Patella Fracture (Broken Knee Cap)

We Can Help You

A patella fracture, or a broken kneecap, is a serious injury that occurs when the small, round bone covering the knee joint, known as the patella, cracks or breaks. The patella plays a crucial role in knee mechanics, acting as a shield for the knee joint and as a fulcrum to increase the leverage of the thigh muscles that extend the leg. Due to its position at the front of the knee, the patella is vulnerable to injury from direct blows or falls onto the knee, as well as from sudden contractions of the quadriceps muscle, which can lead to a fracture if the force is too great.

Symptoms of a patella fracture include intense pain in the knee, swelling, bruising, and difficulty walking or straightening the leg. In some cases, the knee may also appear deformed due to displacement of the broken bone pieces.

Diagnosis of a patella fracture typically involves a physical examination, followed by imaging tests such as X-rays or a CT scan to determine the extent of the fracture and whether the bone pieces are displaced.

The Road Back

Treatment for a patella fracture depends on the type and severity of the break. Non-displaced fractures, where the bone pieces remain aligned, may be treated conservatively with immobilization in a cast or brace, allowing the bone to heal naturally. However, displaced fractures often require surgical intervention to realign and fix the bone pieces using pins, screws, or wires. Rehabilitation, including physical therapy, is essential after the initial healing process to restore knee strength, flexibility, and function.
