Which type of healing is characterized by the formation of granulation tissue?

Secondary intention healing is characterized by the formation of granulation tissue as part of the healing process. In this type of healing, the wound is allowed to heal from the bottom up, and granulation tissue forms as a key component of this process. Granulation tissue consists of new connective tissue and tiny blood vessels that develop on the surface of a wound, providing the foundation for new tissue growth.

This healing process typically occurs in wounds that are larger, deeper, or have edges that are not easily approximated. The presence of granulation tissue indicates that the body is actively working to fill in the wound with new tissue, ultimately leading to the formation of a scar. Understanding this process is essential in orthopaedic rehabilitation, as it affects wound care, the timing of interventions, and expectations for recovery.

The other types of healing do not involve granulation tissue in the same manner. Primary intention healing is typically associated with clean, closed wounds with minimal tissue loss, while tertiary intention healing involves delayed closure of a wound, often after a period of time where granulation tissue might form but not as a primary mechanism. Immediate closure healing is not a recognized category in traditional wound healing classifications. Understanding the role of granulation tissue in secondary intention healing highlights the complexity
