the implant was well-fixed. The knee was reassembled with new bushings, sleeves, yoke, axle, poly, and a locking pin. Conclusion: This is the first described case of tibial sleeve bushing wear. It highlights the importance of early detection of potential complications and implant surveillance because it can enable surgeons to intervene with minor procedures, avoiding eventual catastrophic failure.
