In a consecutive series of patients with advanced, seropositive rheumatoid arthritis, 112 severely damaged knees were reconstructed with a stabilizing, total resurfacing prosthesis in 80%, a hemiprosthesis in 13% (3% biocompartmental) and a hinge prosthesis in 7%. Eighty per cent of patients receiving the resurfacing prosthesis were satisfied and, in addition, 8% improved at prospective follow-up examinations one to 5 years postoperatively. The subjective results showed good correspondance with the clinical and roentgenologic assessments. The joints reconstructed with the total resurfacing prosthesis were free from effusion or any inflammatory activity in 96%, stable in 88%, and showed full correction of deformity in 84% while 16% showed a fixed flexion of 10 degrees up to 20 degrees. Walking ability with regard to the need for walking aids was considerably improved. So far, 2% of the knees have had the prosthesis removed and a fusion performed; one per cent because of primary deep infection and the other one per cent because of late deep infection. Four per cent of the cases have shown loosening of the tibial component, necessitating reoperation.
在一系列连续性晚期血清阳性类风湿关节炎患者中，112个严重受损膝关节进行了重建，其中80%采用稳定型全表面置换假体，13%采用半关节置换假体（3%为双髁置换），7%采用铰链式假体。接受表面置换假体的患者中，80%感到满意，此外，8%在术后1至5年的前瞻性随访检查中有改善。主观结果与临床和放射学评估结果吻合良好。采用全表面置换假体重建的关节，96%无积液或任何炎症活动，88%稳定，84%畸形完全矫正，16%有10度至20度的固定屈曲。在行走辅助器具需求方面，行走能力有显著改善。到目前为止，2%的膝关节已进行了假体取出并施行融合术；1%是由于原发性深部感染，另1%是由于晚期深部感染。4%的病例出现胫骨部件松动，需要再次手术。
