When Scar Tissue Becomes a Problem
(Why it forms, when it matters, and when it actually holds you back)
Scar tissue gets a bad reputation, but the truth is nuanced.
Scar tissue is normal. You can’t heal without it.
But sometimes it forms in a way that becomes a real mechanical problem — and that’s when patients feel pain, stiffness, or long-term limitations.
Here’s when scar tissue actually becomes an issue.
1. When It Forms Too Thick or Too Dense
After surgery or significant injury, the body often “overbuilds” during the repair phase.
Dense fibrosis can:
Limit joint mobility
Create a stiff end-feel
Cause chronic tightness that never quite goes away
This is common after knee surgeries, rotator cuff repairs, and hamstring strains.
2. When It Glues Tissue Layers Together
Different tissue layers need to glide — skin, fascia, muscle, tendon.
Scar tissue sometimes binds them.
This can create:
Pinching
Catching
A “stuck” feeling
Pain with movement
Difficulty getting into end range
Think: IT band friction, post-C-section scars, and post-arthroscopy portal sites.
3. When It Limits Full End-Range Motion
This is the biggest red flag.
Examples:
Can’t fully straighten the knee after ACL surgery
Shoulder stiffness after rotator-cuff repair
Limited ankle dorsiflexion after ankle sprain or surgery
If you lose end range, everything upstream and downstream compensates.
4. When It’s Painful Because It’s Disorganized
Certain scar tissue ends up:
Highly sensitive
Irritable to pressure or stretch
Full of small nerve fibers
Patients describe it as sharp, burning, or “grabbing.”
5. When It Keeps Re-Tearing
Weak, messy scar tissue doesn’t tolerate load.
It breaks down → repairs poorly → builds even more scar tissue.
This cycle is common in tendons, hamstrings, and calf strains.
Bottom Line
Scar tissue isn’t automatically bad.
It only becomes a problem when it limits motion, alters mechanics, or becomes painful.
If you’re stiff, stuck, or plateaued months after injury or surgery, scar tissue may be the reason — and it’s fixable.
We’ll continue this series next week with real-world examples and case types where these methods make the biggest difference.
