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.
Having strong muscles around the joint won't fix a structural problem, but they definitely won't hurt.
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.
You can very likely rehab your knees. Single-leg touchdown squats completely eliminated some serious knee pain I was having with my barbell squats. Also reverse sled drags are a good one. Definitely see a sports/rehab physician or DPT, your family doctor or GP is just going to tell you to "not do that."
