What is a Kneecap Fracture?

What Causes a Kneecap Fracture?

Hitting a dashboard, a direct blow from a hard object or falling onto the knee can break the patella. A sudden strong pull from the quadriceps can rarely avulse bone. Separated fragments disrupt active knee extension.

Symptoms

• Marked pain and tenderness at the front of the knee
• Rapid swelling or blood around the patella
• Inability to lift the leg while keeping the knee straight
• Difficulty climbing stairs or rising from a chair

Frequently Asked Questions

How is a kneecap fracture treated?

A brace and controlled movement may be enough when fragments remain aligned and active straightening is preserved. Separated fragments or a disrupted extensor mechanism require surgical fixation, followed by gradual knee rehabilitation.
