The etiology of patellar cartilage lesions in recurrent patellar dislocation has been poorly understood.
The pathology of cartilage lesions of the patella accompanied by recurrent patellar dislocation can be analyzed.
Series of case reports.
In 70 knees from 57 patients with recurrent patellar dislocation, the cartilage lesions of the patella were examined using arthroscopy and/or macroscopic observation. The average age of the patients was 22 years (range, 13 to 40 years). Lesions that involved only softening were not included.
Sixty-seven knees (96%) had articular cartilage lesions of the patella, and only 3 knees had no change. Fissuring was observed in 53 knees (76%). The most common site of fissuring was on the central dome. There were basically two types of fissuring: multiple longitudinal fissuring and marginal/radial fissuring. Fibrillation and/or erosion were observed in 54 knees (77%). Of these, 40 knees had fissuring and 14 did not have fissuring. The main site of fibrillation and/or erosion was the medial facet.

复发性髌骨脱位中髌骨软骨损伤的病因一直未被充分了解。
可以分析伴有复发性髌骨脱位的髌骨软骨损伤的病理情况。
系列病例报告。
对57例复发性髌骨脱位患者的70个膝关节进行了研究，采用关节镜检查和/或肉眼观察来检查髌骨软骨损伤情况。患者的平均年龄为22岁（范围为13至40岁）。仅涉及软化的损伤未纳入研究。
67个膝关节（96%）存在髌骨关节软骨损伤，只有3个膝关节无变化。53个膝关节（76%）观察到有裂缝。裂缝最常见的部位是中央穹顶。裂缝基本上有两种类型：多条纵向裂缝和边缘/放射状裂缝。54个膝关节（77%）观察到有纤维化和/或侵蚀。其中，40个膝关节有裂缝，14个膝关节没有裂缝。纤维化和/或侵蚀的主要部位是内侧小面。
复发性髌骨脱位病例中髌骨软骨损伤非常常见。裂缝主要出现在中央穹顶，纤维化和/或侵蚀主要出现在内侧小面。
