工作背景：髌股疼痛综合征是最常见的慢性膝关节损伤之一;然而，很少有研究来确定这种损伤的危险因素。假设：下肢运动学和动力学改变、力量下降和姿势测量改变将是危险因素。研究设计：队列研究（预后）;证据等级，2.方法：共有1597名参与者参加了这项调查，并从他们入组之日起进行前瞻性随访。（2005年7月、2006年7月或2007年7月）至2008年1月，最长随访2.5年。每个参与者都在美国海军学院大一前的夏天接受了基线数据收集。基线数据收集包括3维运动分析在跳跃着陆任务，6下肢等长力量测试，和姿势对齐测量（舟骨下降和Q角）。结果：髌股关节疼痛综合征的发展的危险因素包括膝关节屈曲角下降，垂直地面反作用力下降，增加髋关节内旋角在跳跃着陆任务。此外，减少股四头肌和腘绳肌的力量，增加髋关节外旋力量，增加舟骨下降的风险因素为髌股疼痛syndrome.Conclusion的发展：多个可修改的风险因素髌股疼痛综合征疼痛已被确定在这项调查中。为了降低这种慢性损伤的发生率，髌股疼痛综合征的危险因素需要在损伤预防计划中有针对性。
Background: Patellofemoral pain syndrome is one of the most common chronic knee injuries; however, little research has been done to determine the risk factors for this injury.Hypothesis: Altered lower extremity kinematics and kinetics, decreased strength, and altered postural measurements will be risk factors.Study Design: Cohort study ( prognosis); Level of evidence, 2.Methods: A total of 1597 participants were enrolled in this investigation and prospectively followed from the date of their enrollment ( July 2005, July 2006, or July 2007) through January 2008, a maximum of 2.5 years of follow-up. Each participant underwent baseline data collection during their pre-freshman summer at the United States Naval Academy. Baseline data collection included 3-dimensional motion analysis during a jump-landing task, 6 lower extremity isometric strength tests, and postural alignment measurements ( navicular drop and Q angle).Results: Risk factors for the development of patellofemoral pain syndrome included decreased knee flexion angle, decreased vertical ground-reaction force, and increased hip internal rotation angle during the jump-landing task. Additionally, decreased quadriceps and hamstring strength, increased hip external rotator strength, and increased navicular drop were risk factors for the development of patellofemoral pain syndrome.Conclusion: Multiple modifiable risk factors for patellofemoral pain syndrome pain have been identified in this investigation. To decrease the incidence of this chronic injury, the risk factors for patellofemoral pain syndrome need to be targeted in injury prevention programs.
