A patellar fracture is a break in the patella, or kneecap, the small bone that sits at the front of your knee. Because the patella acts as a shield for your knee joint, it is vulnerable to fracture if you fall directly onto your knee or hit it against the dashboard in a vehicle collision. A patellar fracture is a serious injury that can make it difficult or even impossible to straighten your knee or walk.
Some simple patellar fractures can be treated by wearing a cast or splint until the bone heals. In most patellar fractures, however, the pieces of bone move out of place when the injury occurs. For these more complicated fractures, surgery is needed to restore and stabilize the kneecap and allow for the return of function.
Types of Patellar Fractures Stable fracture & Displaced fracture: In a displaced fracture, the broken ends of the bone are separated and do not line up correctly. The normally smooth joint surface may also be disrupted. This type of fracture often requires knee replacement surgery to put the pieces of bone back together. Comminuted fracture: In this type of fracture, the bone shatters into three or more pieces. Depending on the specific pattern of the fracture, a comminuted fracture may be either stable or unstable.
Open fracture:In an open fracture, the bone breaks in such a way that bone fragments stick out through the skin or a wound penetrates down to the bone. An open fracture often involves damage to the surrounding soft tissues and may take a longer time to heal. Open fractures are particularly serious because, once the skin is broken, there is a higher risk for infection in both the wound and the bone. Immediate treatment is required to prevent infection.

KNEE3 BALANCE IN MOTION
Knee3 is a new approach of software-guided surgery for knee replacement procedures providing the flexibility to manage unforeseen circumstances on-the-fly and supporting surgeons with beneficial information during surgery. A continuously updated graph measures and charts the range of motion of the entire knee joint based on the actual geometry of the selected implant model, prior to performing any cuts.Patient friendly case reports help educate and engage patients about their software guided surgery.
