Metaphyseal Fixation Adam A. Sassoon, MD Arlen D. Hanssen, MD Introduction Management of severe bone loss is one of many challenges during revision total knee arthroplasty (TKA). The restoration of a metaphyseal platform that adequately supports the subsequent joint reconstruction affects implant…
Impaction Bone Grafting Leo A. Whiteside, MD Chapter Preview Chapter Synopsis Repair and reconstruction of a failed total knee arthroplasty (TKA) should begin with a plan that includes conservative treatment of the bone and soft tissues, restoration of bone stock with…
