Dr. Kaan Celebi | ACL Rehab Specialist on Instagram: "Comment ACL and I’ll help you rebuild your quad strength after ACL surgery. Your quad isn’t just a muscle, it’s your knee’s main stabiliser. After surgery, it shuts down due to nerve inhibition, and random exercises won’t fix that. We re educate it step by step: activation → controlled load → symmetry → power. When your quad hits ~90% of the other leg, that’s when running and plyos actually make sense, not before. #quadstrength #aclrehab #acl

If your quad won't fire after a knee injury, it is not your mind playing tricks on you. There is a real process behind it called arthrogenic muscle inhibition, or AMI. After an injury or knee surgery with a lot of swelling, your body will shut down the muscles that stabilize the knee joint, mostly the quad. That happens because a muscle contraction can sometimes cause more damage to an already injured joint, so your brain turns it off to protect you. The problem is that eventually you need that
