Identifying optimal treatment strategies in patients with traumatic foot and ankle injuries has been hampered by the use of multiple available outcome measures with unproven reliability and validity. This prospective observational study aimed to measure the correlation between six functional outcome measures in patients with traumatic foot and ankle injuries.
Patients 18 years of age or older with a traumatic foot or ankle injury completed the Short Form-12 (SF-12), Short Musculoskeletal Functional Assessment (SMFA), Foot Function Index (FFI), Foot and Ankle Ability Measure (FAAM), American Academy of Orthopedic Surgeons (AAOS), Foot and Ankle Questionnaire and American Orthopedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scale at a single followup visit. Raw scores for each of the outcome measures were calculated. Fifty-two patients were enrolled in our study. Pearson correlation coefficients provided measures of correlation.
Moderate to strong correlations were found for most pairwise comparisons of raw scores and functional categorical rankings (ρ=|0.5243 to 0.92|, p < 0.002). The strongest correlations were found between the SMFA, FFI, FAAM and AAOS Foot and Ankle Questionnaire.
High correlations between scores on six commonly used functional outcome instruments suggest it is likely unnecessary to use more than one instrument when examining functional outcome in patients with traumatic foot and ankle injuries. However, inconsistencies between measures in the same patient population suggest a need for further validation and scrutiny.
由于多种可用的结果测量方法的可靠性和有效性未经证实，因此在创伤性足踝损伤患者中确定最佳治疗策略受到了阻碍。本前瞻性观察研究旨在测量创伤性足踝损伤患者的六种功能结果测量方法之间的相关性。
18 岁或以上的创伤性足踝损伤患者在单次随访就诊时完成了 12 项简短健康调查（SF-12）、短肌肉骨骼功能评估（SMFA）、足部功能指数（FFI）、足踝能力测量（FAAM）、美国矫形外科医师学会（AAOS）、足踝问卷和美国矫形足踝协会（AOFAS）踝关节-后足量表。计算了每种结果测量的原始分数。我们的研究共纳入了 52 名患者。皮尔逊相关系数提供了相关度的度量。
大多数原始分数和功能分类评分的两两比较都发现了中度到高度相关性（ρ=|0.5243 至 0.92|，p<0.002）。SMFA、FFI、FAAM 和 AAOS 足踝问卷之间的相关性最强。
六种常用功能结果工具的评分之间高度相关，这表明在检查创伤性足踝损伤患者的功能结果时，可能不需要使用超过一种工具。然而，同一患者群体中测量方法的不一致表明需要进一步验证和审查。
