X-Ray Library Patella
This section is intended to give you a little more detail about what your particular problem or injury looks like radiographically (by X-ray images).
The images on this page represent normal patellar (knee cap) anatomy as well as X-rays of knees with chondromalacia (thin and softening cartilage) and Degenerative Joint Disease (DJD). Some images show what the knee cap looks like if it 'pops' out of place (which is called subluxating/slipping or dislocating). There are a few images which demonstrate how some of these problems can be fixed.
