To evaluate the beliefs of people with patellofemoral pain (PFP) about their condition's development and persistence, and treatment options, before and after self-directed access to a web-based education platform.
Pre- and post-intervention trial.
Fifty-eight people with PFP completed custom questionnaires (open-ended and multiple choice) before and 6 weeks after accessing the "My Knee Cap" web-based education platform. Questions covered beliefs about causes and persistence of pain, effectiveness of treatments, and willingness to undergo surgery. Open-ended responses were analysed thematically. McNemar's test with Yates correction compared changes between pre- and post-intervention for multiple choice questions.
At baseline and 6 weeks, PFP onset was primarily attributed to loading. At baseline, pain persistence was linked to loading, structure, and muscle impairments, with muscle impairments being replaced by sedentary behaviour at the 6-week follow-up. At baseline, most participants (69%-81%) believed that taping, bracing, foot orthoses, and exercises were effective treatment options. Fewer participants (16%-22%) believed that dry needling, injections, ultrasound, and surgery were effective. At 6 weeks, beliefs about the effectiveness of exercise (16% increase, ES = 0.15), injections (13% decrease, ES = 0.44), and ultrasound (15% decrease, ES = 0.50) changed. At baseline and 6 weeks, most participants (93%-95%) believed exercise was more effective than surgery, and 46%-59% were willing to undergo surgery if imaging revealed abnormalities.
Beliefs about the causes and persistence of PFP centred on loading and pathoanatomical factors, remaining largely unchanged after self-directed web-based education. Web-based education may help to promote the benefits of exercise and reduce beliefs that injection and ultrasound are helpful.
评估髌股疼痛（PFP）患者在自主访问基于网络的教育平台前后，对其病情发展、持续存在的看法以及治疗选择。
干预前后试验。
58名PFP患者在访问“我的膝盖骨”基于网络的教育平台之前和之后6周完成了定制问卷（开放式和多项选择题）。问题涵盖对疼痛原因和持续存在的看法、治疗效果以及接受手术的意愿。对开放式回答进行主题分析。采用带有耶茨校正的麦克尼马尔检验比较干预前后多项选择题的变化。
在基线和6周时，PFP的发作主要归因于负荷。在基线时，疼痛持续存在与负荷、结构和肌肉损伤有关，在6周随访时，肌肉损伤被久坐行为所取代。在基线时，大多数参与者（69%-81%）认为贴扎、支具、足部矫形器和运动是有效的治疗选择。较少参与者（16%-22%）认为干针疗法、注射、超声和手术是有效的。在6周时，对运动效果（增加16%，效应量=0.15）、注射（减少13%，效应量=0.44）和超声（减少15%，效应量=0.
