Patellar fracture surgery is a surgical procedure to restore the original misaligned bone to its original position without any change in the size of the bone during the entire procedure. At the beginning of the fracture, there is a very obvious swelling around the patella, and after the fracture surgery, due to the long period of inactivity, the swelling subsides and the muscles around the knee joint atrophy significantly. When these two conditions are intermingled, the bone may become larger than it was, especially when compared to the hind leg, but this is only a comparison, not a corresponding change in the size of the bone, so no special treatment is needed, only regular review of the fracture can be taken to observe the healing. Only when the fracture is completely healed, you can slowly and gradually walk on the ground and return to your normal life level.
