BACKGROUND
End-stage ankle arthritis should have an appropriate classification to assist surgeons in the management of end-stage ankle arthritis. Outcomes research also requires a classification system to stratify patients appropriately.
MATERIALS AND METHODS
Six fellowship trained foot and ankle surgeons met on two occasions to derive a classification system for end-stage ankle arthritis. A four-part classification system was designed. Four surgeons reviewed blinded patient profiles and radiographs on two occasions to determine the inter- and intraobserver reliability.
RESULTS
Good interobserver reliability (kappa = 0.62) and intraobserver reproducibility (kappa = 0.72) was demonstrated for the classification system.
CONCLUSION
The COFAS classification system appears to be a valid tool for the management and research of end-stage ankle arthritis.
背景
终末期踝关节关节炎应有合适的分类，以帮助外科医生对终末期踝关节关节炎进行管理。结果研究也需要一个分类系统来适当分层患者。
材料与方法
六位足部和踝关节专科住院医生在两次会议上讨论出了一种终末期踝关节关节炎的分类系统。设计了一个四部分的分类系统。四位外科医生两次对盲选的患者资料和 X 光片进行了评估，以确定分类系统的组内和组间可靠性。
结果
该分类系统显示出良好的组间可靠性（kappa = 0.62）和组内可重复性（kappa = 0.72）。
结论
COFAS 分类系统似乎是管理和研究终末期踝关节关节炎的有效工具。
