Abstract

Background: The purpose of this study was to validate the Foot and Ankle Outcome Score (FAOS) for osteochondral lesions of the talus (OLTs). We hypothesize that the FAOS will meet all 4 psychometric criteria for validity in this patient population.

Methods: From 2008 to 2014, a total of 208 patients with OLTs were included in the construct validity portion of the study. All patients completed FAOS and 12-Item Short-Form Health Survey (SF-12) scores. Twenty additional patients were prospectively recruited and were asked to complete questionnaires to determine the relevance of each of the FAOS questions as it related to their OLT. Forty-four patients completed the FAOS 1 month after the first FAOS to assess reliability via Spearman correlation coefficient. Responsiveness of the FAOS was assessed with 54 patients who had both preoperative and postoperative FAOS scores via Student paired t test with significance determined as P < .05. In total, 229 unique patients were included in this study.

Results: Statistically significant associations were found between all FAOS and SF-12 subscales (P < .01). The FAOS symptoms subscale demonstrated the lowest correlation with the SF-12 physical health domains. No floor or ceiling effects were identified. Weak correlations were calculated between the 5 FAOS subscales and the SF-12 mental component summary score. All FAOS domains met the threshold for acceptable content validity (score > 2.0). All FAOS subscales demonstrated acceptable test-retest reliability, with ICC values ranging from 0.81 (ADL) to 0.92 (Pain).

Conclusion: This study demonstrates the acceptable yet moderate construct and content validity, reliability, and responsiveness of the FAOS for patients with OLTs of the ankle joint. We endorse the use of the FAOS in evaluating ankle OLTs in both the research and clinical setting and consider it a useful patient-reported, self-administered instrument following surgical intervention.

Level of evidence: Level IV, retrospective case study.

踝关节骨软骨损伤足踝关节结果评分(FAOS)的验证。
背景:本研究的目的是验证距骨骨软骨损伤(OLTs)的足部和踝关节结果评分(FAOS)。我们假设FAOS将满足该患者群体中所有4个有效性心理测量标准。方法:从2008年到2014年,共有208名OLT患者被纳入研究的结构有效性部分。所有患者均完成了FAOS和12项简式健康调查(SF-12)评分。另外20名患者被前瞻性招募,并被要求完成问卷调查,以确定每个FAOS问题与OLT的相关性。44名患者完成了FAOS 1 第一次FAOS后一个月,通过Spearman相关系数评估可靠性。通过Student配对t检验对54名术前和术后FAOS评分的患者进行了FAOS反应性评估,其显著性确定为P 结果:所有FAOS和SF-12分量表之间存在统计学上显著的相关性(P  2.0)。所有FAOS分量表均显示出可接受的重测可靠性,ICC值范围从0.81(ADL)到0.92(疼痛)。结论:本研究证明了FAOS对踝关节OLT患者的结构和内容的可接受但适度的有效性、可靠性和反应性。我们赞同在研究和临床环境中使用FAOS来评估踝关节OLT,并认为它是一种有用的患者报告的手术干预后自我管理的仪器。证据级别:四级,回顾性案例研究。

期刊介绍: Foot & Ankle International (FAI), in publication since 1980, is the official journal of the American Orthopaedic Foot & Ankle Society (AOFAS). This monthly medical journal emphasizes surgical and medical management as it relates to the foot and ankle with a specific focus on reconstructive, trauma, and sports-related conditions utilizing the latest technological advances. FAI offers original, clinically oriented, peer-reviewed research articles presenting new approaches to foot and ankle pathology and treatment, current case reviews, and technique tips addressing the management of complex problems. This journal is an ideal resource for highly-trained orthopaedic foot and ankle specialists and allied health care providers. The journal’s Founding Editor, Melvin H. Jahss, MD (deceased), served from 1980-1988. He was followed by Kenneth A. Johnson, MD (deceased) from 1988-1993; Lowell D. Lutter, MD (deceased) from 1993-2004; and E. Greer Richardson, MD from 2005-2007. David B. Thordarson, MD, assumed the role of Editor-in-Chief in 2008. The journal focuses on the following areas of interest: • Surgery • Wound care • Bone healing • Pain management • In-office orthotic systems • Diabetes • Sports medicine
