Are knee wraps any good or necessary when I'm squatting around 100kg? I have displaced my left knee couple times while running and I feel bit hesitant about squatting more than my own weight. My physiotherapist said that they are unnesseccary aid and musckes supporting knees get stronger without starps.
Well I have been stuck around 100kg for while. I changed program from 5x5 to 4x10.
I'm really scared popping my knees while carrying weight. It already hurts enough without bar+plates on your back.
telling an anonymous person that you know nearly nothing about to do what "feels right" is assuming people have an in depth knowledge of the human musculoskeletal system which even plenty of doctors do not have
maybe try it in the smith machine first so you cancel out the balancing part and just focus on strenghtening the muscle with a little more isolation or even leg press for that matter?
Do NOT get knee wraps. Especially if your knees are fucked. Knee wraps have been shown in studies to cause deterioration of the joint. You could however, as others suggested get a pair of sleeves. I can recommend

Using the smith machine is a terrible idea, do not listen to the other guy. If you want to break through a plateau the general solution is lower volume+higher weight+more rest between sets. As for knee wraps, I don't really know.
