通过观察髌骨软化症患者屈膝疼痛时股内肌和股外肌的肌电活动、膝关节Ｘ光轴位片以及伸膝等动力量测定，拟在探讨髌骨软化症患者髌骨疼痛、髌骨位置及股内肌机能状况的相互关系。结果表明：髌骨软化症患者股内肌张力相对较高，导致髌骨向内偏移、屈膝时疼痛。而点揉血海穴后股内肌张力下降，髌骨位置外移并恢复正常，屈膝疼痛缓解。因此认为髌骨软化患者屈膝疼痛与骸骨向内偏移有关。建议在运动训练中注意掌握正确的动作结构，屈膝旋转时应保持大小腿和足在同一平面的同步活动，使髌骨保持正常的活动位置
By observing the myoelectric activity of the intramuscular and extra-occipital muscles, knee X-ray and extension extensor kinematics in the patients with chondromalacia patellae knee pain, the patella pain, patellar position and pterygium Internal Muscle Function Status Interrelationship. The results showed that the tension of intracranial muscle in patients with chondromalacia patellae was relatively high, which led to the shift of the patella inwardly and the pain of knee flexion. The point of intracranial muscle acupuncture points to reduce the tension, patellar shift and return to normal position, knee pain relief. Therefore, patients with patella flexion and knee flexion and skeletal inward migration. It is recommended to pay attention to exercise in the training of the correct structure of the movement, knee rotation should keep the size legs and feet in the same plane synchronized activities, the patella to maintain normal activity position
