Injuries to the knee may be general soft tissue injuries, combined fractures, or combined meniscal cruciate ligament injuries. You can first go to the orthopedic department for an interview with a doctor, who will make an initial judgment with the examination and determine the exact structure of the injury through X-rays and magnetic resonance. If there is only a general soft tissue injury, it can be combined with foods that invigorate blood circulation such as yam, Tian Qi, Angelica, etc. If there is a fracture, it can be combined with calcium-rich foods, such as milk and shrimp, to help the fracture heal. In addition, you can eat more fresh vegetables and grains and cereals as appropriate to supplement vitamins. The local area needs rest, avoid excessive local force, and if there is a fracture without obvious displacement, give fixation in time.
