PURPOSE
To evaluate the alpha angle of the hip in patients with noncontact anterior cruciate ligament (ACL) injury and compare it with patients without injury. In addition, external and internal rotation of the hip was assessed and correlated with the alpha angle.
METHODS
The alpha angle of the ipsilateral hip was assessed in 41 subjects with non-contact ACL tear and compared with 39 subjects with no tear. The external and internal rotation of the ipsilateral hip was also evaluated.
RESULTS
The alpha angle was larger in subjects with noncontact ACL injury. The mean was 70.31° (±13.92°) compared with 58.55° (±13.95°) in the control group (p < 0.001). The groups were similar when considering the external, internal, and sum of rotation of the ipsilateral hip. There was no correlation between the alpha angle and decreased rotational range of motion of the hip in either group (p > 0.05).
CONCLUSION
Patients with noncontact ACL injury presented a greater alpha angle when compared with the group without tear. There was no difference in the rotational mobility of the hip between groups, nor was there a correlation between the increase in the alpha angle and the decrease in the rotational mobility of the hip.
目的
评估非接触性前交叉韧带（ACL）损伤患者的髋关节α角，并与未受伤患者进行比较。此外，评估髋关节的外旋和内旋情况，并将其与α角进行关联分析。
方法
对41例非接触性ACL撕裂患者的患侧髋关节α角进行评估，并与39例未撕裂患者进行比较。同时，对患侧髋关节的外旋和内旋情况也进行了评估。
结果
非接触性ACL损伤患者的α角更大。其平均值为70.31°（±13.92°），而对照组为58.55°（±13.95°）（p < 0.001）。在考虑患侧髋关节的外旋、内旋及旋转总和时，两组相似。两组中α角与髋关节旋转活动度降低之间均无相关性（p > 0.05）。
结论
与未撕裂组相比，非接触性ACL损伤患者的α角更大。两组之间髋关节的旋转活动度无差异，α角增加与髋关节旋转活动度降低之间也无相关性。
