Knee bending pain after a long period of immobilization may be caused by knee trauma, knee wear and tear, etc. It can be treated by physical therapy, medication, surgery and so on.
1. Knee trauma: the external force may lead to inflammatory reactions such as congestion in the local soft tissues of the knee joint, thus leading to the phenomenon. In order to reduce pain, infrared laser, medium frequency electrical stimulation and other physical therapy can be carried out to promote blood circulation and accelerate the metabolism of inflammation. Anti-inflammatory drugs such as ibuprofen can also be taken. You can also perform stretching exercises under the guidance of a doctor to relieve pain.
2. Knee wear and tear: Repeated friction of the knee joint may lead to wear and tear and degeneration of the knee joint, which will enhance the friction of the joint surfaces after bending, thus generating pain. Sodium vitrate injection under ultrasound can be performed to alleviate the symptoms. Physical therapy such as microwave therapy and magnetic therapy may also be performed to improve blood flow and reduce inflammation. If conservative treatment is not effective, surgery is required.
When the knee bends and hurts after a long period of immobilization, it is necessary to go to the hospital in a timely manner to clarify the cause of the disease, and to target medical treatment.
