- Inflammatory phase resolution
- 5–7 days
- 4–5 days
- Sustained IGF-1 accelerates macrophage-mediated debris clearance
- Earlier initiation of proliferative phase
- Satellite cell activation peak
- 48–72 hours post-injury
- 24–48 hours post-injury
- Higher circulating IGF-1 reduces latency to stem cell recruitment
- 40–60% increase in activated satellite cell percentage
- Return to 80% baseline strength
- 6–8 weeks (grade II tear)
- 4–6 weeks (grade II tear)
- Accelerated collagen deposition and myofiber fusion
- Reduced atrophy and earlier functional recovery
- Re-injury rate at 6 months
- 18–25% (published cohort data)
- 8–12% (observational, not RCT)
- Improved extracellular matrix organisation during remodelling
- Lower incidence of secondary tears at original site
- Professional Assessment
- Passive rest allows natural healing but leaves performance gaps during proliferative phase
- MK-677 compresses recovery timeline without altering injury severity classification. Most beneficial for grade I–II tears where surgical intervention isn't indicated
