Studying one hundred cases of simple gonarthrosis we found only one supra trochlear femoral erosion (STFE). Such a lesion was discovered in 14 cases among 150 chondrocalcinosis with arthrosic lesions. The cases involving STFE trend to a commun marked chondro-osteolytic evolution. The caracteristic patella sizes show clearly that STFE is not in relation with en anomaly of patella (patella alta...). The upper osteophyte of the patella presents only a minor importance in the formation of STFE. This STFE formation begins probably with a progressive chondro-osteolysis of patella and trochlea. Then, appears a progressive nipping between the upper point of patella and the supra trochlear femoral bone.
在研究100例单纯性膝关节病时，我们仅发现1例股骨滑车上方侵蚀（STFE）。在150例伴有关节病变的软骨钙质沉着症病例中，有14例发现了这种病变。涉及STFE的病例倾向于共同的明显软骨骨质溶解演变。特征性的髌骨大小清楚地表明，STFE与髌骨异常（高位髌骨等）无关。髌骨上骨赘在STFE形成中仅起次要作用。这种STFE的形成可能始于髌骨和滑车的渐进性软骨骨质溶解。然后，在髌骨上点和股骨滑车上方骨之间出现渐进性挤压。
