I have had meniscus surgery twice. Once on my left and once on my right.
MAKE SURE you educate yourself and faithfully follow all of the seemingly annoying rehab. The most important part of the rehab process is working on the small muscle groups and implementing all of the appropriate exercises. It's much more enticing to just hit the gym and do all of the "obvious" leg workouts, but that is a mistake. Leg curls, extensions, lunges, squats, those things only help later and in conjunction with the "small muscle" exercises.
Also get your motion back within 48 hours. It will help avoid blood clots and speed recovery. Check out Duke University, they did a study on their athletes recovery from meniscus surgery and its really enlightening. I followed their program and was boarding after 6 weeks. They recommend being on a stationary bike after the first 48 hours (lightly) and it works. If you skip any rehab it will set you back exponentially.
