What should I do if the scar bulges after a knee injury?

Generally, if a scar on the knee becomes raised after an injury, it can be improved through methods such as cold and hot compresses, topical medications, and laser therapy. Details are as follows:

1. Cold and Hot Compresses

After a knee injury, local soft tissues may sustain varying degrees of damage. If there is a scar in the area, swelling may occur. Initially, apply a cold towel for cold compression; after 24 hours, switch to heat application, which helps promote blood circulation and reduce swelling.

2. Topical Medications

When necessary, under medical guidance, topical agents such as safflower oil, swelling-relieving and pain-relieving tincture, or Yunnan Baiyao aerosol spray may be applied to alleviate swelling and relieve pain.

3. Laser Therapy

If the scar swelling is more severe, treatments such as carbon dioxide laser or fractional laser can be used. These employ specific light sources to irradiate the affected area, helping reorganize local fibrous tissue and remove scar tissue.

In addition to the above common treatments, scar dermabrasion may also be considered. Proper skin care should be maintained during treatment. If symptoms do not improve during treatment, timely medical consultation is recommended. Early diagnosis and active cooperation with medical treatment lead to better recovery outcomes.
