Knee Pain

Knee pain is a common condition affecting individuals from different age groups. It not only affects movement but also impacts the quality of life of the individual. An injury or disease of the knee joint or any structure surrounding the knee can result in knee pain. A precise diagnosis of the underlying cause is important to develop an appropriate treatment plan.


The causes of knee pain can be divided into three major categories:

  • Acute injuries: fractures, broken bone, ligament injuries (torn ligament, ACL injury), meniscus injuries, or dislocations
  • Medical conditions: arthritis, infections
  • Chronic conditions: osteoarthritis, tendinitis, bursitis


The severity of pain may vary from person to person, from a minor ache to a severe and disabling pain. Some of the common symptoms and signs are:

  • Redness and swelling
  • Locking of the knee (inability to bend)
  • Inability to fully extend or straighten the knee
  • Difficulty walking due to weakness or instability
  • Difficulty walking up and down stairs

When Should You See a Doctor?

Call a doctor if you notice:

  • A fever accompanied by redness, swelling, and knee pain
  • Marked knee swelling
  • An obvious deformity in your knee or leg
  • Complete inability to bear weight or extend your knee
  • A feeling of your knee “giving out”
