Knee Cartilage Lesions

  • Cartilage defect. A cartilage defect can occur acutely when standing, turning, or pivoting during sport or as a result of trauma. This is usually followed by swelling of the knee and is aggravated by walking, standing, rising from a chair, or going up or down stairs. ┬áSometimes a cartilage fragment can’t come loose from the adjacent bone, which is most recognizable by a longer period of slight pain in the knee aggravated by an acute moment with locking and mechanical symptoms

A cartilage defect is characterized by:

  • Pain and tenderness. A cartilage defect causes diffuse pain in the whole knee, sometimes more specific in the damaged compartment, or pain more deeply located in the back of the knee
  • Locking. If a loose piece of cartilage gets stuck between the moving parts of the knee, the knee can be locked. This is a very acute phenomenon that occurs and disappears spontaneously. ┬áSometimes a loose piece can be felt floating around
  • Swelling. This occurs because damage to the articulating surface causes the knee to swell, which usually is related to the amount of loading
