膝前部痛是青年人膝部疾病中最常见的一种,髌软骨软化常伴有膝前部疼痛。通常认为皱襞是正常的胚胎残留物,永存至成人期,当其增厚时也有病理意义。作者对23例有髌软骨软化和皱襞,并经关节镜行外科治疗效果良好的病人进行CT关节造影和关节镜检查,且把两种检查的敏感性、特异性和准确性进行计算比较,应用Kappa指数确定CT关节造影和关节镜对皱襞增厚的诊断是否一致,X~2 Anterior knee pain is the most common form of knee disease in young people. Patella cartilage is often accompanied by anterior knee pain. It is commonly thought that folds are normal embryonic residues that persist to adulthood and have pathological significance when they are thickened. The authors performed CT arthroscopy and arthroscopy on 23 patients with patellar cartilage softening and folds and good surgical outcomes by arthroscopy. Comparisons of the sensitivities, specificities, and accuracies of the two examinations were performed. Kappa index to determine CT joint arthroscopy and arthroscopy on the diagnosis of folds thickening is consistent, X ~ 2
