In reply to rexybo: Hi Sam,
I ruptured my ACL/PCL and tore my meniscus in an injury a couple of years ago...
All I can say is the recovery from the surgery is a slow process; the meniscus is a sort of horseshoe shape and doesn't get that much blood flow so healing takes a long time. Usually during surgery they will either cut away the damaged bits or they will fix it; whichever way they go will ease your discomfort, torn mensicus' can often lead to "locking" of the joint where the torn "end" gets trapped in the join (I had this).
Anyway, the brightside...I did all this with an ACL/PCL complete rupture so I had them fixed with a piece of my patella tendon. PCL going strong, ACL has gone again but due to good muscle structure holding every together I'm not going to have more surgery. Once the recovery is over you should be able to climb as normal, i cycle a lot, climb a lot and even get out to the Alps for long weeks of intense climbing and find it's ok.
My advice -DON'T RUSH IT, you'll only do more damage; let it recovery naturally, get yourself a bike or a membership to the local pool and get the muscle structure nice and developed to help your knee.
In my experience you'll be able to climb just fine given good recovery. Basically, don't be a smart arse and listen to the doctors and the physios.
Good luck!
