Knee joint redness, swelling, heat and pain

On TV, we often see athletes retiring due to injuries. This may seem strange to us ordinary people. Why do athletes retire due to injuries? Don’t they usually provide protection? Or is it because they use it improperly? In fact, the actual situation is this: athletes need to put in a hundred times more effort than ordinary people to practice or complete an action. During this process, joints and muscles throughout the body need to bear huge exercise loads. Over time, sports injuries occur. This is not limited to any one type of athlete, but is common among athletes. We also commonly experience joint or muscle soreness due to fatigue. What causes redness, swelling, heat and pain in the knee joint?

Knee pain is perhaps one of the most difficult conditions of all joints to diagnose and treat. It not only involves various lesions within the joints, but is also often caused by various factors outside the joints. Therefore, it is particularly important to have a preliminary identification of the causes of joint pain. Here are six major causes of knee pain and how to deal with them!

1. Chronic synovitis

Symptoms include chronic pain and swelling in the knee joint. Arthroscopy may reveal synovial effusion, synovial hyperplasia, hypertrophy and even inflammation.

Recommendations: 1. Rest and avoid strenuous exercise; 2. Avoid excessive cold or heat stimulation; 3. Take oral amino acid glucose drugs, and oral analgesics can be taken if the pain is severe; 4. Acupuncture and physical therapy.

2. Osteoarthritis

There is obvious joint pain when standing up after sitting or squatting for a long time, or when going up and down stairs, which will be relieved after rest. In addition to joint swelling and pain and limited movement, X-rays may also reveal narrowing of the joint space, bone spur growth and joint deformation.

Recommendations: 1. Avoid abrasive activities such as cycling and climbing stairs; 2. Take oral cartilage nutrition drugs, such as amino acid glucose; 3. Acupuncture treatment; 4. If the above methods cannot provide relief, undergo knee replacement surgery;

3. Loose bodies in the knee joint

When walking, the legs suddenly feel weak and the joints feel stuck. The legs cannot be moved and can be maintained in one position. Gently lift the legs and swing them, and the stuck feeling disappears. This is because the articular cartilage wears off and forms loose bodies that are stuck in the joint space.

Recommendation: A small amount of loose bodies do not need to be treated; if the knee joint is frequently stuck, arthroscopic surgery is required to remove the loose bodies.

4. Bursitis

There is a history of trauma or cold, which manifests as pain above the kneecap or on the inner side of the tibia. There is a place on the inside of the knee joint, medically known as the "goose foot". Three tendons converge here like a goose foot, hence the name. There is a lubricated cystic structure hidden under the tendon. If there is trauma or cold, this area is prone to inflammation and pain.
