Replying to Knee brace help

So late November in 2014 hurt my knee in lacrosse, went to the doctor got an mri and had a partial tear in my meniscus, but it didn't hurt too bad and the doctor said I really didn't need surgery. Skied a couple of days very lightly and didn't hit anything, and then started physical therapy to get ready for lacrosse season. My doctor gave me a nice orthopedic brace to wear for playing sports so I used that for a couple of months until the pain stopped, worked my ass off in the gym all summer and fall in the gym and now I feel like I'm almost at 100%, I have a few days on snow this year and it feels great, I'm taking it slow but both of my knees get sore after skiing. I feel like I'm too strong to wear the orthopedic brace, but I don't want to injure it again. Should I wear the brace my doctor gave me or buy compression sleeves for both of my knees?
