摘　　要：目的:研究青少年复发性髌骨半脱位的CT诊断方法。方法:从1986年11月～2002年5月共收治复发性髌骨半脱位的患者31例。另选50例年龄在15～18岁之间的正常青少年女性作为对照。两组人群均经仔细询问病史、全面的临床查体、X线检查及屈膝20度的髌股关节CT扫描,并在CT扫描片上测量外侧髌股角、髁间沟角、和谐角;比较两组CT扫描结果。结果:(1)屈膝20度的髌股关节CT扫描上,两组股骨髁间沟角的平均值比较,差异无统计学意义(t=0.77,P>0.05);两组外侧髌股角的平均值比较,差异有统计学意义(t=20.78,P<0.05);两组和谐角的平均值比较,差异有统计意义(t=30.62,P<0.05);且3个指标相互独立无相互关联关系,说明这3个指标尤其是后二者是CT诊断青少年RSP的重要指标。结论:屈膝20度的髌股关节CT扫描是诊断青少年复发性髌骨半脱位的重要辅助手段。Objective： To investigate computed tomography diagnosis methods of recurrent subluxation of patellar in adolescent. Methods： Thirty-one patient suffering from recurrent subluxation of patellar in adolescent were recieved treatment from Novumber 1986 to May 2002. Additional, 50 female normal adolescent with age of 15418 years were selected as control. In both the control subject and the patients, a detailed history was recorded and a completely physical examination was done, they were examined using roentgenograms of the patellofemoral joint, as well as computed tomography scans that were made with the knee in 20 degrees of flexion; computed tomography scans measurement of the lateral patellofemoral angle （LPA）, the sulcus angle （SA） and the congruence angle （CA） were evaluated in two groups. Results： In the computed tomography scans imagings, comparing the average of the sulcus angle, the difference was not statistically significant （t = 0.77, P〉0.05） ;comparing the average of the lateral patellofemoral angle,the difference was statistically significant （t = 20.78, P〈0.05） ;comparing the average of the congruence angle, the difference was statistically significant （t = 30.62, P 〈0.05）. Conclusion： The computed tomography scans that were made with the knee in 20 degrees of flexion was important means while diagnosing the recurrent subluxation of patellar.
