A syndrome of patellofemoral dysfunction, consisting of painful popping, catching, grinding, or jumping of the patellar component, can complicate total knee replacement. From October 1983 to March 1988, eleven of 635 total knee replacements had this syndrome. On arthroscopic evaluation, the dysfunction of the patellofemoral articulation was found to be secondary to intra-articular fibrous bands. In eight patients, a transverse fibrous band prevented the patella from seating well in the sulcus of the femoral component. In four patients, the fibrous band extended from the superolateral border of the patella to the infrapatellar fat pad, tethering the patella laterally. In one patient, the fibrous band extended from the distal pole of the patella to the intracondylar notch, tethering the patella inferiorly. In all patients, the symptoms resolved after arthroscopic removal of the fibrous bands.
髌股关节功能障碍综合征，表现为髌骨部件出现疼痛性弹响、卡顿、摩擦或跳动，可使全膝关节置换术变得复杂。1983年10月至1988年3月期间，635例全膝关节置换术中，有11例出现了这种综合征。经关节镜评估发现，髌股关节的功能障碍是由关节内纤维带引起的。在8例患者中，一条横向纤维带妨碍了髌骨在股骨部件的滑车沟内良好就位。在4例患者中，纤维带从髌骨的上外侧缘延伸至髌下脂肪垫，将髌骨向外侧牵拉。在1例患者中，纤维带从髌骨的远极延伸至髁间切迹，将髌骨向下牵拉。在所有患者中，经关节镜切除纤维带后症状均得到缓解。
