This type of scarring would be most improved by scar revision with surgery and microneedling/lasers afterward. Please see an expert. Best, Dr. Emer
Thank you for your photo. Your scar can definitely be removed with a surgical revision in which the old wide scar is excised and new thin scar is carefully put back together. The knee is a difficult area to minimize scarring because of the amount of tension and movement that occurs in that area. You may be asked to refrain from any excessive motion of the knee while you heal so you should keep this in mind in terms of scheduling any surgical treatment. It is important to have a in person evaluation by a plastic surgeon to determine the best treatment options. Hope this helps.

The best step forward is to consult with a plastic surgeon. This scar is best excised. You will trade scar for scar, but at least the end result will be better. Laser is not an option. All the bestDr Davin LimLaser and aesthetic dermatologist
