Reconstruction of large bone defects of the femur remains a difficult problem during revision TKA. Smaller defects have generally been treated with morselized cancellous bone graft; filling of the defect with cement; use of reinforcing screws in cement; or commercially available modular block augments, which are offered as options for use in nearly all contemporary revision knee systems. However, larger bone defects may require more extensive reconstruction techniques in order to restore mechanical stability to the femoral component against axial and rotational loading. Traditionally, these problems have been addressed with impaction bone-grafting (when mainly contained defects are present), large structural allografts, segmental replacement hinged components, metaphyseal sleeves, or custom-fabricated prosthetic components. However, despite the variety of options available, reliable reconstruction with durable long-term fixation can be difficult to achieve, with the optimal choice of techniques remaining unclear. |
