Managing substantial bone loss is a challenge in revision total knee arthroplasty. The etiology of bone loss is usually multifactorial and can range from subsidence of loose implants, stress shielding, and periprosthetic osteolysis to osteonecrosis and even infection1. Goals of revision total knee arthroplasty include preservation of host bone, correction of sagittal and coronal alignment, restoration of flexion-extension balance, optimization of ligamentous stability, and establishment of a stable bone-implant interface. Selection of reconstructive methods such as bone cement and screws, block augments, impaction or bulk allografts, or metaphyseal sleeves and cones is determined by the location and quantity of osseous defects in the femur and tibia. This article reviews the different operative methods for dealing with bone loss in revision total knee arthroplasty.
