A follow-up study of an uncemented knee replacement. The results of 312 knees using the Kodama-Yamamoto prosthesis.
The Kodama-Yamamoto knee is an uncemented surface replacement which has been used since 1970. The design has been improved twice and this present report concerns the results of the Mark II model. Between 1980 and 1984, 350 knees were replaced in 225 patients. In 1987, a survey of 335 of these knees was conducted at two to seven years after operation. The results were excellent or good in 83% of patients. Many of the failures were because of general disorders unrelated to the operation, but in 5.4% of the knees there were local complications which continue to present problems.
