🏃♀️💥 READY TO RUN AFTER ACL SURGERY? READ THIS. 💥🏃♀️
One of the biggest milestones after ACL reconstruction is getting cleared to start running — but it’s not just about time.
It’s about strength. Real strength.
✅ To safely begin running and impact activities after ACL surgery, athletes should achieve at least 80% Quadriceps Limb Symmetry Index (LSI).
Why does this matter?
Because your quad is the #1 shock absorber for the knee. If one leg is significantly weaker than the other, the body compensates — leading to:
⚠️ Poor landing mechanics
⚠️ Increased knee stress
⚠️ Higher reinjury risk
⚠️ Delays in return to sport
💪 80% LSI isn’t optional — it’s protective.
This standard is backed by research and is one of the first major checkpoints we use at KINISI to keep athletes safe and progressing.
At KINISI, we use force plate testing and objective strength measures to determine EXACTLY when an athlete is ready to run — no guessing, no “it feels okay,” no shortcuts.
Your comeback deserves science, not speculation.
