Patellar (Kneecap) Fracture Diagnosis

Orthopedic Surgery

How is a patellar fracture diagnosed?

After discussing your symptoms and medical history, your doctor will examine your knee. The edges of the fracture can often be felt through the skin, particularly if the fracture is displaced.

During the exam, your doctor will check for hemarthrosis. In this condition, blood from the fractured bone ends collects inside the joint space, causing painful swelling. If you have a large amount of blood in your knee, your doctor may drain it to help relieve your pain. Your doctor will also order x-rays to help diagnose your fracture.
