Chondromalacia patellae

• Knee tenderness
• Knee pain in the front of the knee that worsens after sitting for prolonged time
• Knee pain that worsens with using stairs or getting out of a chair
• A grating or grinding sensation when the knee is extended

The doctor will perform a physical examination. The knee may be tender and mildly swollen, and the kneecap may not be perfectly lined up with the femur (thigh bone) underneath.

When the knee is extended from the flexed (bent) position, a grinding sensation may be felt below the kneecap. With the knee extended (straight), pressing the kneecap against the femur may be painful.

X-rays are usually normal, although a special x-ray view of the kneecap may show arthritic changes.
