What are the symptoms of a knee injury?

Symptoms of knee injury include pain, limitation of movement, the presence of cracking or popping sounds, instability of the knee joint, and swelling, redness, or warmth of the skin. Symptoms may be mild or severe and depend to a great degree upon both the extent and severity of the injury.

  • Pain, whether at rest or during specific movements, that may be described as dull, sharp, burning, stabbing or aching
  • Popping, snapping or cracking sounds when the joint is moved
