Internal fixation of a patella fracture with steel nails usually does not affect the patient’s ability to walk. When choosing internal fixation of patellar fracture with steel nail, usually the patellar fracture is more fragmented, and the fragmented bone can be pierced up and fixed with steel nail, so that it can heal gradually. After the fracture is healed, the internal fixation of steel nails generally will not affect the patient’s normal life and walking, because the end of the nail will generally be tightened during the operation, to reduce the exposure, to avoid the formation of irritation to the knee joint. However, a few patients will have discomfort when walking after the patella fracture heals, which may be related to the loosening of the internal fixation. It is recommended that the patient should go to the hospital in time to review the X-ray, and according to the condition of the fracture healing, choose the appropriate time to surgically remove the internal fixation nail.
