Effective Scar Treatment Options for Hypertrophic Scars After Injury - Plastic Surgery

More Info

---

Hypertrophic scars are a common outcome following injuries, particularly when the skin has been subjected to trauma, such as in your case with a knee injury from a car accident. These scars are characterized by their raised appearance, firmness, and redness, which can be quite distressing for individuals. Based on your description, it sounds like you are dealing with a hypertrophic scar rather than a keloid, especially since you mentioned that you have not previously experienced keloids.

Hypertrophic scars occur due to an overproduction of collagen during the healing process. They typically remain within the boundaries of the original wound and may improve over time, but they can also persist and cause cosmetic concerns or discomfort. The good news is that there are several effective treatment options available for hypertrophic scars.

1. Silicone Gel Sheets or Silicone Gel: One of the most recommended treatments for hypertrophic scars is the use of silicone gel sheets or silicone gel. These products can help flatten and soften the scar over time. They work by hydrating the scar tissue and creating an optimal healing environment. It's important to use them consistently, often for several hours a day over a period of months.

2. Pressure Therapy: This method involves applying pressure to the scar using specialized garments. Pressure therapy is particularly effective for larger scars and is often used in conjunction with other treatments. It can help to flatten the scar and reduce its size.

3. Steroid Injections: Intralesional corticosteroid injections can be administered directly into the hypertrophic scar. These injections help to reduce inflammation and collagen production, leading to a softer and flatter scar. Typically, multiple sessions are required for optimal results.

4. Laser Therapy: Various types of laser treatments can be used to improve the appearance of hypertrophic scars. Fractional laser therapy, for example, can help to resurface the scar and improve its texture and color. This treatment is usually performed in a series of sessions.

5. Microneedling: This procedure involves using fine needles to create micro-injuries in the scar tissue, which can stimulate collagen remodeling and improve the scar's appearance. Microneedling can be combined with topical treatments for enhanced results.

6. Surgical Revision: In some cases, if the hypertrophic scar is particularly bothersome or resistant to other treatments, surgical revision may be considered. This involves excising the scar and allowing for a new, more aesthetically pleasing scar to form. However, this option should be discussed thoroughly with a qualified plastic surgeon.

7. Topical Treatments: Over-the-counter creams and ointments containing ingredients like vitamin E, onion extract (found in products like Mederma), or other scar-reducing agents may provide some benefit, although their effectiveness can vary.

8. Sun Protection: Protecting the scar from sun exposure is crucial, as UV rays can darken scars and make them more noticeable. Using a broad-spectrum sunscreen with a high SPF on the scar can help prevent discoloration.

It's essential to consult with a dermatologist or a plastic surgeon specializing in scar management to determine the best treatment plan tailored to your specific situation. They can assess the scar's characteristics and recommend a combination of therapies that may yield the best results. Remember that patience is key, as scar treatments often take time to show significant improvement.
