The internal fixation material will not puncture the skin when the patella surgery results are good. When the patella is fractured and displaced, surgical treatment can be adopted, and internal fixation materials are usually used to fix the patella in order to reset the patella and stabilize the knee joint, to promote fracture healing, and to avoid affecting the activities of the knee joint. There are various common internal fixation methods for patellar fracture surgery, and the commonly used ones include patellar ring ligation using wires, AO tension band fixation, Kirschner’s pin fixation, screw fixation, and patellar claw fixation. If the wire is used for fixation, usually the end will be twisted into a twist shape to ensure firmness, and the end will be shortened with wire scissors and bent to avoid damage to the skin and soft tissues, which will affect wound healing. Therefore, the internal fixation will not puncture the skin and will not affect the joint movement after the fracture has healed. After patella internal fixation surgery, rehabilitation training should be carried out under the doctor’s guidance, and if any uncomfortable symptoms or abnormalities occur, the patient should consult the doctor in time for review and identification of the cause of the disease.
