The knee is considered as the largest joint in the body of human. Injury in this area can trigger severe knee pain that affects productivity and daily activities.
The upper and lower bones of the knee are divided into 2 discs. The upper and lower bones are connected by ligaments, tendons, and muscles. The bone surface inside the knee joint is covered with a layer of cartilage that reduces shock and protects the surface when moving. Thanks to this special structure, the movement does not cause pain. However, you are still at risk of developing knee pain if they are injured or abrasive during daily activities.
The sudden injury
Direct injuries to the knee, such as falling or bending over, are a common cause of knee pain. You will feel pain, swelling and heat when you are injured. Wounds can destroy nerves and blood vessels. The knees and calves become weak, swollen and cyanotic. The following are common knee injuries:
- Sprains, dislocations or damage to ligaments and tendons
- Fractures of the patella, the lower part of the femur, the upper part of the tibia or fibula
- Patella joints dislocations
- Knee dislocations.
Injury due to overexertion
Overexertion or putting too much pressure on the knee can cause injury. Daily activities such as going up and down, cycling, jumping or walking can put pressure on the joints and surrounding tissues, leading to irritation and inflammation. Common injuries in this case include:
- Wear and tear of the knee joint (cartilage)
- Ligament wear conditions such as anterior cruciate ligament (ACL)
- Bursitis. Inflammation of the fluid sac supports cushioning and lubrication of the pillow
- Chronic tendonitis.
- Crease syndrome, which causes the tendon to thicken or fold
- Patella-thigh pain syndrome. This condition causes pain in the front of the knee due to overexertion, injury, being overweight or having problems in the patella
- Pelvic floor syndrome. This condition causes irritation and inflammation of the fibrous tissue that extends to the outside of the thigh area.
