PURPOSE
The SFAV (Simple Foot and Ankle Value) consists in asking patients how they rate their joint function on the day of the examination, as a percentage of that of a normal joint (0-100% scale with 100% being normal). The main objective was to validate the SFAV by determining its correlation with validated foot and ankle function scores.
METHODS
This was a prospective study. 90 patients were included in three groups: patients 16 to 54 years old with an acute or subacute ankle pathology (foot/ankle trauma patient group), patients more than 55 years old with ankle or foot osteoarthritis (foot/ankle degeneration patient group), and adults of any age without foot or ankle pathology (control group). A self-administered questionnaire with the American Orthopedic Foot and Ankle Society, The European Foot and Ankle Society, the Foot and Ankle Outcome Score, the Visual Analogic Scale, and the SFAV was given at three different timepoints (enrollment, preoperative visit, and 6-month postoperative visit) to the patients. The validity of the SFAV was investigated by determining its correlation with the existing foot and ankle PROMs using Spearman's correlation; test-retest reliability, the responsiveness to change, and the discriminative ability of the SFAV were also analyzed. The significance threshold was set at 0.05.
RESULTS
The SFAV was significantly correlated with the AOFAS, EFAS, and FAOS at all tested time points, with all p values below 0.033. SFAV scoring was reliable over time, as p values resulting from the comparison between initial and preoperative SFAV were all above the significance threshold. SFAV scoring was responsive to change, based on the comparison between pre- and postoperative SFAV (p < 0.05). Like for the AOFAS, EFAS, and FAOS, SFAV provides good discrimination between a healthy subject and a patient. The control group scores and initial consultation scores of the pooled patient's groups were statistically correlated (p < 0.05).
CONCLUSION
The SFAV is a valid outcome measure correlated with the AOFAS, EFAS, FAOS, and VAS.

目的
简单足踝关节评分（SFAV）在于询问患者在检查当天如何对其关节功能进行评分，以正常关节功能的百分比表示（0 - 100%范围，100%为正常）。主要目的是通过确定其与已验证的足踝关节功能评分的相关性来验证SFAV。
方法
这是一项前瞻性研究。90名患者被纳入三组：16至54岁患有急性或亚急性踝关节病变的患者（足/踝关节创伤患者组）、55岁以上患有踝关节或足部骨关节炎的患者（足/踝关节退变患者组）以及任何年龄无足踝关节病变的成年人（对照组）。在三个不同时间点（入组时、术前访视和术后6个月访视）向患者发放一份包含美国矫形足踝协会、欧洲足踝协会、足踝结果评分、视觉模拟量表和SFAV的自填式问卷。通过使用Spearman相关性确定SFAV与现有的足踝关节患者报告结局量表（PROMs）的相关性来研究SFAV的有效性；还分析了SFAV的重测信度、对变化的反应性和鉴别能力。显著性阈值设定为0.05。
结果
在所有测试时间点，SFAV与美国矫形足踝协会（AOFAS）、欧洲足踝协会（EFAS）和足踝结果评分（FAOS）均显著相关，所有p值均低于0.033。随着时间推移，SFAV评分具有可靠性，因为初始和术前SFAV比较得出的p值均高于显著性阈值。基于术前和术后SFAV的比较，SFAV评分对变化有反应（p < 0.05）。与AOFAS、EFAS和FAOS一样，SFAV在健康受试者和患者之间具有良好的鉴别能力。合并患者组的对照组评分与初始咨询评分具有统计学相关性（p < 0.05）。
结论
SFAV是一种有效的结局指标，与AOFAS、EFAS、FAOS和视觉模拟量表（VAS）相关。
证据水平
