Abstract：
UNASSIGNED: Cam morphology develops during skeletal growth, but its influence on cartilage and the labrum in high-impact athletes later in life is unknown.
UNASSIGNED: To (1) explore the association between the presence and duration of cam morphology during adolescence and the cartilage and labral status 7 to 12 years later and (2) report the prevalence of cartilage loss and labral damage in a population of young male athletes (<32 years old) who played professional soccer during skeletal growth.
UNASSIGNED: Cohort study (Prognosis); Level of evidence, 2.
UNASSIGNED: A total of 89 healthy male academy soccer players from the Dutch soccer club Feyenoord (aged 12-19 years) were included at baseline. At baseline and 2.5- and 5-year follow-ups, standardized supine anteroposterior pelvis and frog-leg lateral radiographs of each hip were obtained. At 12-year follow-up, magnetic resonance imaging of both hips was performed. Cam morphology was defined by a validated alpha angle ≥60° on radiographs at baseline or 2.5- or 5-year follow-up when the growth plates were closed. Hips with the presence of cam morphology at baseline or at 2.5-year follow-up were classified as having a \"longer duration\" of cam morphology. Hips with cam morphology only present since 5-year follow-up were classified as having a \"shorter duration\" of cam morphology. At 12-year follow-up, cartilage loss and labral abnormalities were assessed semiquantitatively. Associations were estimated using logistic regression, adjusted for age and body mass index.
UNASSIGNED: Overall, 35 patients (70 hips) with a mean age of 28.0 ± 2.0 years and mean body mass index of 24.1 ± 1.8 participated at 12-year follow-up. Cam morphology was present in 56 of 70 hips (80%). The prevalence of cartilage loss was 52% in hips with cam morphology and 21% in hips without cam morphology (adjusted odds ratio, 4.52 [95% CI, 1.16-17.61]; P = .03). A labral abnormality was present in 77% of hips with cam morphology and in 64% of hips without cam morphology (adjusted odds ratio, 1.99 [95% CI, 0.59-6.73]; P = .27). The duration of cam morphology did not influence these associations.
UNASSIGNED: The development of cam morphology during skeletal growth was associated with future magnetic resonance imaging findings consistent with cartilage loss in young adults but not with labral abnormalities.

摘要：
■凸轮形态在骨骼生长过程中发育，但是它对高冲击力运动员以后的软骨和唇板的影响是未知的。
■（1）探讨青春期凸轮形态的存在和持续时间与7至12年后的软骨和唇状态之间的关系，以及（2）报告软骨损失的患病率在骨骼生长期间参加职业足球的年轻男性运动员（<32岁）中的唇损伤。
■队列研究（预后）；证据水平，2.
■基线时，共有89名来自荷兰足球俱乐部费耶诺德（12-19岁）的健康男性学院足球运动员。在基线和2.5年和5年随访时，获得了每个髋关节的标准化仰卧前后骨盆和青蛙腿外侧X光片。在12年的随访中，对两髋进行磁共振成像.当生长板关闭时，在基线或2.5年或5年随访时，通过X射线照片上验证的α角≥60°来定义凸轮形态。基线时或2.5年随访时存在凸轮形态的髋关节被归类为凸轮形态持续时间较长。自5年随访以来，仅存在凸轮形态的髋关节被归类为凸轮形态的“较短持续时间”。在12年的随访中，半定量评估软骨损失和唇异常。使用逻辑回归估计关联，根据年龄和体重指数进行调整。
■总的来说，在12年的随访中，35例患者（70髋）的平均年龄为28.0±2.0岁，平均体重指数为24.1±1.8。凸轮形态存在于70个臀部中的56个(80%)。软骨丢失的患病率在有凸轮形态的臀部为52％，在没有凸轮形态的臀部为21％（调整后的比值比，4.52[95%CI，1.16-17.61]；P=0.03）。77％的有凸轮形态的臀部和64％的无凸轮形态的臀部存在唇异常（调整后的比值比，1.99[95%CI，0.59-6.73]；P=.27）。凸轮形态的持续时间不影响这些关联。
骨骼生长过程中凸轮形态的发展与未来的磁共振成像发现相关，与年轻人的软骨丢失一致，但与唇异常无关。
