How to Treat Scraped Knees at Home

August 23, 2019 | Family Medicine

Scraped knees are a childhood rite of passage. No matter how common these minor injuries may be, however, parents are bound to be worried about how to treat them properly.

The good news is that, in most cases, parents can safely treat minor scrapes, cuts and bruises at home. However, to avoid infection or other complications, you must keep an eye on the wound.

Steps to Treating a Scraped Knee

Whether your child sustained a scrape from falling off a bike or tripping on the sidewalk, these injuries almost always occur outdoors. This increases the presence of germs and the chance of infection, so be diligent about washing your hands before you begin treatment. Also, keep little hands from touching the open wound.

Once you’ve washed your hands thoroughly, recommends following these steps for treatment:

  1. Apply direct pressure to stop the bleeding, using gauze or a clean cloth.
  2. Gently wash the wound with soap and running water for five minutes.
  3. Use a clean washcloth, if necessary, to scrub out any dirt or debris in the wound.
  4. Let the area dry thoroughly after cleaning or pat dry with sterile gauze.
  5. Apply antibacterial ointment to the wound and cover with a bandage or dry gauze.

Change the bandage daily, checking for signs of infection each time. You can also use a liquid skin-type bandage. This product is waterproof, provides a more complete seal and can last for several days. This may speed healing and prevent infection better than an adhesive bandage.  


When Should You See a Doctor for a Scraped Knee?

Seeking medical attention under the following conditions:

  • If your child sustains a scrape that bleeds excessively, or if bleeding does not stop after 10 minutes
  • If dirt or debris remains in the scrape after 15 minutes of flushing under running water
  • If the scrape covers a large area or if the skin loss is deep
  • If your child does not have a current tetanus shot
  • If your child is less than 1 year old

If you believe your child requires medical attention, contact your family physician or an urgent care facility.


Watch for Signs of Infection

Most skinned knees heal within one to two weeks. However, if you notice any signs of infection, contact your family medicine practitioner. recommends seeking medical attention if the wound site swells, becomes red or hot, develops discharge or has a foul odor. 

If your child develops a fever, this may also indicate the presence of infection. 


How to Minimize Scarring from a Scraped Knee

Depending on the location and severity of your child’s injury, cuts and scrapes may scar during the healing process. 

You can minimize the appearance of scarring by keeping the wound moist with petroleum jelly, according to the American Academy of Dermatology (AAD). If you keep the area clean, the AAD advises that using antibacterial ointment is not necessary. 

Once the wound heals, be sure to protect the area from the sun, as UV exposure can increase scarring for up to six months. Liberally apply a broad-spectrum sunscreen with an SPF rating of 30 or above and reapply frequently for best results. 

If you have questions or concerns about your child’s scraped knee or other injury, contact your family doctor.
