The relationship between structural foot deformities and excessive subtalar joint pronation as being contributory to patellofemoral pain has not been well documented. It was the purpose of this study to assess the rearfoot posture in patients diagnosed with patellofemoral pain compared with a normal population. In addition, the intratester reliability in obtaining rearfoot measurements was assessed for right and left sides in 21 normal subjects. A goniometer was used to measure rearfoot posture in 30 female subjects (15 with patellofemoral pain and 15 controls). Measurements were taken with the subjects prone and the subtalar joint in neutral. Intraclass correlation coefficients were good for both the right and left measurements (.87 and .86, respectively). A small but significant increase in rearfoot varus was found in the patellofemoral pain group compared with the control group (8.9 vs. 6.8 degrees; p = .0002). These results suggest that increased rearfoot varus may be a contributing factor in patellofemoral pain and should be assessed when evaluating the events at the subtalar joint and the lower extremity. In addition, it has been demonstrated that consistent rearfoot measurements can be obtained by an individual clinician.
足部结构畸形与距下关节过度旋前之间的关系被认为是导致髌股关节疼痛的原因，但相关文献记载并不充分。本研究旨在评估与正常人群相比，被诊断为髌股关节疼痛的患者的后足姿势。此外，还评估了21名正常受试者左右两侧后足测量结果的测试者内可靠性。使用测角仪对30名女性受试者（15名患有髌股关节疼痛，15名作为对照）的后足姿势进行测量。测量时受试者俯卧，距下关节处于中立位。组内相关系数在左右测量中均良好（分别为0.87和0.86）。与对照组相比，髌股关节疼痛组的后足内翻有小幅但显著的增加（8.9度对6.8度；p = 0.0002）。这些结果表明，后足内翻增加可能是髌股关节疼痛的一个促成因素，在评估距下关节和下肢情况时应予以评估。此外，研究还表明，个体临床医生能够获得一致的后足测量结果。
