To compare the accuracy and efficacy of ultrasound (US)-guided versus blind pes anserinus bursa (PAB) injection in patients with pes anserinus tendinobursitis (PATB).
Forty-seven patients with clinically diagnosed PATB were randomly assigned to a US-guided group or a blind group of steroid injection. In the US-guided group, the injectate was delivered under sonographic visualization. In the blind group, the conventional technique was used without any visual guidance. After the PAB injection, the injectate location was identified using US in both groups. Treatment effects were assessed using the visual analogue scale (VAS) of knee tenderness. Outcomes were measured before, 1 week and 4 weeks after the injection.
Both groups showed pain relieving at 1 week and 4 weeks after the injection. The injectate in the US guided group were found to be accurately at the PAB in all subjects, whereas blind group were found to be just in 4 of 22 subjects. The US-guided group showed significant improvement of both of VAS scores compared to the blind group at 1 week and 4 weeks after the injection (P < .05).
Our results suggest that US-guided PAB injection is more accurate and effective than blind injection in patients with PATB.
比较超声（US）引导下与盲目鹅足滑囊（PAB）注射治疗鹅足肌腱滑囊炎（PATB）患者的准确性和疗效。
47例临床诊断为PATB的患者被随机分为US引导组或盲目类固醇注射组。在US引导组中，注射剂在超声可视化下注入。在盲目组中，采用传统技术且无任何视觉引导。PAB注射后，两组均使用US确定注射剂位置。使用膝关节压痛视觉模拟量表（VAS）评估治疗效果。在注射前、注射后1周和4周测量结果。
两组在注射后1周和4周均显示疼痛缓解。在US引导组中，所有受试者的注射剂均准确注入PAB，而在盲目组的22名受试者中只有4名如此。与盲目组相比，US引导组在注射后1周和4周时VAS评分均有显著改善（P < 0.05）。
我们的结果表明，在PATB患者中，US引导下的PAB注射比盲目注射更准确、更有效。
