Which statement best describes scar tissue compared with normal tissue?

• A. Will never be as strong as regular tissue; may limit joint range
• B. Is stronger than regular tissue
• C. Has the same strength as normal tissue
• D. Strength is variable and cannot be predicted

Answer: (A)

Scar tissue has a different composition and organization of collagen than normal tissue. The collagen fibers are laid down in a less organized pattern and with less elasticity, so scar tissue tends to be weaker under tension and stiffer overall. This combination means scar tissue typically does not reach the same strength as uninjured tissue and can form adhesions that limit how much a joint can move. So the description that it will not be as strong as regular tissue and may restrict joint range best reflects how scar tissue behaves. While scar remodeling can increase strength over time, it generally does not achieve the same functional strength as normal tissue, and the mobility limitations are a common consequence.
