To compare the accuracy rates between ultrasound (US)-guided and blind knee intra-articular injection via the suprapatellar bursa.
Ninety-nine patients with radiographically confirmed knee osteoarthritis (Kellgren/Lawrence grade 2 or 3) without effusion were included. Fifty patients were assigned to the US-guided injection group and 49 to the blind injection group. After a US-guided or blind injection of hyaluronic acid (HA) and contrast dye through the suprapatellar bursa into the knee joint, a radiographic image was obtained in each case to ascertain whether all injected material had reached the intra-articular space.
US-guided HA injection exhibited a significantly greater accuracy (48 of 50 knees, 96.0%) than blind injection (41 of 49 knees, 83.7%).
Intra-articular injections through the suprapatellar bursa under US guidance increased the accuracy of knee joint injections.
比较超声(US)引导下经髌上囊进行膝关节腔内注射与盲目注射的准确率。
纳入99例经影像学证实为膝关节骨关节炎(凯尔格伦/劳伦斯分级2级或3级)且无积液的患者。50例患者被分配至超声引导注射组,49例患者被分配至盲目注射组。在超声引导下或盲目经髌上囊将透明质酸(HA)和造影剂注射入膝关节后,对每例患者进行影像学检查,以确定所有注射材料是否均已进入关节腔。
超声引导下HA注射的准确率(50例膝关节中的48例,96.0%)显著高于盲目注射(49例膝关节中的41例,83.7%)。
在超声引导下经髌上囊进行膝关节腔内注射可提高注射的准确率。
