In tendon healing, which event occurs in the first 4 days?

• A. Inflammation occurs in first 4 days
• B. Collagen synthesis in first week
• C. Fibroblasts migrate from adjacent tissues
• D. Remodeling for 2 months

Answer: (A)

In tendon healing, the immediate response to injury is inflammation. Right after the injury, the body forms a clot and vasculature reacts, bringing immune cells to the site. Neutrophils arrive within hours and macrophages follow over the next couple of days to clean debris and release signaling molecules that kick off the repair process. This inflammatory phase is most prominent in the first few days, including the first four days, and sets the stage for the subsequent proliferative repair phase. Collagen synthesis by fibroblasts begins as repair progresses, typically becoming more active in the proliferative phase after the inflammatory response has started, often in the first week. Remodeling, where the tissue reorganizes and strengthens, happens over weeks to months. So, the event that occurs in the first four days is the inflammatory response.
