The purpose of this study was to investigate the feasibility of using real-time high-resolution sonography to guide an injection needle into the intra-articular space within the knee.
Eighty-nine patients with radiographically confirmed knee osteoarthritis (Kellgren-Lawrence grade 2 or 3) without an effusion were included. After sonographically guided or blind injection of hyaluronic acid (HA) and contrast dye through a medial patellar portal (MPP) into the knee joint, a radiographic image was made to ascertain whether the injected material had reached the intra-articular space.
Sonographically guided injections of HA into the knee joint had a significantly greater accuracy rate (95.6%) than blind injections (77.3%; P = .01).
Intra-articular injections via an MPP using sonographic guidance may raise the accuracy rate in knee joint injections.
本研究旨在探讨实时高分辨率超声引导膝关节腔内注射针的可行性。
89 例影像学证实的膝骨关节炎（Kellgren-Lawrence 分级 2 或 3 级）患者，关节内无积液。在膝关节经内侧髌旁入路（MPP）行透明质酸（HA）和对比染料超声引导或盲注后，行影像学检查以确定注射材料是否已进入关节腔。
HA 膝关节腔内超声引导注射的准确率（95.6%）显著高于盲注（77.3%；P =.01）。
采用超声引导经 MPP 进行关节内注射可能会提高膝关节注射的准确率。
