What should I do if my knee swells after falling?
If your knee swells after falling, you can use alcohol for debridement. Apply local ice pack within 48 hours to reduce swelling. If the swelling persists after 48 hours, you can use a warm compress to reduce swelling. If the swelling is particularly severe and accompanied by severe pain, you need to go to the hospital for CT or MRI examination to determine the location and severity of the injury. Then, targeted treatment can be performed according to different situations, and surgical treatment may be necessary if necessary.
After falling, you can use ice water or cold water to apply ice to the knee to reduce swelling. After falling, the swelling of the knee is due to local bleeding and soft tissue injury. It is recommended to apply local ice therapy within 48 hours after falling, which can reduce the depth of the wound. After 48 hours, you can apply hot compress, microwave, infrared light and other physical therapy locally, which can promote the absorption of bleeding and reduce local bleeding. After cold compress treatment, the knee joint swelling can be significantly reduced, which is conducive to later recovery. During the treatment, pay attention to the wound care to avoid infection, and take oral medication for promoting blood circulation and removing blood stasis as well as antibiotic drugs. Generally, the above treatment can be cured.
1. Ice bags should not directly contact the skin and limbs. Wrap the ice bag in a thin towel, or purchase a cloth cover that fits the ice bag to implement ice therapy "separated by a layer", especially in bony protruding areas, to avoid frostbite.
2. Before formal ice therapy, test for leaks first to prevent wound contamination.
3. In principle, each ice therapy session should not exceed 20 minutes. Long-term placement of ice may damage nerves and other tissues. The interval between two ice therapy sessions should not be less than 2 hours.
