: Notwithstanding patellofemoral pain syndrome (PFPS) being one of the most common causes of pain in the front of the knee in outpatients, few studies have shown the effects of radiofrequency on knee pain and function in this population. The aim of the present study was to determine whether outpatients diagnosed with PFPS obtained improvement in pain and function after treatment by dynamic application of monopolar dielectric diathermy by emission of radiofrequency (MDR). : An experimental study was conducted with 27 subjects with PFPS. Subjects were treated with 10 sessions of MDR in dynamic application. The visual analogue scale (VAS), the Kujala scale, the DN4 questionnaire, the lower extremity function scale (LEFS), the range of movement (ROM) in knee flexion and extension and the daily drug intake were measured pre- and post-intervention and at the time of the follow-up (six months). : Statistically significant differences were found in pain perception (VAS: F = 92.43, < 0.000, ŋ = 0.78 and DN4: F = 124.15, < 0.000, ŋ = 0.82), as well as improvements in functionality (LEFS: F = 72.42, < 0.000, ŋ = 0.74 and Kujala: F = 40.37, < 0.000, ŋ = 0.61]) and in ROM (Flexion: F = 63.15, < 0.000, ŋ = 0.71). No statistically significant changes in drug intake were found. : The present study shows that the dynamic application of MDR seems effective in reducing pain and increasing functionality and knee flexion in patients with PFPS, after a follow-up of six months.
尽管髌股疼痛综合征（PFPS）是门诊膝关节前痛的最常见原因之一，但很少有研究表明射频对该人群的膝关节疼痛和功能有影响。本研究旨在确定诊断为 PFPS 的门诊患者在接受动态应用单极介电透热疗法（发射射频）治疗后，疼痛和功能是否得到改善。
一项针对 27 例 PFPS 患者的实验研究。患者接受 10 次动态应用 MDR 治疗。在干预前、干预后和随访（6 个月）时，使用视觉模拟量表（VAS）、Kujala 量表、DN4 问卷、下肢功能量表（LEFS）、膝关节屈伸活动范围（ROM）和每日药物摄入量来测量。
在疼痛感知（VAS：F = 92.43，< 0.000，ŋ = 0.78 和 DN4：F = 124.15，< 0.000，ŋ = 0.82）以及功能改善（LEFS：F = 72.42，< 0.000，ŋ = 0.74 和 Kujala：F = 40.37，< 0.000，ŋ = 0.61）以及 ROM（屈伸：F = 63.15，< 0.000，ŋ = 0.71）方面均发现有统计学显著差异。在药物摄入方面没有发现统计学显著变化。
本研究表明，动态应用 MDR 似乎可有效减轻 PFPS 患者的疼痛，增加其功能和膝关节屈伸度，6 个月随访时效果持续。
