Abstract

BACKGROUND

Iliotibial band friction syndrome (ITBFS) is an overuse injury with pain at the level of the knee lateral epicondyle. We sought to determine whether there is greater knee lateral epicondyle prominence among patients with ITBFS versus matched controls.

METHODS

Seventy five patients with ITBFS and 75 age-, height-, and sex-matched controls (n = 150 total patients) with knee magnetic resonance imaging from 2015 to 2017 were included. All cases had a diagnosis of ITBFS and a lack of other identified lateral knee injuries on magnetic resonance imaging. Controls had medial knee pain with medial meniscus tear on MRI and no clinical evidence of ITBFS. Lateral knee epicondyle height in millimeters was measured.

RESULTS

Mean patient age was 39.1 years (SD 15.1), 57% were female, and mean height was 170.0 cm (SD 9.3) with no difference between cases and controls. Mean lateral epicondyle height for cases was 13.1 mm (SD 1.6) and for controls was 12.2 (SD 1.4) with a mean difference of 0.9 mm (95% CI 0.4-1.3 mm) between matched pairs (p < 0.001). Mean epicondyle height:condylar AP width ratio was 0.211 (SD 0.023) for cases and 0.198 (SD 0.020) for controls with a mean difference of 0.013 (95% CI 0.006-0.020) between matched pairs (p < 0.001).

CONCLUSIONS

There is a significant association between greater lateral epicondyle prominence and IT band friction syndrome, suggesting another anatomic risk factor for this multifactorial condition.

摘要

背景

髂胫束摩擦综合征（ITBFS）是一种过度使用导致的损伤，在膝关节外侧髁水平处产生疼痛。我们试图确定与匹配的对照组相比，ITBFS患者的膝关节外侧髁是否更突出。

方法

纳入了75例ITBFS患者以及75例年龄、身高和性别匹配的对照者（共150例患者），这些患者均在2015年至2017年期间接受了膝关节磁共振成像检查。所有病例均诊断为ITBFS，且磁共振成像未发现其他明确的膝关节外侧损伤。对照组患者膝关节内侧疼痛，磁共振成像显示内侧半月板撕裂，且无ITBFS的临床证据。测量膝关节外侧髁高度（单位为毫米）。

结果

患者平均年龄为39.1岁（标准差15.1），57%为女性，平均身高为170.0厘米（标准差9.3），病例组和对照组之间无差异。病例组的平均外侧髁高度为13.1毫米（标准差1.6），对照组为12.2毫米（标准差1.4），匹配对之间的平均差异为0.9毫米（95%置信区间0.4 - 1.3毫米）（p < 0.001）。病例组的平均髁高度与髁前后径宽度之比为0.211（标准差0.023），对照组为0.198（标准差0.020），匹配对之间的平均差异为0.013（95%置信区间0.006 - 0.020）（p < 0.001）。
