Evaluation of the patient with patellofemoral complaints requires a comprehensive physical and radiologic investigation. The tangential view is most helpful in the evaluation of such patellofemoral disorders as chondromalacia, lateral patellar compression syndrome, and recurrent subluxation or dislocation. Commonly utilized tangential views include those described by Hughston, Merchant, Laurin, and Ficat. Multiple calculations available for quantitation of abnormal tangential views include the sulcus angle, congruence angle, lateral patellofemoral angle, patella index, and patellofemoral index. Lateral radiographic views commonly utilized to evaluate the patellofemoral joint for patella alta or infera include those described by Blumensaat, Labelle and Laurin, and Insall and Salvati. Utilization of all of the available patellofemoral radiographic views and calculations is impractical and unnecessary. However, to ensure diagnostic accuracy, a routine consisting of a reproducible radiographic technique and various, easily performed calculations that aid in diagnosis must be adopted.
对患有髌股关节疾病的患者进行评估需要全面的体格检查和影像学检查。切线位视图对评估诸如髌骨软化症、外侧髌股关节挤压综合征以及复发性半脱位或脱位等髌股关节疾病最有帮助。常用的切线位视图包括休斯顿、梅钱特、劳兰和菲卡特所描述的视图。可用于定量异常切线位视图的多种计算方法包括沟角、适合角、外侧髌股角、髌骨指数和髌股指数。常用于评估髌股关节高位或低位髌骨的外侧X线视图包括布卢门萨特、拉贝尔和劳兰以及英萨尔和萨尔瓦蒂所描述的视图。使用所有可用的髌股关节X线视图和计算方法既不实际也没有必要。然而，为确保诊断准确性，必须采用一套由可重复的放射学技术和有助于诊断的各种易于执行的计算方法组成的常规检查方法。
