Ankle arthroplasty is more functional & less cosmetic troublesome than arthrodesis, and with more developed prosthesis design, more good result will come.
The authors operated 6 cases of Total Ankle arthroplasty for post traumatic and Rheumatoid Arthritis of ankle, which were also indications of arthrodesis, and introduce the results and operative problems of ankle arthroplasty.
