[Purpose] We investigated the effects of low-intensity pulsed ultrasound (LIPUS) irradiation of the infrapatellar fat pad (IFP) combined with therapeutic exercise for management of knee osteoarthritis (knee OA). [Participants and Methods] The study included 26 patients with knee OA, who were randomized into the LIPUS group (patients underwent LIPUS + therapeutic exercise) and the therapeutic exercise group (patients underwent sham LIPUS + therapeutic exercise). We measured changes in the patellar tendon-tibial angle (PTTA) and in IFP thickness, IFP gliding, and IFP echo intensity after 10 treatment sessions to determine the effects of the aforementioned interventions. We additionally recorded changes in the visual analog scale, Timed Up and Go Test, the Western Ontario and McMaster Universities Osteoarthritis Index, and Kujala scores, as well as range of motion in each group at the same end-point. [Results] Compared with patients in the therapeutic exercise group, those in the LIPUS group showed significant post-treatment improvements in PTTA, VAS, and Kujala scores, as well as in range of motion. [Conclusion] The combined use of LIPUS irradiation of the IFP and therapeutic exercise is a safe and effective modality to reduce IFP swelling, relieve pain, and improve function in patients with knee OA.
[目的] 我们研究了低强度脉冲超声（LIPUS）照射髌下脂肪垫（IFP）联合治疗性运动对膝关节骨关节炎（膝骨关节炎）的治疗效果。[参与者与方法] 该研究纳入了26例膝骨关节炎患者，他们被随机分为LIPUS组（患者接受LIPUS + 治疗性运动）和治疗性运动组（患者接受假LIPUS + 治疗性运动）。在10次治疗疗程后，我们测量了髌腱 - 胫骨角（PTTA）、IFP厚度、IFP滑动度和IFP回声强度的变化，以确定上述干预措施的效果。我们还记录了视觉模拟量表、计时起立行走测试、西安大略和麦克马斯特大学骨关节炎指数以及库贾拉评分的变化，以及每组在同一终点的关节活动范围。[结果] 与治疗性运动组患者相比，LIPUS组患者在治疗后PTTA、VAS和库贾拉评分以及关节活动范围方面均有显著改善。[结论] LIPUS照射IFP与治疗性运动联合使用是一种安全有效的方法，可减轻膝骨关节炎患者的IFP肿胀、缓解疼痛并改善功能。
