After failure of total knee arthroplasty, arthrodesis was attempted in 120 cases, and unsuccessful in 25 (21%). Failure of arthrodesis was defined as nonunion persisting one year after arthrodesis or reoperation to obtain union. The number of attempts at arthrodesis ranged from one to four. The most frequent reasons for reoperation were persistent pain and instability. Most failures were caused by poor apposition owing to bone loss. Union was obtained in ten knees (average follow-up period, 44.5 months), but not in 11 (average, 35.3 months).
全膝关节置换失败后，对120例患者尝试进行关节融合术，其中25例（21%）未成功。关节融合失败定义为关节融合术后持续不愈合1年或再次手术以实现愈合。关节融合术的尝试次数为1至4次。再次手术最常见的原因是持续疼痛和不稳定。大多数失败是由于骨质流失导致对位不良所致。10例膝关节实现了愈合（平均随访期44.5个月），但11例未愈合（平均35.3个月）。
