This study is based on the evaluation of 250 arthrographies of the patellofemoral joint ("défilé" arthrographs in Ficat's terminology) which were performed because of clinical suspicion of chondropathia patellae and which could be controlled intraoperatively in 30 cases, as well as on examinations employing an etching paste as used in metallurgy and performed on 20 knee-joints of corpses. 46% of the arthrographies showed a ridge-shaped cartilaginous thickening which was not pre-modelled in the osseous structure and which separated the medial facette into a paramedian and a marginal segment and correlated with chondromalacia to a greater degree than patellar dysplasias or secondary osseous changes. This variant, which could not be detected by plain roentgenography, must be considered as a pre-arthrotic deformity on account of the high point-shaped pressure load on the ridge. The findings were fully confirmed by macroscopic examination of the postmortem material.
本研究基于对250例髌股关节造影（菲卡特术语中的“造影轨迹”）的评估，这些造影是因临床怀疑髌骨软骨病而进行的，其中30例可在术中得到验证，同时也基于使用冶金中所用蚀刻膏对20具尸体膝关节进行的检查。46%的关节造影显示出一种嵴状软骨增厚，其在骨结构中未预先形成模型，将内侧小面分为正中旁段和边缘段，与软骨软化的相关性大于髌骨发育异常或继发性骨改变。这种普通X线摄影无法检测到的变异，由于嵴上存在高点状压力负荷，必须被视为关节前畸形。尸检材料的宏观检查完全证实了这些发现。
