Understanding Knee Pain
Common Causes of Knee Pain
Knee pain can stem from various sources, including injuries, mechanical issues, types of arthritis, and other medical problems. It can start suddenly or develop gradually from mild discomfort to severe pain over time.
- Injuries: Common knee injuries include ACL injury and torn meniscus. These injuries can result from sports, accidents, or sudden movements.
- Mechanical Problems: Issues like dislocated kneecap or hip problems can lead to knee pain.
- Arthritis: Several types of arthritis, such as osteoarthritis, rheumatoid arthritis, and gout, can cause knee pain.
- Medical Conditions: Obesity, aging, and wear and tear are other contributing factors to knee pain.
Ignoring long-term knee pain and leaving injuries untreated can lead to chronic pain and conditions like osteoarthritis, tendinitis, or bursitis [5].
Symptoms of Knee Pain
The symptoms associated with knee pain can vary depending on the cause and severity of the problem. Some common symptoms include:
- Swelling and Stiffness: These are often the initial signs of knee issues.
- Redness and Warmth: These symptoms indicate inflammation or possible infection.
- Weakness or Instability: Feeling as though your knee is giving way or can't support your weight.
- Popping or Crunching Noises: These sounds can accompany movements of the knee joint [2].
| Symptom |
Description |
| Swelling |
Increased fluid in the knee joint, often accompanied by stiffness. |
| Redness and Warmth |
