Knee pain is characterized by a feeling of pain in the knee joint caused by injury or overuse. The knee joint consists of small bone structures, the kneecap, supporting ligaments and cartilage of the knee. This joint bears the full weight of the body, which makes it very vulnerable to injury.

Causes of knee pain

Knee pain is usually caused by injuries to the knee such as exposure to a direct force on the knee, abnormal twisting of the knee or falling on your knees. Some causes of knee pain are -

• Knee strains and sprains - Overworking the knee joints can damage the tissues of the knee joint resulting in knee sprains and strains
• Osteoarthritis - it is condition where the protective cartilage around the kneecap is damaged, resulting in knee pain
• Bursitis - Excessive movement of the knee or kneeling down for extended periods can irritate the bursa (a fluid sac below the skin above the knee joint) that causes swelling and pain, thereby giving rise to this condition
• Gout - This condition is characterized by the accumulation of uric acid in crystal form around the knee joint, causing inflammation and pain
• Tendon disorders - Tendons connect the muscles to the bones, and overworking the knee can cause the tendons around
  the knee to become sore and painful
• Kneecap dislocation - Injuries may cause the kneecap to shift out of its position, this causes swelling and pain in the knee joint

Symptoms of knee pain

Severe knee pain can restrict movements such as walking or standing. The symptoms vary according to the extent of the damage suffered by the knee.
