Twenty-seven knees in 23 patients, all with seropositive rheumatoid arthritis and failed total knee arthroplasty, were treated by arthrodesis. Twenty of the 27 knees were solidly fused. A fusion aligned in 7 degrees +/- 5 degrees of valgus and knee flexion from zero to 30 degrees was associated with the highest rate of arthrodesis, the lowest rate of progression of disease in other joints, and the highest functional scores. Stable fixation using either internal or external fixation gave the most predictable rate of arthrodesis. Persistent sepsis and bone stock losses were associated with failure of arthrodesis, even under the best circumstances. All of the 20 successfully arthrodesed knees were completely functional.
23例患者的27个膝关节，均为血清学阳性类风湿性关节炎且全膝关节置换术失败，接受了关节融合术治疗。27个膝关节中有20个牢固融合。融合角度为外翻7度±5度且膝关节屈曲从零度到30度与最高的关节融合率、其他关节疾病最低的进展率以及最高的功能评分相关。使用内固定或外固定的稳定固定给出了最可预测的关节融合率。即使在最佳情况下，持续的脓毒症和骨量丢失也与关节融合失败有关。所有20个成功进行关节融合的膝关节均完全恢复功能。
