To heal knee wounds quickly, start by gently cleaning the area with mild soap and water. Apply a thin layer of petroleum jelly or an over-the-counter antibiotic ointment (like Neosporin) to keep the wounds moist; a moist environment speeds up healing and prevents scarring. Cover them with non-stick sterile bandages to protect against dirt and friction, changing the dressing daily. Avoid picking at scabs. If you notice signs of infection?such as increased redness, swelling, warmth, throbbing pain, or pus?please see a doctor immediately.
