Background: Anterior knee pain is one of the most common orthopedic knee disorders. The pain could be caused by an excessive lateral patellar displacement that leads to strain on the retro-patellar subchondral bone. Methods: In this prospective case study, the effectiveness of electro-acupuncture with direct current in three male adult patients with anterior knee pain was documented with magnetic resonance images. The patients were treated using nine acupuncture needles inserted into the iliotibial band with an electric current of 12 volts and 200 micro-amperes applied for 30 seconds; the treatment was repeated weekly 6 times. Results: After 6-weeks treatment, a comparison between pre- and post-treatment images reflected that the lateral patellar displacements were reduced, those biomechanical changes likely contributed to a decrease in numeric pain rating scale reported by the patients. Conclusion: The positive finding for the electro-acupuncture in the present study warranted further investigation.

背景:前膝關節疼痛是常見的骨科膝關節疾病。這種疼痛可能是由於過度的髕骨外移，導致髕股關節內壓增加引起。方法：在這項前瞻性案例研究中，三位男性成年前膝關節疼痛患者接受直流電針治療，電針療效由核磁共振圖像引證。電針治療程序為，9根針灸針插入患者的髂脛束，治療電流為12伏，200微安，施加30秒；治療每週1次重複6週。結果：治療6週後，治療前和治療後核磁共振圖像的比較反映出髕骨外移減少，這些生物力學改變應與患者疼痛減少有關。結論：基於上述正面發現，直流電針治療前膝關節疼痛的效果值得進一步研究。
