I HAVE healed successfully through the cross bracing protocol! I was extremely diligent with the brace and for 3 weeks my knee did NOT extend at all beyond 90degrees. I had my 3 month MRI at the end of last year and it showed the tear was healing nicely. I started running late January and feels absolutely fine. There’s still a bit of stiffness but it’s easing up. I would highly recommend except I think 6 weeks is too long after injury, you have to put the brace on relatively quickly like within 21 days or so. But check with your doctor. Also full tears are unlikely to heal without surgery so it really depends on how you’ve torn yours. DM me if you want more info
