A prospective study of 564 patients was performed to assess the correlation between patellar shape as seen on a lateral radiograph and 1) patellar pain and 2) the radiologic determination of patellar height. A classification of patellar shape was developed based on the ratio of the patellar length to the length of the articular surface. Three classification types were established, including the "long-nosed," "Cyrano" type. Patients were placed into one of two groups based on the presence or absence of patellar pain. Lateral radiographs were evaluated for patellar height using two published indices. A significantly larger portion of Type II and Type III patellae was found in patients with patellar pain. Moreover, accepted measures of patellar height have to be used with caution in the presence of unusual patellar shapes.
对564例患者进行了一项前瞻性研究，以评估侧位X线片上所见的髌骨形状与1）髌骨疼痛和2）髌骨高度的影像学测定之间的相关性。基于髌骨长度与关节面长度的比值制定了髌骨形状分类。建立了三种分类类型，包括“长鼻”型、“大鼻子”型。根据是否存在髌骨疼痛，将患者分为两组。使用两个已发表的指标对侧位X线片进行髌骨高度评估。在有髌骨疼痛的患者中发现II型和III型髌骨的比例明显更高。此外，在存在异常髌骨形状的情况下，必须谨慎使用公认的髌骨高度测量方法。
