To prospectively determine gait-related risk factors for patellofemoral pain.
A prospective cohort study.
Male and female recruits of the Belgian Royal Military Academy during a 6-week basic military training period.
Eighty-four officer cadets (65 men, 19 women), who entered the Military Academy and were without a history of any knee or lower-leg complaints, participated in the study.
Before the start of the 6-week basic military training period, plantar pressure measurements during walking were performed. During the basic military training period, patellofemoral complaints were diagnosed and registered by a sports medicine physician.
Plantar pressure measurements during walking were performed using a footscan pressure plate (RsScan International).
During the 6-week training period, 36 subjects developed patellofemoral pain (25 male and 11 female). Logistic regression analysis revealed that subjects who developed patellofemoral pain had a significantly more laterally directed pressure distribution at initial contact of the foot, a significantly shorter time to maximal pressure on the fourth metatarsal, and a significantly slower maximal velocity of the change in lateromedial direction of the center of pressure during the forefoot contact phase.
Our findings suggest that the feet of the persons who developed anterior knee pain have a heel strike in a less pronated position and roll over more on the lateral side compared with the control group. The results of this study can be considered valuable in identifying persons at risk for patellofemoral pain.
前瞻性确定髌股关节疼痛的步态相关危险因素。
前瞻性队列研究。
比利时皇家军事学院男女新兵在为期6周的基础军事训练期间。
84名军官学员（65名男性，19名女性），他们进入军事学院且无任何膝关节或小腿疾病史，参与了本研究。
在6周基础军事训练期开始前，进行行走时的足底压力测量。在基础军事训练期间，由运动医学医生诊断并记录髌股关节疾病。
使用足部扫描压力板（RsScan International）进行行走时的足底压力测量。
在6周训练期间，36名受试者出现髌股关节疼痛（25名男性和11名女性）。逻辑回归分析显示，出现髌股关节疼痛的受试者在足部初始接触时压力分布明显更偏向外侧，第四跖骨达到最大压力的时间明显更短，在前足接触阶段压力中心内外侧方向变化的最大速度明显更慢。
我们的研究结果表明，与对照组相比，出现前膝疼痛的人的足部在足跟触地时内旋程度较小，且在外侧滚动更多。本研究结果对于识别髌股关节疼痛风险人群具有重要价值。
