Total knee replacement in an amputee patient: a case report.

Osteoarthritis is the most prevalent and more disabling of the rheumatic diseases. One of the most effective forms of treatment of severe osteoarthritis is total joint arthroplasty. Although studies suggest that the incidence of osteoarthritis is higher in prosthetic users, research supporting total joint arthroplasty as an option for treating amputee patients with advanced osteoarthritis is lacking. We report the case of a 76-year-old man with right transtibial amputation who had an excellent outcome after undergoing bilateral total knee replacements for advanced osteoarthritis.
