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.

迹象 & 症状

The most common symptom of patellofemoral pain syndrome is a dull ache under the kneecap while walking down stairs, squatting or getting up after sitting for a long time. 除了, 你的膝盖弯曲时可能会卡住, and you may experience a painful grating or creaking sensation.

Although many physically active people notice 症状 when starting a new activity or increasing their level of intensity, people who don’t exercise may also experience patellofemoral pain simply doing their daily activities.

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. You also may be asked about any other conditions you have, 比如糖尿病和过敏, 以及你目前是否在服用任何药物.

Should your doctor require a closer look, the following tests may be ordered:

x射线. Taking images from different angles can show when your kneecap goes off track.
磁共振成像(MRI). This valuable tool can reveal whether your pain is due to bone, cartilage or muscle problems.

治疗

The vast majority of people – as high as 90 percent – recover fully from patellofemoral pain and are able to resume their previous activities. Most active people respond to nonsurgical treatments. Surgery is considered only in rare cases when patients haven't experienced relief from rest, 使用支架和物理治疗.

如果你的膝盖骨不正常, your doctor will prescribe a well-supervised physical therapy program lasting six weeks to six months, 取决于不对齐的程度. You'll learn specific movements for strengthening the knee, 腿筋和小腿肌肉, 并防止问题再次发生, you'll probably need to continue doing these exercises for life.
