Femoroacetabular impingement (FAI) is a commonly recognized condition in athletes characterized by activity-related hip pain and stiffness, which if left untreated can progress to hip osteoarthritis. The aim of the study was to determine the effect of symptomatic FAI on performance in young athletes based on the hypothesis that athletes with FAI would show deficits in performance compared with healthy controls.
The functional performance of a cohort of preoperative, competitive sportsmen with symptomatic FAI (FAI group, n = 54), was compared with that of a group of age, sex and activity-level matched controls (n = 66).
Participants performed functional tests including a 10-m sprint, a modified agility T-test, a maximal deep squat test and a single-leg drop jump (reactive strength index). Hip range of motion was assessed by measuring maximal hip flexion, abduction, and internal rotation (at 90 degree hip flexion).
The FAI group was significantly slower during the 10-m sprint (3%, P = 0.002) and agility T-test (8%, P < 0.001); flexion, abduction, and internal rotation values for the FAI group were reduced compared with controls (P < 0.001). No significant differences between groups were identified for squat depth or reactive strength index. The FAI group also reported higher levels of anterior groin pain during the 10-m sprint, modified agility T-test, and while squatting.
Many sportsmen with confirmed FAI continue sports participation up to and after diagnosis, despite issues with activity-related pain and stiffness. This study highlights the functional limitations in speed, agility, and flexibility that are likely to be present in this group of FAI patients.
股骨髋臼撞击症（FAI）是运动员中一种常见病症，其特征为与活动相关的髋关节疼痛和僵硬，若不治疗可发展为髋关节骨关节炎。本研究的目的是基于以下假设确定有症状的FAI对年轻运动员运动表现的影响，即与健康对照组相比，患有FAI的运动员在运动表现上会出现缺陷。
将一组有症状的术前竞技运动员（FAI组，n = 54）的功能表现与一组年龄、性别和活动水平相匹配的对照组（n = 66）进行比较。
参与者进行了功能测试，包括10米短跑、改良敏捷T测试、最大深度深蹲测试和单腿下落跳（反应力量指数）。通过测量最大髋关节屈曲、外展和内旋（髋关节屈曲90度时）来评估髋关节活动范围。
FAI组在10米短跑（3%，P = 0.002）和敏捷T测试（8%，P < 0.001）中明显较慢；与对照组相比，FAI组的屈曲、外展和内旋值降低（P < 0.001）。两组在深蹲深度或反应力量指数方面未发现显著差异。FAI组在10米短跑、改良敏捷T测试和深蹲时也报告了更高水平的腹股沟前疼痛。
许多确诊为FAI的运动员在诊断前后仍继续参加运动，尽管存在与活动相关的疼痛和僵硬问题。本研究强调了这组FAI患者可能存在的速度、敏捷性和灵活性方面的功能限制。
