Objective: To analyze the experience with allograft transplantation of the extensor mechanism in total knee arthroplasty and compare results with the international experience.
Methods: We retrospectively evaluated three cases of extensor mechanism allograft after total knee arthroplasty performed in our hospital with the aid of one of the few tissue banks in Brazil and attempt to establish whether our experiences were similar to others reported in the world literature regarding patient indication, techniques, and outcomes.
Results: Two cases went well with the adopted procedure, and one case showed bad results and progressed to amputation.
