Kinesiophobia is a fear of physical movement and activity and is known to affect return to sports and second injury after anterior cruciate ligament reconstruction.
To determine the association among landing biomechanics, knee pain, and kinesiophobia in athletes following anterior cruciate ligament reconstruction.
A cross-sectional study.
Clinical center of sports medicine.
This study included 31 athletes who participated in sports after primary, unilateral anterior cruciate ligament reconstruction (age, median [interquartile range]: 20.0 [7.0] years; body mass index: 22.2 [2.6] kg/m ; time from anterior cruciate ligament reconstruction: 24.0 [23.0] months).
Not applicable.
Kinesiophobia was measured using the Tampa Scale for Kinesiophobia-11. Knee function included joint laxity, strength, and single-leg hop distance. Knee pain intensity during sports activities was measured using a numerical rating scale. Vertical ground reaction force was measured, and electromyography data for the vastus medialis and semitendinosus muscles during single-leg jump landing were collected. Univariate correlation analysis and multiple regression analysis were performed to identify the associations between the Tampa Scale for Kinesiophobia-11 score and outcome measures.
There was no correlation between peak vertical ground reaction force and Tampa Scale for Kinesiophobia-11 score (Spearman's r = -0.17, p = .355). On multiple regression analyses, lower preparatory vastus medialis activity during landing (beta coefficient = -0.51, p < .001) and knee pain intensity (beta coefficient = 0.57, p < .001) were significantly associated with greater Tampa Scale for Kinesiophobia-11 scores.
In athletes who have participated in sports following anterior cruciate ligament reconstruction, lower preparatory vastus medialis activity during landing and knee pain intensity are associated with greater kinesiophobia. These findings indicate that interventions to address the landing muscle activity pattern and pain control should be performed to decrease kinesiophobia after anterior cruciate ligament reconstruction.
运动恐惧症是对身体运动和活动的恐惧，已知其会影响前交叉韧带重建后重返运动和二次损伤。
确定前交叉韧带重建后运动员中着陆生物力学、膝关节疼痛和运动恐惧症之间的关联。
横断面研究。
运动医学临床中心。
本研究包括 31 名运动员，他们在初次单侧前交叉韧带重建后参加运动（年龄中位数[四分位距]：20.0 [7.0]岁；体重指数：22.2 [2.6]kg/m ；前交叉韧带重建后时间：24.0 [23.0]个月）。
不适用。
运动恐惧症采用坦帕运动恐惧症量表-11 进行测量。膝关节功能包括关节松弛度、力量和单腿跳跃距离。运动时膝关节疼痛强度采用数字评分量表进行测量。测量垂直地面反作用力，并采集单腿跳跃着陆时股直肌和半腱肌的肌电图数据。进行单变量相关分析和多元回归分析，以确定坦帕运动恐惧症量表-11 评分与结局测量之间的关系。
峰值垂直地面反作用力与坦帕运动恐惧症量表-11 评分之间无相关性（Spearman r=-0.17，p=0.355）。在多元回归分析中，着陆时预备期股直肌活动减少（β系数=-0.51，p<0.001）和膝关节疼痛强度增加（β系数=0.57，p<0.001）与坦帕运动恐惧症量表-11 评分较高显著相关。
在前交叉韧带重建后参加运动的运动员中，着陆时预备期股直肌活动减少和膝关节疼痛强度与运动恐惧症程度增加相关。这些发现表明，应该进行干预以解决着陆肌肉活动模式和疼痛控制问题，以减少前交叉韧带重建后的运动恐惧症。
