髌股的 疼痛 并发症状
Overview
膝盖骨, 或髌骨, is a small triangular bone at the front of the knee that moves as the joint bends. It glides up and down along a track at the end of the thighbone (femur) and gives the front thigh muscles (quadriceps) leverage for straightening the leg. The patella also protects the joint during collisions and falls.
髌股的 pain syndrome occurs when the patella cartilage is stressed by overuse or poor alignment. 高冲击力的运动,比如足球, 篮球, 足球, tennis and running – can overtax the cartilage or aggravate existing abnormal kneecap alignment. 除了, 在凹凸不平的路面上跑步, 比如山丘或小径, or playing a sport on a different surface than usual, such as a hard tennis court rather than a grass court, 会增加髌股疼痛的可能性吗.
髌股的 pain syndrome may indicate that the protective cartilage under the kneecap is wearing down, which can eventually lead to bone loss and arthritis.

诊断
After discussing your 症状 and physical activities, your doctor will examine the knee area. 在一个快速测试中, the doctor moves your kneecap to see how well it tracks as you flex and extend your leg. 在这个简短的考试之后, your doctor most likely will know whether your discomfort is due to patellofemoral pain syndrome or another knee problem.
