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).

When you straighten your knee, a grinding sensation may be felt below the kneecap. Pressing the kneecap when the knee is straight may be painful.

X-rays are usually normal, although a special x-ray view of the kneecap may show signs of arthritis or tilting.

1.Magnetic resonance imaging (MRI):Using radio waves and a strong magnetic field, MRIs produce very detailed images of bones and soft tissues. But MRIs are much more expensive than X-rays or CT scans.

2.Computerized tomography (CT scan):CT scans combine X-ray images taken from many different angles to create cross-sectional images of internal structures. CT scans can visualize both bone and soft tissues, but the procedure delivers a much higher dose of radiation than do plain X-rays.

3.X-rays:A small amount of radiation passes through your body in the process of creating X-ray images. This technique visualizes bone well, but is less effective at viewing soft tissues.

The diagnosis of Chondromalacia Patella is mainly medical examinations, X-ray examination and radionuclide release check.

The patella grinding test pressure:Check to make patella femoral condyle and its relative co-extruded between the articular surface grinding or sliding up and down about, there is a sense of rough friction, friction noise and the pain does not apply; or check who single-handedly force the patella into one side of the thumb the other hand, push the edge of the back of the patella can cause pain. Effusion of the section, the floating patella can test positive.

One leg squat test: Single discreet sick, and gradually drop to 90 ° ~ 135 ° when pain, weak, after the single leg squat should not stand up.

X-ray examination: According to the knee is, lateral and patellar tangential X-ray film, no abnormalities seen in early and late cartilage can most wear and tear, patella femoral condyle with the gap narrowing, the patella and femoral condyle edge Hyperosteogeny have to.

Radionuclide bone imaging examination, the lateral patella showed the limitations of radioactive concentration.
