Judo tips for injury prone mcl?

Partially tore my mcl a few years ago and tweak it here and there. Working on it slowly but feeling weak/scared or mini pops or scares during Randori.

My brace/sleeve has helped but does anyone have experience or tips?

Specifically twisting to my left on my left knee for many throws. Switch to lefty? Any specific throws to avoid or to focus on? I'm also a beginner so many throws will impact my knee with poor form like tai otoshi.

(Side question: if I box orthodox with left foot forward, knowing my injury would it ever be advised to switch to lefty judo?)
