Detailed explanation-1: -Fibroblastic (Repair) Phase: 4 days – up to 6 weeks During this phase collagen fibers are set down in the damaged area in the form of scar tissue. This type of tissue is less tensile and weaker making it susceptible to damage if overloaded.
Detailed explanation-2: -The time it takes for tissue regeneration depends on the production of collagen proteins by fibroblasts, which is a type of cell found in the connective tissue. This phase of wound healing can last for four days to up to three weeks or more.
Detailed explanation-3: -Once the inflammatory phase has ended, tissue repair begins (22, 24); the fibroblastic repair phase is characterized by catabolism (tissue breakdown) and replacement of tissues that are no longer viable following injury.
Detailed explanation-4: -Acute Inflammatory Phase: Day 1-7. Inflammation has a bad reputation, but acute (fresh) inflammation is actually essential for tissue repair. Fibroblastic Repair/Subacute Phase: Can begin at Day 4, up to 6 weeks. Remodelling Phase: As early as 2-3 weeks, up to months or years.
