本研究的目的是评估导致踝关节炎的病因的分布率，并量化和比较这些病因组之间的重要临床和放射学变量。我们通过病史、体格检查和X线检查评估了390例（406个踝关节）因疼痛的终末期踝关节骨关节炎（OA）来我中心就诊的患者的数据。创伤后踝关节OA见于78%的病例（n = 318），继发性关节炎见于13%（n = 52），原发性OA见于9%（n = 36）。美国矫形足踝协会（AOFAS）后足评分平均为38分（范围，0-74分），活动度为22 A度（范围，0 A度-65 A度），疼痛视觉模拟评分为6.8（范围，2-10）。创伤后终末期踝关节OA患者比原发性OA患者更年轻。平均胫距对线为88 A度（范围：51 A度-116 A度），并且在病因组之间没有差异。我们的研究表明创伤是踝关节OA的主要原因，而原发性OA是罕见的。在大多数踝关节OA患者中，无论潜在病因如何，平均胫距对线均为内翻。证据等级：IV级，预后研究。有关证据等级的完整描述，请参见作者指南。
The purpose of this study was to evaluate the distribution rate of etiologies leading to ankle arthritis and to quantify and compare the important clinical and radiologic variables among these etiologic groups. We evaluated data from 390 patients (406 ankles) who consulted our center because of painful end-stage ankle osteoarthritis (OA) by using medical history, physical examination, and radiography. Posttraumatic ankle OA was seen in 78% of the cases (n = 318), secondary arthritis in 13% (n = 52), and primary OA in 9% (n = 36). The average American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score was 38 points (range, 0-74 points), range of motion was 22A degrees (range, 0A degrees-65A degrees), and visual analog scale for pain was 6.8 (range, 2-10). Patients with posttraumatic end-stage ankle OA were younger than patients with primary OA. The average tibiotalar alignment was 88A degrees (range, 51A degrees-116A degrees) and did not differ between the etiologic groups. Our study showed trauma is the main cause of ankle OA and primary OA is rare. In the majority of patients with ankle OA the average tibiotalar alignment is varus regardless of the underlying etiology.Level of Evidence: Level IV, prognostic study.
