【摘要】：[目的]提出关节镜及核磁共振成像(magnetic resonance imaging,MRI)诊断骨性关节炎(osteoarthrisis,OA)患者膝关节软骨损伤的分级法,探讨MRI在诊断关节软骨损伤中的价值。[方法]回顾性分析行关节镜检查的123例骨性关节炎患者的膝关节术前MRI表现;按部位将膝关节软骨分为6处;根据形态和信号改变,结合损伤部位,将膝关节软骨损伤在关节镜与MRI的表现加以分析并分级;以关节镜所见为参考标准,计算MRI诊断各级软骨损伤的敏感性、特异性、准确性。[结果]在关节镜及MRI上,膝关节软骨损伤均可分为Ⅰ~Ⅳ级;在738处软骨中,损伤505处(68.43%),其中髌股关节最多,外侧胫股关节最少,且损伤以Ⅲ~Ⅳ级为主;关节镜与MRI判断软骨损伤差异具有统计学意义(χ~2=107.52,P0.001)。MRI诊断软骨损伤总的敏感性、特异性、准确性分别为70.10%、93.13%、77.37%。[结论]骨性关节炎患者膝关节软骨损伤在关节镜及MRI的表现可被分为4级;软骨损伤以髌股关节最多;MRI诊断骨性关节炎软骨损伤的特异性较高,但敏感性和准确性相对较低。
[Abstract]:[Objective] to study the diagnosis of osteoarthrisis by arthroscopy and magnetic resonance imaging (resonance). To evaluate the value of MRI in the diagnosis of articular cartilage injury. [Methods: the preoperative MRI findings of 123 patients with osteoarthritis underwent arthroscopic examination were retrospectively analyzed. The articular cartilage was divided into 6 parts according to the position. According to the changes of morphology and signal, combined with the injury site, the articular cartilage injuries were analyzed and graded under arthroscopy and MRI. The sensitivity, specificity and accuracy of MRI in the diagnosis of cartilage injury at all levels were calculated according to arthroscopy. [Results: on arthroscopy and MRI, cartilage injury of knee joint can be classified into grade 鈪，
