I had my ACL and meniscus done on May 20th and I am at 100%. Three I was biking on flat terrain within a month and doing small hikes at two months. By four months I was able to go backpacking about twenty five miles ( about eight per day) with a forty lb pack. I am 5.5 months out and hardly think about it any more. There are times when I am scared of doing something but that is because I went 18 years without and ACL. My biggest issue is the muscle memory of doing things a certain way before surgery.
I have a CTi brace and it works fine. It was covered under my insurance and is a perfect fit. They are guaranteed for a year and I send it back for a little refurb around 11 months. The last two times I have done this they replaced all the straps, padding and hardware for free. I had one with a stress fracture and they replaced the brace for free. The brace will occasionally rub my leg raw on the thigh but that's after hiking 10+ miles.
I am pretty hard on the brace wearing it climbing, biking, snowboarding, hiking, sledding, and playing hockey. The CTi is bomber and the warranty kicks butt.
Edit: do all your PT and ride a bike as much as you can. You are through the hard part. Do not push it. Listen to your PT, eat right, ride a bike, ice, ice, ice.
