Wound management

Hello Dr.
Huang,
I fell while running and have a wound on my knee where approximately 2x2 cm of flesh has been removed, and the wound is deep enough to expose the fat layer.
After being taken to the hospital, the doctor asked my family to search for the removed skin.
What is the likelihood of successfully reattaching the skin? Additionally, how deep must the skin be removed for it to be necessary to retrieve it for suturing? What types of books or websites should I consult for detailed information on these topics?
Thank you! Wishing you health and may all your wishes come true.
Best regards,
Xu

Ms.
Hsu: 1.
Hello, based on what you mentioned in your letter, the success rate of skin grafting should be greater than 50%.
As long as the procedure is timely and there are no complications from infection, along with your cooperation, skin grafting typically succeeds.
It is crucial to avoid excessive movement that could prevent the graft from adhering properly, which could lead to failure.
This concern is particularly significant for the left knee, as the tension during movement is substantial unless the area is immobilized with a cast.
It would be best to discuss this with your attending physician.
2.
The extensibility of skin tissue varies in different parts of the body, so the size at which suturing becomes impossible and skin grafting is necessary truly depends on the individual and the location (as tissue thickness and extensibility can differ among individuals), and it is significantly related to the depth of the wound.
This requires clinical evaluation for an accurate assessment.
3.
You may need to consult relevant literature in plastic surgery or search for "skin graft" as a keyword; you might find the information you are looking for.

More Info

When it comes to managing wounds, particularly those that involve significant tissue loss such as the one you described on your knee, understanding the principles of wound healing and skin grafting is crucial. In your case, where a 2x2 cm area of skin has been removed down to the fat layer, the management plan will depend on several factors, including the depth of the wound, the condition of the surrounding tissue, and the availability of the excised skin for potential grafting.

Skin Grafting Success Rates
The success rate of reattaching the excised skin (also known as a skin graft) can vary widely, but generally, if the tissue is viable and there is no infection, the success rate can be greater than 50%. Factors that influence this success include the timing of the grafting procedure, the condition of the grafted tissue, and how well the wound is managed post-operatively. If the skin is retrieved and reattached within a few hours, the chances of successful integration increase significantly.

Depth and Extent of Wound
Regarding the depth of the wound and when to consider grafting, it is essential to understand that skin has varying degrees of elasticity and thickness depending on the body part. In general, if the wound extends beyond the dermis into the subcutaneous fat layer, it may not heal properly without intervention. The need for a graft typically arises when the wound is too deep for primary closure, meaning that the edges of the wound cannot be brought together without tension.
In your case, since the wound is deep and has lost a significant amount of tissue, it is advisable to consult with a plastic surgeon or a specialist in wound care. They can assess the wound's characteristics and determine the best course of action, which may include grafting or other advanced wound care techniques.

Resources for Further Information
For more detailed information on skin grafting and wound management, you may want to explore resources such as:
1. Textbooks on Plastic Surgery: Look for chapters focusing on skin grafting techniques, wound healing, and management of complex wounds. Books like "Plastic Surgery: Volume 1: Principles" by Peter C. Neligan can be quite informative.

2. Online Medical Databases: Websites like PubMed or Google Scholar can provide access to research articles and reviews on skin grafting success rates and techniques.

3. Professional Organizations: The American Society of Plastic Surgeons (ASPS) and the Wound Healing Society often have resources and guidelines available for both patients and healthcare professionals.

4. Clinical Guidelines: The National Institute for Health and Care Excellence (NICE) and other health organizations often publish guidelines on wound management that can be very useful.

Conclusion
In summary, the management of your knee wound will require careful consideration of the depth of the injury, the potential for grafting, and the overall healing process. It is essential to follow up with your healthcare provider to ensure that the wound is monitored and managed appropriately. Proper care and timely intervention can significantly improve the chances of successful healing and minimize complications. Always prioritize open communication with your medical team to address any concerns you may have during your recovery process.
