Causes of Knee Pain

Knee pain usually results from overuse, poor form during physical activity, not warming up or cooling down before exercise, or inadequate stretching. Simple causes of knee pain often clear up on their own with self-care. Being overweight can put you at greater risk for knee problems. The following reasons are usually associated with knee pain:

• Bursitis: It occurs due to inflammation from repeated pressure on the knee (like kneeling for long periods of time, overuse, or injury.)
• Torn or ruptured ligaments or torn cartilage (a meniscus tear): They can cause severe pain and instability of the knee pain.
• Strain or sprain: It occurs due to minor injuries to the ligaments caused by sudden or unnatural twisting.
• Dislocation of the kneecap
• Infection in the joint
• Knee injuries: It can cause bleeding in your knee, which worsens the pain.
• Hip disorders: They can result in pain that is felt in the knee. For example, iliotibial band syndrome is injury to the thick band that runs from your hip to the outside of your knee.
• Ligament Injury: A ligament injury to the knee is usually painful at rest and may be swollen and warm. The pain is usually worsened by bending on the knee or walking. The severity of the injury can vary from mild to severe.
• Tendinitis: Tendinitis of the knee occurs in the front of the knee below the kneecap at the patellar tendon, or in the back of the knee at the popliteal tendon. It is an inflammation of the tendon, which is often produced by a strain event, such as jumping.
• Gout: Gout is due to increased level of uric acid in the blood.
• Fractures: With severe knee trauma, such as motor vehicle accidents and impact traumas, bone breakage of any of the three bones of the knee can occur.
• Meniscus Tear: Patient with a meniscal tear may have a rapid onset of a popping sensation with a certain activity or movement of the knee.Occasionally, it is associated with swelling and warmth in the knee.
