Medical Library: Knee – Fractures
A broken kneecap or patella fracture is an injury to the kneecap, which is one of three bones that make up the knee joint. The patella is coated with cartilage on its undersurface and helps provide strength when straightening the knee joint.
Fractures of this type occur most often from a fall directly onto the kneecap. One of the critical factors in determining treatment is a thorough examination to determine if the patient can perform a straight leg raise.
Knee swelling is one of the common symptoms of a patella fracture. Using a knee brace to immobilize the knee will also help minimize pain and discomfort.
