6Diagnosis
To diagnose a patellar fracture, a doctor first needs to know about your medical history and symptoms. After that, a physical exam is performed to check for specific signs. The edges of a fracture would be felt through the skin, especially when it is displaced. He or she might also look for hemarthrosis, which occurs when blood from the ends of the fractured bones collects in the joint and causes swelling. An X-ray is helpful to learn more about the severity and type of patellar fracture. This imaging technique provides detailed pictures of the bones. [6]
