The patella, also known as the kneecap, is the largest sesamoid bone in our body. It plays a crucial role in knee extension mechanics and provides protection against direct trauma. Patella fractures constitute about 1% of all skeletal injuries, affecting both adults and children alike. These fractures can occur due to direct hits, like falling on a bent knee, or indirect forces, such as a sudden powerful contraction of the thigh muscles.

If you experience sudden knee swelling and pain after an injury, you might have a patella fracture. Medical professionals will assess your knee's extensor mechanism and look for open fractures. Radiographs, which include various views of the knee, are typically used to diagnose this condition. In some cases, ultrasound might be used to further evaluate the knee and confirm a fracture.

The treatment for patella fractures depends on the severity and type of fracture. Displaced fractures generally require surgical intervention, while non-displaced ones can often be managed with immobilization. For non-surgical cases, a knee brace or cast is used to keep the knee in place and allow it to heal over several weeks. Rehabilitation exercises are crucial to regain strength and mobility after the initial treatment phase.

Understanding the causes and treatment of patella fractures can help you manage this condition effectively.
