What characterizes Weeks 5-10 in tissue healing?

• A. Maturation phase with peak collagen organization.
• B. Cellular stage with inflammatory cells dominating.
• C. Fibroplasia and early collagen synthesis.
• D. Consolidation; increase in collagen strength.

Answer: (D)

Weeks 5–10 mark the consolidation (remodeling) phase of tissue healing, when the scar gains increasing tensile strength as collagen fibers are reorganized and cross-linked. Early collagen laid down during the proliferative phase shifts from more immature type III to stronger type I, and fibers align along lines of stress, while vascularity and cellularity decline. This remodeling process gradually increases the tissue’s strength, even though complete restoration of original strength takes longer. So the description of consolidation with rising collagen strength best matches this timeframe.
