Testimonial: "I Got My Life Back"

Recovering from Arthrofibrosis Due to Model 200

I just wanted to reach out and say thanks. I purchased a Model 200 back in March, 2025 and it has been as much of a game changer as you promised.

I had full ACL and MCL reconstruction (plus some other bits done) back in November. I got the best surgeon I can find, 20+ years of experience, works with Olympic level athletes and gets them back to competition.

I developed what he described as “the most severe case of arthrofibrosis he had ever seen” in his entire career. I had a follow up scar tissue removal surgery in February. My physio and surgeon were honestly stumped, as my ROM was regressing day by day after surgery.

I had literally gotten to the point I would split my 8 hours of sleep into shifts, sleeping 4 hours, waking up to do rehab exercises and then back to sleep for another 4 to prevent being immobilized for too long. Literally doing everything I could and nothing was working.

Within a week of using the Model 200 I was in a materially different place. My physio was honestly blown away. I was going to see him 3-4x a week at least, and after I got the machine, he literally told me to stay home and just use that, it was better than anything he could do for me at that point.

I started going in once a month to get checked up. Progress consistent, got cleared for strength training, and today I got cleared for impact. Started doing jumping exercises, etc. 2 weeks from now I’ll begin running.

Martial arts is a massive part of my life, and my surgeon now believes by early next year I could be back to 100% if we keep going at this rate.

MASSIVE THANK YOU. YOU SAVED MY LIFE.
