Patellofemoral pain is one of the most common disorders affecting the knee. Forefoot varus and excessive subtalar pronation can be associated with patellofemoral pain. Foot orthotics may produce an improvement in symptoms.
The aim of this study was to test whether patellofemoral pain is improved after four weeks of using custom-made foot orthoses.
Clinical trial without control group.
Twenty-one subjects with patellofemoral pain were given custom-made foot orthoses (2-mm thick polypropylene and 4-mm thick polyethylene foam liner of 45 shore A hardness). Patellofemoral pain was evaluated with a visual analogue scale before applying the treatment, and at two weeks and four weeks follow-up. At the two-week check-up, a forefoot varus posting was added to the orthoses.
Improvements in patellofemoral pain was significant in all comparisons: initial pain with pain at the two-week check-up (P < 0.001), initial pain with pain at four weeks (P < 0.001), and pain at two weeks with pain at four weeks (P < 0.001). The effect size was large in all comparisons.
For the participants in this study, the custom-made foot orthoses were found to be an effective conservative treatment to reduce the symptoms of patellofemoral pain.
髌股疼痛是影响膝关节的最常见病症之一。前足内翻和距下关节过度旋前可能与髌股疼痛有关。足部矫形器可能会改善症状。
本研究的目的是测试定制足部矫形器使用四周后髌股疼痛是否得到改善。
无对照组的临床试验。
21名患有髌股疼痛的受试者被给予定制足部矫形器（2毫米厚的聚丙烯和4毫米厚、邵氏A硬度为45的聚乙烯泡沫衬垫）。在进行治疗前、随访两周和四周时，用视觉模拟量表评估髌股疼痛情况。在两周检查时，在矫形器上增加了前足内翻矫正。
在所有比较中，髌股疼痛均有显著改善：初始疼痛与两周检查时的疼痛相比（P < 0.001），初始疼痛与四周时的疼痛相比（P < 0.001），以及两周时的疼痛与四周时的疼痛相比（P < 0.001）。所有比较中的效应量都很大。
对于本研究中的参与者，发现定制足部矫形器是减轻髌股疼痛症状的一种有效的保守治疗方法。
