ObjectiveTo observe the clinical efficacy of ultrasound-guided acupuncture combined with functional rehabilitation in the treatment of pes anserinus bursitis caused by athletic training.MethodsA total of 50 outpatients with pes anserinus bursitis of knee joint caused by athletic training who visited Department of Rehabilitation Medicine of our hospital from May 2019 to May 2020 were enrolled, and then they were randomly divided into observation group (25 cases) and control group (25 cases). The patients in the observation group were treated with ultrasound-guided acupuncture combined with functional rehabilitation, and those in the control group were treated with blind puncture local block combined with functional rehabilitation. The pain of patients before and after treatment was evaluated by visual analogue scale (VAS), the knee joint function was evaluated by international general Lysholm score, the quality of life was assessed by quality of life scale (QOL), and the changes of inflammatory reaction in the lesion area were observed by ultrasonography and far-infrared thermal imaging.ResultsThere were no significant differences in the general data (such as gender, age, or course of disease), VAS score, Lysholm score, or QOL score between the 2 groups before the treatment (all P > 0.05). After treatment, the VAS scores of both groups were significantly lower than those before treatment (both P < 0.05), and the Lysholm and QOL scores were significantly higher than those before treatment (all P < 0.05). After treatment, the VAS score of the observation group was significantly lower than that of the control group (P < 0.05), and the Lysholm and QOL scores were significantly higher than those of the control group (both P < 0.05). After treatment, the sonogram showed that the blood flow signal in the lesion area of the observation group was reduced or disappeared, and the far-infrared thermal imaging showed that the body surface temperature at the medial condyle of tibia returned to normal. After treatment, the total efficiency of the observation group was significantly higher than that of the control group (96% [24/25] vs 68% [17/25], P < 0.05).ConclusionUltrasound-guided acupuncture combined with functional rehabilitation can effectively relieve the pain and promote the recovery of knee joint function of patients with pes anserinus bursitis caused by athletic training, with good clinical feasibility and safety.
