The purpose of this article is to describe a sonographically guided technique to perform therapeutic injection into the medial collateral ligament bursa. Scans are performed using a high-frequency linear transducer with the scan plane corresponding to the anatomic coronal plane. The transducer is positioned along the medial aspect of the knee; a 25-gauge needle is placed along the inferior border of the bursa; and a standardized therapeutic mixture (anesthetic and long-active corticosteroid) is injected. Distention of the bursa is the determining factor for a successful injection. Sonography allows confirmation of correct injection placement, resulting in increased accuracy and more successful patient outcomes.
本文旨在描述一种超声引导下向内侧副韧带滑囊进行治疗性注射的技术。使用高频线性换能器进行扫描，扫描平面与解剖冠状平面相对应。换能器沿膝关节内侧放置；将一根25号针头沿滑囊下缘放置；然后注射标准化的治疗混合物（麻醉剂和长效皮质类固醇）。滑囊扩张是注射成功的决定因素。超声检查可确认注射位置是否正确，从而提高准确性并使患者获得更好的治疗效果。
