To explore associations between hip muscle strength and cartilage defects (presence and severity) on magnetic resonance imaging (MRI) in young adults with hip/groin pain participating in sub-elite football. Sub-elite football players with hip/groin pain (>6 months) completed assessments of isometric hip strength and functional task performance. Hip cartilage defects were assessed using the Scoring Hip Osteoarthritis with MRI tool. This exploratory, cross-sectional study used logistic and negative binomial models to assess the relationships between hip muscle strength or functional task performance and hip cartilage defects, controlling for body mass index, age, testing site and cam morphology, incorporating sex-specific interaction terms. One hundred and eighty-two (37 women) sub-elite (soccer or Australian football) players with hip/groin pain (age 26 ± 7 years) were included. Greater hip extension strength was associated with higher cartilage total score (adjusted incidence rate ratio [aIRR] 1.01, 95%CI: 1.0 to 1.02, p = 0.013) and superolateral cartilage score (adjusted odds ratio (aOR) 1.03, 95% confidence interval (CI): 1.01 to 1.06, p < 0.01). In female sub-elite football players, greater hip external rotation strength was associated with lateral cartilage defects (aOR 1.61, 95%CI: 1.05 to 2.48, p = 0.03) and higher cartilage total score (aIRR 1.25, 95%CI: 1.01 to 1.66, p = 0.042). A one-repetition increase in one-leg rise performance was related to lower odds of superomedial cartilage defects (aOR 0.96, 95%CI: 0.94 to 0.99, p < 0.01). Overall, there were few associations between peak isometric hip muscle strength and overall hip cartilage defects. It is possible that other factors may have relevance in sub-elite football players. Additional studies are needed to support or refute our findings that higher one leg rise performance was associated with reduced superomedial cartilage defect severity and greater hip extension strength was related to higher cartilage defect severity scores.

髋部/腹股沟疼痛的亚精英足球运动员的髋部肌肉力量/功能与髋部软骨缺陷之间的关联


旨在探讨参加亚精英足球比赛的髋部/腹股沟疼痛的年轻人的磁共振成像 (MRI) 髋部肌肉力量与软骨缺陷（存在和严重程度）之间的关联。患有髋部/腹股沟疼痛（>6 个月）的亚精英足球运动员完成了等长髋部力量和功能性任务表现的评估。使用 MRI 工具评分髋关节骨关节炎来评估髋关节软骨缺陷。这项探索性横断面研究使用逻辑和负二项式模型来评估髋部肌肉力量或功能性任务表现与髋部软骨缺陷之间的关系，控制体重指数、年龄、测试部位和凸轮形态，并纳入性别特异性相互作用项。包括 182 名（37 名女性）患有髋部/腹股沟疼痛（年龄 26 ± 7 岁）的亚精英（足球或澳式足球）运动员。髋部伸展强度越大，软骨总评分越高（调整后发生率比 [aIRR] 1.01，95%CI：1.0 至 1.02，p = 0.013）和上外侧软骨评分（调整后比值比 (aOR) 1.03，95% 置信区间） (CI)：1.01 至 1.06，p < 0.01）。在女亚精英足球运动员中，较大的髋部外旋力量与外侧软骨缺损（aOR 1.61，95%CI：1.05至2.48，p = 0.03）和较高的软骨总分（aIRR 1.25，95%CI：1.01至1.66，p = 0.042）。单腿站立性能的单次重复增加与内侧软骨缺损的发生率降低有关（aOR 0.96，95%CI：0.94 至 0.99，p < 0.01）。总体而言，峰值等长髋部肌肉力量与整体髋部软骨缺陷之间几乎没有关联。其他因素可能与次精英足球运动员有关。 需要更多的研究来支持或反驳我们的发现，即较高的单腿抬高表现与内侧软骨缺损严重程度降低相关，而髋部伸展强度越大与软骨缺损严重程度得分越高相关。
