Careful attention to axial alignment, soft tissue balance, and stability will minimize prosthetic failure. In revision arthroplasty a prosthesis designed to replace bone loss with the least constraint possible should be used. In the current series revision of the noninfected failed total knee arthroplasty has provided satisfactory results in 50% to 60% of the patients. We believe that use of the newer implants and instrumentation will improve results markedly.
