Knee joint pain is a common symptom of knee arthritis and belongs to aseptic osteoarthritis. The main pathological change is inflammation caused by poor tissue microcirculation. Inflammation process is that cell metabolites can not be well absorbed, which in turn stimulates tissues and leads to inflammation. After a long time, there will be some tissue degeneration, including bone hyperplasia, soft tissue hyperplasia or cartilage wear. Due to the occurrence of hyperplasia, there will be opportunities to compress the surrounding nerves and blood vessels, leading to blood flow disorders and pain.

In the case of joint pain, you can take the local application of finding relatives and raising children, just outside the painful part of the knee, and then pay attention to some exercise at ordinary times:

1, supine with straight legs up. Supine straight leg lifting is very helpful for the maintenance of knee joint. The specific method is: lie on your back, straighten one leg, lift it about 60 degrees, and hold it for 1 ~ 3 minutes at the beginning. After practicing for a period of time, you can also practice lifting a pillow with your feet to increase your strength, 2 ~ 3 times a day.

2. Ride a bike. However, attention should be paid to adjusting the height of the car seat. It is advisable to sit on the car seat with two pedals, and the legs can be straight or slightly bent. Too high, too low or pedaling hard when riding uphill will have adverse effects on the knee joint.

3. Take a walk. Walking is also one of the good maintenance methods. Walking can exercise the waist and legs, enhance the tension and elasticity of the muscles and ligaments of the waist and knee, and make the joints of the lower limbs more flexible, which is a way to prevent premature stiffness of the limbs.
