Reconstruction of the lateral tibial condyle by a pedicled vascularized fibular graft after en bloc resection of giant cell tumour.

Two patients with giant cell tumour of the lateral tibial condyle underwent en bloc resection and reconstruction by pedicled vascularized fibular graft. Both had good functional results and rapid solid bony union. This procedure preserved the lateral stabilizing structures of the knee, allowed relatively early mobilization and provided some cartilagionous surface for articulation with the lateral femoral condyle. The procedure was technically simple compared with homograft reconstruction, prosthetic replacement or free vascularized bone grafts, and could be performed in less sophisticated centres. The operation also provided additional bone stock for subsequent fusion if necessary.
