The deficiency of bones is a major problem it hinders alignment of implant and prevents stabilization of the bone-implant interface in revision total knee arthroplasty (TKA). Treatments to the bone defects are numerous, they include such treatments as: bone cement, bone cement with a screw, structural allografts, tantalum and metal augments. Different techniques are used depending on placement and size of defect. Big defects usually repaired using structural allografts and metal augments. Small defects are most commonly treated with bone cement, bone cement with a screw, structural allografts. The latest addition to the treatment methods were highly porous osteoconductive tantalum wich are used in cases of major bone defects. In this paper were reviewed pros and cons of each method for bone defect management in revision TKA.
