Knee pain is mainly treated according to different causes. First, if the patient is osteoarthritis, we can use painkillers at an early stage and tell the patient to avoid strenuous activities. We can take glucosamine capsules orally. If the pain continues to worsen, we can treat it with sodium hyaluronate in the joint cavity.

If the patient's pain is severe and affects walking, artificial knee replacement can be performed.

Second, if the patient has knee pain caused by rheumatism, we can treat rheumatism.

Third, if the patient suffers from pain caused by osteoporosis, anti-osteoporosis treatments such as calcium supplementation, vitamin D3 and sun exposure can be added.

Fourthly, if the patient has severe pain at night, tumors, especially primary tumors and secondary tumors, should not be ruled out. It is recommended to do magnetic resonance imaging or CT examination to check the cause and further treatment.
