Intra-articular ganglion cysts of the cruciate ligaments

Intra-articular ganglion cysts of the cruciate ligaments are associated with non-specific clinical signs and symptoms. Familiarity with the MR appearances in particular is important to make an accurate diagnosis, exclude associated abnormalities, and avoid misdiagnosis.

Assessment of patellar maltracking using combined static and dynamic MRI

Between January 1995 and Jul 1997, 474 patients with anterior knee pain resistant to conservative treatment were referred for MR of the knee. The MR examination consisted of routine sequences with an additional patellofemoral dynamic examination using a technique that has been developed at this institution. The dynamic study examines both knees simultaneously, with the patient supine and the quadriceps loaded. No gating or restraint apparatus is needed. Patellar subluxation or tilt was present in 188(40 %) of cases, bilateral in 104 and unilateral in 84 cases (right 39, left 45). It was classified as mild in 51 %, moderate in 39 % and severe in 10 %. Subluxation was more prevalent in females than males (42 % vs. 37 %) and this was most obvious in the severe group where 68 % were female. In 90 knees selected at random, four measurements of patellofemoral morphology were obtained using reconstructed images from a volume gradient echo sequence. These measurements were correlated with the degree of subluxation or tilt. A tibial tubercle distance greater than 20 mm, a femoral sulcus angle greater than 150 degrees, sulcus depth less than 4 mm were specific for subluxation but no measurement proved to be sufficiently sensitive to preclude a tracking study. MRI can be used to define more precisely the anatomy of the extensor mechanism and its relationship to the femur and tibia, in both a static and dynamic setting. In this way, patients with anterior knee pain can be classified more accurately and the outcomes of treatment more reliably assessed.

关节镜下治疗膝关节半月板损伤7例分析

目的 探讨关节镜下膝关节半月板损伤治疗方法。方法 自2001年12月至2003年5月对7例膝关节半月板损伤进行关节镜下检查及治疗。7例中，右侧5例，左侧2例；内侧半月板损伤3例，外侧半月板4例。O‘Connor关节镜下损伤类型：斜形撕裂2例，水平撕裂1例，纵形撕裂1例，瓣状撕裂2例，复合撕裂1例；半月板部分切除术3例，半月板次全切除术4例。结果 7例均经随访，随访时间12～30个月，平均20个月。7例患者均于次日进行股四头肌等长训练，第3天膝关节开始屈伸活动，第7天下地行走，2周基本恢复正常膝关节活动功能，未发生关节镜器械折断在关节腔现象，无骨关节炎表现。结论 关节镜技术治疗膝关节半月板损伤具有损伤小、恢复快等优点。

MRI对痛风性膝关节炎诊断的准确性研究

目的探讨MRI对痛风性膝关节炎诊断的准确性。方法回顾性分析张家港澳洋医院2015年7月至2019年2月收治的31例慢性痛风患者膝关节双能量CT和MRI检查图像,以双能量CT为金标准,检验MRI对痛风石检出的敏感性、特异性、阳性预测值、阴性预测值和准确性。结果 4例患者行双侧膝关节双能量CT和MRI检查,共35个膝关节纳入研究。MRI对痛风石检出的特异性为0. 977(95%CI:0. 930～0. 994),敏感性为0. 648(95%CI:0. 551～0. 735),阳性预测值为96. 0%,阴性预测值为77. 0%,准确性为82. 8%。结论与双能量CT相比,MRI具有较高的特异性和准确性,对痛风性关节炎的诊断潜力较大。

后交叉韧带损伤MRI诊断指标的评价

目的评价后交叉韧带(PCL)损伤各种MRI征象的诊断价值。资料与方法分析32例经关节镜或临床诊断的PCL损伤患者MRI资料,并与57例非PCL损伤病例对照,总结PCL损伤直接和间接征象,依据各征象建立回归模型。结果正常PCL可分为"弓"形、"U"形、和"打结"形3种形态。根据PCL损伤征象建立的回归模型,其诊断的重要程度依次为PCL消失、不连续,PCL信号异常,内侧副韧带损伤,PCL增粗,三角间隙积液以及骨挫伤。结论MRI是诊断PCL损伤的重要手段。PCL损伤各征象对诊断的重要性不同,以此建立的回归模型有较强的预测能力。
