Which type of healing involves the formation of scar tissue?

• A. Regeneration
• B. Replacement
• C. Reparative healing
• D. Complete healing

Answer: (B)

The type of healing that involves the formation of scar tissue is characterized as replacement healing. This process occurs when tissue is damaged and cannot regenerate to its original structure and function, leading to the formation of a scar. In replacement healing, fibroblasts play a crucial role by synthesizing collagen and extracellular matrix, which ultimately leads to the creation of scar tissue. This tissue serves as a repair mechanism but lacks the full functional characteristics of the original tissue. Unlike regeneration, which restores original tissue, replacement healing entails a change in the tissue composition and function due to scar formation. In the context of post-operative management, understanding replacement healing is important as it informs treatment strategies, rehabilitation practices, and expected outcomes for patients following orthopedic surgeries where tissue integrity may be compromised.
