PDFAbstract
Objective To compare the clinical CT and MRI diagnosis of knee joint meniscus and articular cartilage injury detection rate, and discuss the clinical diagnosis value of reference. Methods Review the comparison and analysis of the hospital in 2013 September-2014 June hospitalized during the period because of knee meniscus and articular cartilage injury in 150 patients who underwent CT and MRI scan in the diagnosis and the image characteristics of typical, clear method (articular cartilage injury of meniscus injury in 152, 149) clinical detection rate and detection rate, respectively with arthroscopy in comparison, and carries on statistics analysis. Results the observation group cartilage injury clinical stage IV and meniscus injury grade detection rate was significantly higher than that of the control group (P<0.05), statistically significant differences with arthroscopy, the detection rate of no significant difference (P<0.05). Controlled clinical group IV and cartilage injury of meniscus injury grade detection rate was significantly lower than the detection rate of arthroscopy (P<0.05), with significant difference. Conclusion MRI in the diagnosis of stage IV and III articular cartilage injury of meniscus injury was higher than that of CT diagnosis.

Introduction
膝关节是人体中最为复杂和重要的结构之一，其主要由骨、关 节、半月板及韧带、肌腱和肌肉等构成[1]。关节软骨是一层覆盖于关 节表面的透明软骨组织，表面平滑且略显淡蓝色光泽，主要在维持正 常关节活动过程中起作用，较易因剧烈运动而发生损伤。半月板损伤 在临床上也占有较大比例。轻度早期半月板或软骨损伤在及时发现后 可进行保守治疗来减轻病征，抑或治愈，但是病变若深入发展则将导 致不可逆损伤。因此，采用无创伤性且可靠性高的手段诊断半月板或 关节软骨损伤已成为临床上的迫切需要。
