Why Won't My Quad Turn On After ACL Surgery?
Your quad won't fire after ACL surgery? In most cases your brain has turned it down to protect the knee. What is happening, a free exercise to try today, and what to do if it still won't turn on.
ACL recovery, from the day of the tear to the day you are cleared: timelines, prehab, the quad that will not fire, and getting back to the sport.
Your quad won't fire after ACL surgery? In most cases your brain has turned it down to protect the knee. What is happening, a free exercise to try today, and what to do if it still won't turn on.

Zach's answer on the Kneed To Know podcast: start prehab before surgery, get range of motion back once your surgeon allows it, and get the quad working early.

Zach explains the most common reason he sees athletes fall behind after ACL surgery, and the pain levels he lets them work through when they return to sport.

Most high school and college athletes return to sport about 9 to 12 months after ACL surgery. Here is what each phase looks like, where athletes tend to fall behind, and how direct current e-stim can help them stay on track.

Direct current e-stim lets you combine a strong muscle signal with movement, which most stimulators can't. Here's how we use it in ACL prehab and what athletes have done with it before surgery.

The exact exercises we use in ACL prehab, in two stages: active range of motion, then yielding isometrics. Each one trains the muscles to work through a full range of motion before surgery.

A quality ACL prehab program uses 4 types of exercises: range of motion, strengthening, neuromuscular training, and perturbation training. Here's what each one does for the knee before surgery.

Your doctor's prehab goals will put you in a better position for surgery. Here are the 8 goals we recommend if you want to go into ACL surgery as close to 100% as possible.

If you're not giving the body the things it needs to recover in between workouts, you're going to limit how efficiently you can recover. This article covers protein: how much you need after ACL surgery and how to get there.

We receive a lot of calls from parents of high school athletes who have just torn an ACL. I tried to envision what I would want my own daughter to know within the first 24 hours of tearing an ACL.
