Morselized bone grafting of defects in revision total knee arthroplasty

In a prospective, multicenter study evaluating one revision knee system, 33 of 409 patients underwent morselized bone grafting for tibial and femoral defects. Fifty-four percent of defects were bicondylar and the defect volum es averaged 36 cc(3). There was no difference in preoperative or postoperat ive knee scores between patients undergoing morselized grafting and the ent ire group. Radiographic evaluation showed remodeling of the grafted areas c onsistent with viable incorporation of the graft. The incidence of radioluc ent lines, at 2 years followup, was not different between the patients who received grafting and the patients who did not receive grafting. There have been no clinical failures or reoperations in the patients who received mor selized bone grafting. Morselized bone grafting seems to offer a viable alt ernative in the reconstruction of osseous defects in patients undergoing re vision total knee arthroplasty.
