Have you thought about absolutely monster knee braces? And then daily squats. They worked for me. Unfortunately now it’s my neck that’s trying to paralyze me, which would be such a not fun outcome.
When I tore my ACL doing bjj, I was surprised to see that some pro MMA fighters will continue to fight with a torn ACL. They double down on muscles to support the joint and postpone the loss of a year of competition to the reconstruction surgery.
