目的:比较X线及MRI对诊断早期髌骨软化症的价值.方法对35例经临床证实的早期髌骨软化症患者回顾分析其X线和MRI表现,寻找早期髌骨软化症的证据.结果 MRI无阳性表现4例,有软骨改变及轻微软骨下骨质改变的31例,诊断准确率88.57%; X线表现正常的12例,髌骨后缘轻微骨质改变的23例,诊断准确率65.71%;两者比较有统计学意义.结论 MRI对于早期髌骨软化症的诊断价值优于X线. “,”Objective To compare the value of X-ray and MRI for the early diagnosis of chondromalacia patellae.Methods In 35 patients with clinical conifrmed early patella softening,analysis of the X-ray and MRI findings to look for evidence of chondromalacia patella.ResultsMRI had no positive findings in 4 cases,31 cases of cartilage and subchondral bone changes change slightly, the accuracy rate of diagnosis in 88.57%;X-ray manifestations of 12 cases of normal,23 cases of patella bone trailing edge change slightly,the accuracy rate of diagnosis in 65.71%;The comparison between the two had statistical signiifcance.ConclusionMRI is superior to X-ray in diagnosis of early chondromalacia patella.
