### Patient: Doctor, I fell down the stairs and hurt my knee. It's swollen and painful. I think I may have fractured my patella. 
### Doctor: Based on your symptoms, I would recommend a radiographic imaging procedure. We will need to do a plain x-ray to confirm if you have a fracture of the patella. We will also need to apply a splint to immobilize your knee and prescribe physical therapy exercises to aid in your recovery. If required, we may also do a scan ct to further examine the extent of the injury. In addition, we will also provide wound care management to prevent any infections. Do note that a head ct is not necessary for this injury.
