Had my meniscus repaired 9 months ago after tearing it in the surf so bad my leg was stuck in a bent position and i couldnt put ANY weight on it, it sucked. Stayed in pismo for two days trying to figure out how to drive home(right knee,leg) to sac. What an adventure that weekend and subsequent following 7 month rehab.
There is a huge difference between a repair or just having the tear removed. Depending on if the meniscus just tore or if it was a bucket handle tear like I had you have two options. Mine tore but was still connected on both ends resembling the handle of a bucket. First option is to see how much tore, percent wise, and if there is a good chunk tore and it can be repaired(stitched back to the meniscus)then you have even more to think about Because the recovery time for repairing it is about a 5-6 week period that you can't put any weight on the treated leg and then months of rehab to help the meniscus hopefully connect as well as it can. The benefit about re attaching it if possible is that you pretty much have you entire meniscus. I had a bucket handle tear so I chose the re attachment method which was a long process but I chose that solely because I am 30 and I had such a big tear that I would have had arthritis soon.
luckily the orthopedic surgeon i was able to have do my surgery was dr. Akizuki and he is the sf giants team ortho doctor. Guy was super cool and I had the surgery around 5 p.m. And I was home by 10 having drinks with my buddies, but the next day and following weeks was sore as hell. If you can they rent little machines that you fill a reservoir with ice and water and it wraps around your leg and it pumps the cold water around your knee, waaaaaay worth the rental. Also the have a small device that sits on the couch and you strap your leg in it and it flexes your leg for you if you have the type of surgery that requires no weight bearing because since your sitting its not weight bearing. I sat on the couch and went through tons of ice and water and used the flex machine for hours a day, well worth it.
hopefully yours is just a minor tear and its super easy man, they cut it off and like Andrew said your back to winning bike whip contests. Good luck man, hope it goes well. I didn't ride for 6 months and hope you don't have do that either.
Ohh and worst part about the whole surgery was going back a month later and my knee was huge and doc drained the fluid from my knee, worst pain of my life and that's coming from someone who was kicked in the head by a horse lol
