Liner Exchange and Bone Grafting: Rare Option to Treat Wear Lysis of Stable TKAs

摘要

BackgroundLiner exchange and bone grafting are commonly performed for wear and osteolysis around well-fixed modular acetabular components that otherwise would require structural allografting and revision THA. However, liner exchange in the face of substantial lysis around TKA has been performed rarely with reports of failure rates of up to 25% at 3 year followup.
