Abstract

PURPOSE
To evaluate the mid-term clinical, radiographic results in P.F.C total knee replacement arthroplasty (TKRA) retrospectively.
MATERIALS AND METHODS
Between Aug. 1989 and Jun. 1995, the status of 70 knees in 45 patients was followed retrospectively for at least 5 years, the mean being 7.9 (5-10.4) years.
RESULTS
The average range of motion increased from 96 preoperatively to 118 at the lastest follow-up. In patients with rheumatoid arthritis, the average of 34 in the preoperative knee rating score and 23 in the function score improved to an average of 86 and 78, respectively. In the patient with osteoarthritis, the scores also improved from 41 and 39 to 88 and 84. Roentgenographic evaluation revealed a radiolucency rate of 36%. The total radiolucency score was 1.7. Reoperations were needed because of a deep infection that later developed in 2 cases, aseptic loosening in 2 cases and wear of polyethylene in 1 case.
CONCLUSION
The mid-term results of P.F.C TKRA were reliable and good in that there was an increased range of motion, a restoration of function, relatively rare complications (5.8%) and the patients were well satisfied. However we consider that a long-term follow-up evaluation is needed in order to monitor changes in the rate of radiolucency.
