From my point of view, with proper stretching and drills I don't think RG can actually hurt someone's knee unless you force it beyond your limit. I practiced rubber guard with my partner since there is no school in my area teaching 10th PJJ.
I use RG whenever its possible while sparring at the gym but I don't really feel pain or uncomfortable at all.
It's important to abandon RG and try different techniques if you failed to lock your opponent up in your RG.
