Treatment may be with or without surgery, depending on the type of fracture and whether the overlying skin is intact or broken. Conservative Undisplaced fractures can usually be treated by casting. Even some displaced fractures can be treated with casting as long as the person can straighten their leg without help, thus confirming that the quadriceps mechanism of the leg is intact. In this case the leg is immobilized in a straight position for the first three weeks and then increasing degrees of bending are allowed as healing occurs. Surgery Tension band wiring: front and side view Most<unk> s are transverse or comminuted, hence the quadriceps mechanism is disrupted and they are treated by a combination of wires in a tension band construct. This unites the fractured bones, reconstructing the straightening mechanism of the leg. If the patella is broken in several places, that is comminuted, then traditionally a patellectomy (removal of the whole patella) is performed in order to reconstruct the extensor mechanism and prevent the onset of an extension lag at the knee joint, resulting in instability. Some surgeons however would rather opt for internal fixation. A partial patellectomy is removal of only a portion of the patella, and may be carried out if at least 60% of the patella can be maintained. Open fractures of the patella require emergency treatment with irrigation, debridement and fixation. Rehabilitation Irrespective of surgical or non-surgical resolution to the fracture, a physical therapist can advise on progressive weight-bearing exercises and help with strengthening muscles of the leg, improving range of motion of the knee and in reducing stiffness.
