Abstract:
When a periprosthetic fracture about the knee or hip is associated with segmental bone loss and a loose implant, a structural allograft may be indicated. The implant is cemented into the allograft but not into the host. The host graft junction is stabilized by the long stem of the implant and a step-cut osteotomy. The junction can be further reinforced by cortical strut allograft and residual host bone with soft tissues still attached to enhance union. Once the host bone unites to the allograft, the reconstruction is stabilized.
