For the purpose of obtaining the most ideal and precise placement in future total knee prostheses, we evaluated the position of the devices used in such operations at our hospital by our own radiological scoring system. In a follow-up period of three years and nine months on 71 joint operations in 51 cases evaluated through radiography, 41 received scores of excellent (51%) ; 19, good (27%) ; 9, fair (12%) ; and 2, poor (3%) . The early clinical results of total knee arthroplasty were compared with these.<BR>The results showed that there were tendencies for cases with good clinical results to have good radiological scores and, to the contrary, for cases with poor results not to.<BR>In this short term study there was no significant positive correlation between good clinical results and a well-positioned prosthesis. But it seemed suggested that long-term clinical results would definitely be correlated with the positioning of the prosthesis.<BR>The comparison of the total condylar type and the kinematic type of total knee replacement showed that the kinematic type was better than the total condylar type in both clinical and radiological scores.
