Here’s a clip of my chat with Meagan talking about ACL recovery and her own journey back to playing for the Dominican national team after her 2nd tear on the left knee.
The knee can look “symmetrical” and still be miles from recovered.
New research from Matt Jordan (Frontiers, 2022) tracked elite alpine ski racers — including World Cup medalists — for years after ACL surgery.
These athletes had full-time coaches. Sports medicine teams. The best rehab money can buy.
Here’s what he found 👇
🔹 Between-leg symmetry normalized at ~2 years
🔹 Eccentric deceleration impulse (your knee’s brake) stayed depressed 5+ years
🔹 Jump height — still below pre-injury benchmark at 5 years
🔹 Peak power — plateaued and never fully returned
🔹 Reactive strength (RSI-mod) was the one metric that did recover
So why didn’t more training fix it?
According to Jordan, it’s not a training volume problem.
After ACL surgery, the nervous system installs a protective brake: less quad firing, more hamstring co-activation, reduced voluntary muscle activation. The brain is guarding the new graft.
That protective pattern can linger for years — even in athletes who train at the highest level on the planet.
His recommendations:
✅ Stop relying on side-to-side symmetry only. Two equally weak legs = a “passing” score that hides the deficit
✅ Use absolute benchmarks vs. age and sport-specific norms — not your “good” leg
✅ Measure the eccentric phase of jumps, not just jump height
✅ Target the specific phase that’s deficient — eccentric brake, concentric drive, or terminal takeoff
✅ Keep monitoring for years, not months
The takeaway:
Symmetry isn’t recovery.
And more reps won’t outrun a neuromuscular pattern your brain installed to protect your knee.
You have to measure what’s actually deficient and train it on purpose.
That’s the foundation for a full recovery back to the highest level.
And that’s what my new app, is built on.
