AI Article Synopsis
- Bone deficiency can cause issues with aligning and stabilizing implants in revision total knee arthroplasty (TKA).
- Different treatments for these bone defects vary based on their size and location, including options like cement, metal augments, and allografts.
- Recent advancements have introduced porous tantalum as a promising material for managing these defects, and a review of the advantages and disadvantages of each method was conducted.
Article Abstract
Bone deficiency hinders implant alignment and stabilisation of the bone-implant interface in revision total knee arthroplasty (TKA). Treatments for bone defects include bone cement, bone cement with screw reinforcement, metal augments, impaction bone grafts, structural allografts, and tantalum, depending on the location and size of the defects. Small defects are usually treated with cement, cement plus screws, or impaction allograft bone. Large defects are repaired with structural allografts or metal augments. Recent developments involve the use of highly porous osteoconductive tantalum. We reviewed the pros and cons of each method for bone defect management in revision TKA.
