Why does your knee suddenly ache? There are 8 reasons for this

Sudden knee pain is a condition that many people will experience in their lives, but what exactly causes sudden knee pain? Most people don't know much about this. In fact, there are 8 reasons for sudden knee pain. The first reason is knee joint pain caused by strain or bad posture.

1. Causes of sudden knee pain

1. Knee joint pain caused by strain and bad posture.

2. Generally, knee pain in young people is caused by injury during exercise or excessive exercise.

3. Knee pain caused by osteoarthritis.

4. Knee pain caused by rheumatoid arthritis.

5. Fat pad strain. This type of injury often occurs in people who frequently walk, climb mountains, or squat. Many times patients experience knee pain that worsens when fully extended, but joint movement is not restricted. The symptoms will be more obvious after fatigue, and most people will have similar experiences.

6. If the knee joint is slightly bent and suddenly excessively rotated inward or outward, it may cause a meniscus tear. At this time, there will be an obvious tearing feeling in the knee, joint pain and limited movement, and problems will be felt when walking with a limp.

7. If the synovium is damaged by trauma or excessive strain, a large amount of fluid will accumulate, increasing the pressure inside the joint. If it is not eliminated in time, it will easily cause joint adhesion. Most people will feel pain, swelling, and tenderness in the knee joint, and the synovium will have a frictional and astringent sound.

8. Long-term overload will cause swelling and pain in the knee joint, and sometimes there will be friction sound when moving the joint. This condition is often accompanied by deformity and pain.

1. Surgical treatment: In the late stage of osteoarthritis, when deformity or persistent pain occurs and the patient cannot take care of himself, surgical treatment can be performed.

Depending on age, occupation, and lifestyle habits, knee replacement, hip replacement, etc. can be selected.

2. Drug efficacy: Non-steroidal anti-inflammatory analgesics can relieve pain, oral administration of Chinese herbal medicines that promote blood circulation and remove blood stasis, as well as external hot compresses, fumigation, soaking, etc. can relieve symptoms and delay the course of the disease. Intra-articular injection of sodium hyaluronate utilizes its rheological properties as a supplement to viscoelastic substances.

, which lubricates the joints and protects the articular cartilage. Corticosteroids should not be injected into joints. Although they can relieve symptoms in the short term, the damage to the cartilage will increase with the number of injections, which is worth noting.

3. General treatment: pay attention to rest, protect joints, avoid excessive activity or injury. In severe cases, patients should rest in bed and use a brace to prevent deformity. Physical therapy can relieve pain.
