The frequency of recurrent dislocation of the patella is increased by the young age of onset, the presence of patella alta and permanent subluxation of the patella. The natural history of the patellar syndrome appears to be fairly favourable in everyday activities, but discomfort is often marked in the intermediate term in sports activities. Isolated femoropatellar osteoarthritis rarely causes major functional impairment of gait. Medial or lateral femorotibial osteoarthritis occurs secondarily. Painful cases often present with subchondral anomalies of the lateral patellar facet, lateral tibial osteophytosis and patella alta.
髌骨复发性脱位的发生率因发病年龄较轻、高位髌骨的存在以及髌骨永久性半脱位而增加。髌股综合征的自然病程在日常活动中似乎相当良好，但在中期的体育活动中常常会出现明显不适。单纯的髌股关节炎很少导致步态的严重功能障碍。股胫内侧或外侧关节炎为继发性。疼痛病例常伴有髌外侧小关节面软骨下异常、胫骨外侧骨赘形成及高位髌骨。
