Understanding Patella Fracture: A Comprehensive Guide

A patella fracture can bring even the simplest daily tasks to a screeching halt. In this article, we’ll explain what a patellar fracture is, how serious it can be, what causes it, symptoms to watch for, diagnostic steps, treatment options, and the path to recovery.

What is a Patellar Fracture?

A fracture of the patella is a break in the kneecap (patella). The fracture could be a displaced fracture, comminuted fracture, transverse fracture, or open fracture. Because the patella is integral to the knee joint, even a small bone injury can disrupt your ability to bear weight or extend your leg. The inability to do a straight leg raise is a hallmark sign of a patella fracture.

How Serious is a Patellar Fracture?

Patellar fractures range from stable fractures to highly complicated fractures with shattered bone pieces. A simple patellar fracture typically involves minimal displacement and doesn’t compromise the articular cartilage. 

However, with most patellar fractures, the bone shatters, creating a comminuted fracture with fragments in the joint space, which becomes a serious injury requiring swift medical attention. Displaced ends of a fractured bone may impact the smooth joint surface, increasing the risk of arthritis. If the bone breaks so that the bone fragments stick out through the skin, there is an increased risk of infection.

What Causes a Patellar Fracture?

Patellar fractures are often due to direct trauma, such as a fall onto the front of the knee or a blow during contact sports. It is also possible for the patella to be fractured indirectly, with a sudden contraction of the quadriceps muscle, causing the patellar tendon to pull sharply on the kneecap and break it.

What Are the Symptoms of a Patellar Fracture?

Common signs of a patellar fracture include the following:

  • Painful swelling and bruising
  • Inability to perform a straight leg raise, due to a loose patellar tendon or disrupted leg muscles
  • Pain when trying to bear weight on the leg

How is a Patellar Fracture Diagnosed?

Orthopaedic surgeons evaluate the injury using:

  1. Physical examination: An assessment of the swelling, palpation for broken pieces, and determining if the kneecap moves abnormally.
  2. X-rays: These can help identify whether it’s a transverse fracture, comminuted fracture, or displaced fracture, and to see if the remaining patellar bone is stable.
  3. MRI/CT scan: If the joint space is affected or articular cartilage is damaged, an MRI or CT scan can assess surrounding soft tissues, the patellar tendon, and joint integrity.

How is a Patellar Fracture Treated?

Treating fractures of the patella depends on the type of fracture.

Non-Surgical Treatment

For a stable fracture where bone ends are closely aligned, a knee brace or cast may be used. This lets the fracture heal while the leg muscles and thigh muscles rest. During this time, gentle physical therapy can begin to strengthen supporting muscles.

Surgical Treatment

When more complicated fractures occur, especially those involving a displaced fracture with fragments, surgical treatment may be needed. The surgical procedure involves the following:

  • Tension band wiring to hold the pieces of bone in place
  • Screws and plates to fixate the kneecap
  • Removal of loose patellar tendon, bone fragments, or fragments that disrupt the joint surface
  • Repair of an open fracture, where both the wound and bone are exposed
 

Orthopaedic surgeons aim to restore the normally smooth joint surface and preserve the articular cartilage.

Recovery

Recovery from patellar fractures can take several months. After initial immobilization, you’ll work on:

  1. Regaining range of motion in the knee joint as the bone heals
  2. Rebuilding strength in the leg muscles and hip stabilizers
  3. Slowly progressing to bear weight as your injury heals
  4. Restoring function. Achieving a straight leg raise is often a key milestone

Your care plan will be tailored depending on your fracture type.
