In cases of spontaneously occurring patellar pain, there is generally some slight damage to the nerve roots and anterior horn cells of segments L3 and L4. Divergent patellar movement can be measured roentgenologically. When the quadriceps is contracted the patella normally medialward in varus joints, and lateralward in valgus joints and when the leg position is axially correct. In peripatellar pain syndrome, however, lateral movement can be demonstrated in varus joints. Additionally, there is a tendency for the rotation of the patella to depend on the innervation disorder. The discrepancy between the muscular guidance of the patella and the performed guide bed may be one of the factors causing patellar pain. Etiologically, axial malpositions of the leg appear to be important predisposing factors and innervation disorders of the quadriceps muscle realization factors.
在自发性髌痛病例中，L3和L4节段的神经根和前角细胞通常会有一些轻微损伤。髌股关节的异常活动可以通过X线检查来测量。当股四头肌收缩时，在关节内翻时髌骨通常向内侧移动，在关节外翻且腿部轴向正确时向外侧移动。然而，在髌周疼痛综合征中，在内翻关节中可显示髌骨向外移动。此外，髌骨的旋转倾向于取决于神经支配紊乱。髌骨的肌肉引导与实际引导床之间的差异可能是导致髌痛的因素之一。从病因学上讲，腿部的轴向错位似乎是重要的易感因素，而股四头肌的神经支配紊乱是实现因素。
