Tissue Healing 101:
How Long Do Muscles, Tendons, Ligaments & Bones Really Take to Mend?
One of the most common questions I hear in the clinic is “How long until I’m back to normal?”
The honest answer is: it depends—on what you injured, how you injured it and who you are.
But there are well-studied biological windows that guide our expectations and, importantly, shape your rehab program.
The Three Overlapping Phases of Healing
Inflammation (0 – 5 days)
• Vascular “clean-up crew” rushes in, clears debris, generates protective pain and swelling.Proliferation / Repair (3 days – 6 weeks)
• Fibroblasts lay down new collagen, tiny blood vessels grow, tissue scaffolding forms.Remodelling / Maturation (4 weeks – 12 months)
• Collagen realigns under load, tensile strength rises, scar tissue slowly contracts.
Every tissue follows this template, but the tempo differs dramatically.
Cheat-Sheet: Typical Healing Timeframes
*“Good-as-New” = ability to tolerate full sport/work loads, not just pain-free ADLs.
** Degenerative tendons or full ruptures trend longer (16 – 52 weeks, sometimes surgical).
Five Factors That Speed ⏩ or Slow ⏪ the Clock
Blood supply – more vessels = more oxygen, nutrients and growth factors.
Mechanical loading – progressive stress signals cells to align and strengthen tissue; too little or too much both delay repair.
Age & hormones – oestrogen, testosterone and growth factors decline with age, slowing collagen turnover.
Metabolic health – diabetes, smoking and poor sleep cut capillary growth and collagen quality.
Surgical intervention – stabilises major tears/fractures but restarts the inflammatory clock.
Practical Takeaways for Your Rehab Plan
Match the phase, not just the calendar.
Early-stage muscle strains might love gentle isometrics by day 3, while a grade II ankle sprain still needs external support for two weeks.Monitor the 24-hour response.
A slight next-day ache < 3/10 is normal. Escalating pain or swelling? Back off 20–30 % on the next session.Strength beats scar tissue.
Real collagen organisation happens when you load heavy enough—think slow eccentrics for tendons, progressive plyometrics for ligaments, and heavy-slow resistance for late-stage muscle repair.Nutrition, sleep, mindset.
Protein (1.6–2 g/kg), Vitamin C + collagen pre-loading, 7–9 h sleep and a growth mindset literally change the cellular signals that rebuild you.
Worried Your Recovery Is Dragging?
A personalised assessment can pinpoint why you’re stuck—whether that’s under-loading, over-loading or an undiagnosed factor like iron deficiency or relative energy deficiency. As both a physiotherapist and movement coach, I’ll map out a staged program that respects biology and pushes capacity so you return not just healed, but harder to break.
Let’s turn time into progress—smart, intentional, measurable.
