What to do if your knee hurts after being hit

Knee pain after being hit if it is a simple soft tissue injury, can be treated by rest, cold compresses, drugs; if accompanied by fractures can be treated by external fixation or surgery.
The knee area, especially in front of the patella, is not covered by abundant muscles, and most of the post-traumatic pain is more obvious. If it is a simple soft tissue injury to pay attention to rest, reduce walking. Use cold compresses such as ice to induce capillary contraction and relieve pain. You can also take oral non-steroidal anti-inflammatory analgesic drugs anti-inflammatory pain relief, such as nimesulide, celecoxib and so on.
If the impact is strong enough to cause patellar fracture or periprosthetic fracture, the fracture can be fixed in a conservative plaster cast if the fracture is not displaced, and if it is displaced, it needs to be cut and repositioned with internal fixation treatment.
If the knee is painful after the impact, it is recommended to go to the hospital to receive regular treatment.
