If the fracture of the knee is a patella fracture, the patient can still walk on the spot, but there will be significant pain during walking. If the fracture is a distal femur fracture or a tibial plateau fracture, the patient cannot walk on the spot, as follows: first, can walk: the patella fracture does not affect the patient’s normal weight-bearing and walking, but the walking process will induce increased pain symptoms; second, cannot walk: tibial plateau fractures and distal femur fractures are weight-bearing parts of the joint, and walking will cause extremely intense local pain, so the patient usually cannot Therefore, the patient usually cannot walk normally and an X-ray can confirm the exact location of the fracture. Therefore, once a fracture occurs in the knee, it cannot be determined based on whether or not the patient can walk. It is necessary to further confirm the existence of the fracture by taking X-rays and physical examination, and early diagnosis and early treatment are beneficial to the smooth healing of the knee fracture, otherwise, delayed healing, non-healing or even deformed healing may occur, thus affecting the patient’s normal life and sports.
