Where does my pain come from? Can I still use my knee? How bad is it?

What Causes Knee Pain

Knee pain is very common, especially on athletes and elderly. But what causes knee pain varies from one person to another. Some are due to injuries, while the others are caused by diseases and health conditions.


What Causes Knee Pain – Common Injuries

For some people, especially those who do sports, what causes knee pain is generally a trauma-borne injury.
Here are the common injuries that cause knee pain.

  • Ligament injury
    What causes knee pain?A torn knee ligament can cause knee pain. The resulting pain is immediate; however, it is hard to pinpoint its exact location.

    The pain caused by torn ligament usually worsened as the patient bends his knee, walks, or puts weight on it.

    The severity of the case may vary from insignificant (normally caused by minor tearing or stretching of the ligament fibers) to severe (ligament fibers are torn completely).

    In one traumatic event, a person can experience more than one torn ligament in the knee area.

  • Meniscus tears
    A torn meniscus is caused by rotating the knee in a sharp, rapid motion. Athletes of sports requiring such body movements are prone to this injury. A torn meniscus is often determined by the popping and unstable sensation when the knee is moved. Moreover, it can be associated with warmth and swelling around the area.
  • Tendinitis of the knee
    Sometimes, what causes knee pain is the tendinitis of the knee. Often produced by jumping and other strain events, tendinitis is basically a tendon inflammation. Typically, a knee tendinitis is treated with R.I.C.E. or Rest, Ice, Compress, and Elevation, but a doctor can also prescribe anti-inflammatory drugs when needed.
  • Fracture
    When a person has impact trauma, such as a vehicular accident, bone breakage or fracture in the knee can happen. Knee bone fractures are usually repairable by casts, braces, or other means of support, but sometimes the fracture is so severe a surgical repair is required.

Diseases and Conditions That Cause Knee Pain

Sometimes, a condition or disease causes knee pain, instead of injury. The most common diseases and health conditions that cause pain of the knee include:


  • Arthritis, which includes rheumatoid arthritis, gout, and osteoarthritis
  • Baker’s Cyst
  • Bone and joint infection
  • Tumors like giant cell tumors and synovial sarcomas
  • Pellegrini-Stieda syndrome
  • Chondromalacia
  • Bursitis of the knee

Determining what causes knee pain is vital to proper knee pain diagnosis and treatment. Consulting a doctor is the best move to do in order to know the exact cause of knee pain.
