Why do my knees hurt when I squat? Is knee pain a sign of knee damage?

Many people experience slight popping sounds when moving their knees, which is fine if there is no pain. If there is pain, you should prepare for treatment.

Why do my knees hurt when I squat?

If your knee hurts when you squat and stand up, and also hurts when you go up and down stairs, but you don't feel any pain when you walk on a flat road, you should consider a typical disease - popliteal muscle injury.

There is obvious pain in the popliteal muscle under the popliteal fossa behind the knee joint. The pain in the affected leg is much more severe than that in the healthy leg. This is the smallest knee flexor muscle in the large joint of the knee. A large joint with a small muscle is very easy to be injured. The tibial nerve is close to the popliteal muscle. Once the popliteal muscle is tense and painful, stimulation of the tibial nerve will radiate pain to the front of the knee joint.

When going up and down stairs or squatting, the popliteal muscle contracts further and the stimulation becomes more intense, and the symptoms are particularly obvious. You can try massaging with a strength that the pain can be tolerated, once a day, for about 7 minutes each time, from shallow to deep. Once the pain disappears, the symptoms will disappear as well.

Knee pain means the knee is broken?

There are many reasons for knee pain, and it is not necessarily a problem with the knee.

1. Pain when going up and down stairs

Knee pain when going up and down stairs, difficulty squatting, no pain when walking on flat ground, no knee joint disease found in CT or MRI at the hospital, pain in the popliteal muscle below the popliteal fossa upon palpation, radiating pain induced by tibial nerve entrapment due to popliteal muscle injury should be considered.

2. Pain on the outside of the knee

This depends on whether there is any injury to the lateral meniscus, injury to the lateral collateral ligament, pain in the vastus lateralis muscle attachment point at the knee joint, or pain caused by tension in the iliotibial band and friction with the lateral femoral condyle.

3. Pain on the inner side of the knee

This requires checking for medial meniscus injury, medial collateral ligament injury, anserine bursitis, and pain at the attachment point below the vastus medialis muscle, all of which can cause pain on the inside of the knee.

4. Knee swelling

Many people have swollen knee joints with fluid accumulation, which may be synovitis. However, remember that sodium hyaluronate is just a lubricant. Do not inject it frequently in a short period of time. Too much is as bad as too little.

Why does knee pain occur?

1. History of trauma: Injury to the meniscus, cruciate ligament, ligaments and bursa around the knee joint causes decreased knee joint function and stability, leading to pain.

2. Improper exercise: Unreasonable exercise, not doing proper warm-up before exercise, not doing proper stretching and relaxation after exercise, or unreasonable exercise arrangement, excessive exercise, or excessive exercise can also cause joint pain.

3. Lumbar or hip diseases: Lumbar lesions may cause lower limb pain, muscle atrophy, coldness, numbness, fear of cold, pain and other symptoms. Hip joint lesions, such as femoral head necrosis, can also cause knee pain. Excessive weight Excessive weight causes excessive pressure on the knee joint, causing pain.

4. Aging of the knee joint: After the human body is over 30 years old, the knee joint will undergo degenerative changes. The strength, elasticity, and toughness of the surrounding muscles and ligaments will decrease, the synovial fluid secretion in the joint cavity will decrease, and long-term friction between the joint bone surfaces will cause bone wear and osteoarthritis. Osteoarthritis is more common in middle-aged and elderly people, mostly women.

5. Cold: Cold can cause muscle and blood vessel contraction, causing joint pain. Long-term exposure to cold or dampness in the knee joint is the main cause of knee pain.

6. Abnormal force line: Incorrect force line of the knee joint, such as O-shaped legs, X-shaped legs, or bad walking habits, will cause the knee joint to be in an abnormal stress state for a long time, causing chronic injury to the knee joint and causing knee pain.

7. Immune diseases: Rheumatism, rheumatoid arthritis, ankylosing spondylitis, lupus erythematosus and other immune diseases can cause knee joint lesions.

8. Metabolic diseases: Metabolic diseases such as gout can also cause knee pain, and with the improvement of living conditions, the incidence rate has a clear upward trend.
