説明

Arthroplasties were done on 13 knees in 12 patients of unicompartmental osteoarthritis using a PCA unicompartmental knee, and the patients were followed for at least two years. The clinical findings showed satisfactory results according to the criteria of the Japanese Orthopaedic Association (JOA) . The JOA score was a mean of 51.9 before surgery and 83.5 at follow-up. The mean postoperative flexion was 118°. The position of the tibial component was respectively 85.6±3.0° and 88.2±2.0° in the AP and lateral views. The mean of the postoperative femoro-tibial angle (FTA) when standing was 177°. There was no correlation between clinical results and these radiographic parameters except in one case, who had a pain in the operated on knee during walking. Her FTA was 183°, and radiography showed there to be a few loose beads. Totally, loose beads were found in 9 uncemented femoral or tibial components. These results suggest that uncemented components might be unstable for some postoperative periods. Therefore, we prefer to use cement in the PCA unicompartmental arthroplasty.
