You can look at this as "a weakness" or you can look at it the way I do: as a chronic overuse symptom that I wouldn't be suffering now if I had added a bit more knee protection for my high volume training months ago.
Right now I couldn't train with 225 without wrapping my knees, particularly my left, so the wraps are helping me train through an INJURY more than they're masking a weakness.
"But you CAN'T SQUAT AT ALL WITHOUT THE WRAPS so something is horribly wrong!" come the response.
Well, I have experience with using aids to squat through injury. Back when I had that MCL sprain and chronic, huge effusion that caused muscle atrophy and months of daily draining, I kept training through the pain thanks to doubling up on knee sleeves on my right knee. Initially I had to wear my large Rheband over the medium one or I couldn't squat at all. Was I "masking a weakness" back then? I like to think I was using compression and support to get me stronger and rehabilitate my wasted leg as I took some rather drastic means (self joint aspiration) to get rid of the root problem.
So you can call it "hiding a weakness" if you must. I'm going to do what it takes to allow me to train through the niggling pains that would otherwise stop my training entirely. I want to do at least two more meets this year, maybe three, and I'm not going to work up from 135 to 315 1000% RAAAAAW for four months when using light wraps lets me push much harder while "unfairly giving" me 10 lbs out of the bottom and get closer to that 500 SQ in belt and sleeves at 198.
