A comminuted fracture of the patella usually heals in two to three months. Comminuted fracture of the patella usually requires surgical treatment, because the fracture end of the comminuted fracture will have some displacement, and it needs surgery for reduction and internal fixation, and internal fixation patients can choose wires for tension band fixation, patellar ring sutures, wires or steel nails for fixation, etc., which can be chosen according to the doctor’s advice. After correct treatment, usually two to three months can be completely healed. After surgery, patients are instructed by their doctor to perform progressive functional exercises and to help strengthen the leg muscles with more leg massages to improve the range of motion of the knee and reduce stiffness to prevent the formation of venous blood clots. Normal activities can be resumed slowly in about two to three months, and the internal fixation will be reviewed and removed after one year.
