PURPOSE/BACKGROUND: Patellofemoral pain (PFP) is a common knee conditions experienced by adolescents and young adults, seen particularly in women. Clinicians and researchers need to understand how proximal, local, or distal factors may influence the development of PFP and affect individuals once they have developed PFP. Proximal factors are the focus of recent studies and the purpose of this systematic review was to determine if females with PFP have hip muscle strength or endurance deficits when compared to their unaffected leg and to comparison groups.
METHODS
A systematic review was conducted to identify relevant studies in the databases PubMed, PEDro, ScienceDirect and EBSCOhost up to June 2013. Data including study design, participants demographic data, and assessments of hip muscle strength or endurance were extracted from individual trials. The mean differences of hip muscles strength or endurance between females with PFP and healthy controls or unaffected side were extracted or calculated from individual trials and, when possible, a meta-analysis was performed.
RESULTS
Ten cross-sectional studies were included in this review. Concerning isometric strength, pooled data reported deficit in hip abduction, extension, external rotation and flexion but no deficit in adduction and internal rotation when compared with healthy controls. When compared with the unaffected side, deficit in hip abduction was reported in two studies and deficit in extension and external rotation in one study. Studies with isokinetic strength evaluation reported deficit in abduction but contradictory results for extensors and rotators in females with PFPS. Finally, one study reported hip endurance deficit in extension and one found no significant differences in hip endurance compared to control subjects.
CONCLUSION
The results of this systematic review confirm that females with PFPS have deficit in hip muscle strength compared with healthy controls and the unaffected side but are contradictory concerning endurance.

目的/背景：髌股疼痛（PFP）是青少年和年轻人常见的膝关节疾病，在女性中尤为常见。临床医生和研究人员需要了解近端、局部或远端因素如何影响PFP的发展，以及在个体患上PFP后这些因素会如何影响他们。近端因素是近期研究的重点，本系统评价的目的是确定与未受影响的腿及对照组相比，患有PFP的女性是否存在髋部肌肉力量或耐力不足。
方法
进行一项系统评价，以识别截至2013年6月在PubMed、PEDro、ScienceDirect和EBSCOhost数据库中的相关研究。从各个试验中提取包括研究设计、参与者人口统计学数据以及髋部肌肉力量或耐力评估的数据。从各个试验中提取或计算患有PFP的女性与健康对照组或未受影响侧之间髋部肌肉力量或耐力的平均差异，并在可能的情况下进行荟萃分析。
结果
本评价纳入了10项横断面研究。关于等长力量，汇总数据显示与健康对照组相比，髋外展、伸展、外旋和屈曲存在不足，但内收和内旋没有不足。与未受影响侧相比，两项研究报告了髋外展不足，一项研究报告了伸展和外旋不足。进行等速力量评估的研究报告了外展不足，但对于患有髌股疼痛综合征（PFPS）的女性，伸肌和旋转肌的结果相互矛盾。最后，一项研究报告了伸展时髋部耐力不足，另一项研究发现与对照组相比髋部耐力无显著差异。
结论
本系统评价的结果证实，与健康对照组和未受影响侧相比，患有PFPS的女性髋部肌肉力量不足，但在耐力方面存在矛盾。
