We report the survival of AGC knee endoprosthesis from the Finnish Arthroplasty Register for 2 indications, osteoarthrosis (OA, 6,306 knees) and rheumatoid arthritis (RA, 2,161 knees) during 1985-1999. Survivorship analysis was performed with revision as an endpoint. We found similar survival rates. In the OA group, survival after 5 years was 97% and it was 94% after 10 years. In the RA group the corresponding figures were 97% and 96%, respectively. There was no significant difference in survival whether or not cement was used for fixation. The revision rates were higher in men and in younger patients.
