Patients and methods
Between January 1992 and December 1995, 126 consecutive primary cemented TKAs were carried out in 108 patients, using the Press-Fit Condylar (PFC) TKA system (Johnson & Johnson Professional Inc, Raynham, MA) [6]. The average age at the time of operation was 67.4 years (SD, 11.3 years). There were 67 patients (77 knees) with osteoarthritis, 37 patients (44 knees) with rheumatoid arthritis, 3 patients (4 knees) with juvenile rheumatoid arthritis, and 1 patient (1 knee) with hemophilic
Knee society clinical rating system
The average preoperative knee score for all 128 knees was 32.9 (SD, 16.3), whereas the average preoperative Function Score for all 128 knees was 29.1 (SD, 18.0). The average follow-up knee score for the 100 knees was 83.5 (SD, 12.9), for knees with rheumatoid arthritis, 86.9 (SD, 8.3); and for knees with osteoarthritis, 81.7 (SD, 14.5). The average follow-up function score for the 100 knees was 51.5 (SD, 28.), for knees with rheumatoid arthritis, 51.6 (SD, 29.3); and for knees with
Discussion
Total condylar TKAs yield excellent clinical and radiologic results 1, 2, 3. Results differ, however, depending on the evaluation assessment. The Knee Society knee score may not be a sensitive tool for the assessment of outcome after TKA because most TKAs score >80 points at any follow-up stage 1, 2, 3, 17. Radiologic assessment seemed to be nonspecific in predicting results because no significant correlation between the occurrence of thin radiolucent lines and clinical results has been
