Patella Fracture
Medical term: Patellar Fracture
Overview
A patella fracture is a break in the kneecap, the small, flat bone that sits at the front of the knee and protects the joint. The patella plays a critical role in the knee’s extensor mechanism, acting as a fulcrum to increase the leverage of the quadriceps muscle when straightening the leg. Patella fractures most commonly result from a direct blow to the knee, such as a fall onto a hard surface or striking the dashboard in a motor vehicle accident.
The treatment approach depends on whether the fracture is displaced and whether the extensor mechanism of the knee is intact. Non-displaced fractures may be managed with immobilization, while displaced fractures typically require surgical fixation to restore the joint surface and the ability to straighten the knee. Our San Diego trauma surgeons carefully evaluate each patella fracture to determine the most effective treatment strategy and guide patients through a structured rehabilitation program.
