In reply to weelee9985:
I ruptured my ACL 4 or 5 years ago - is your plan to get an op or to see if you can live without?
Firstly - see a sports physio and get their advice.
Secondly Take all internet advice with a pinch of salt, I found I got lots of well meaning but really dodgy advice off the internet (normally based on I did xyz and it worked fine - no need to see a physio type folk).
Make the effort to find a good sports physio who understands that you want to get back to sporting form (you might need to go private), rather than be OK to walk to the supermarket. A couple of mates I've had who went through NHS with similar injuries were very frustrated by the fact the physios brief seemed to be to get them capable of walking down the street, but not necessarily capable of playing sports again.
I'd be cautious climbing on it (my physio's advice to me was not to climb at all until it was healed or well into recovery)- twisting movements and unusual loading during climbing or knocking it in a fall, twisting dropping off a boulder problem or first couple of moves on a route etc could easily cause more damage or at least prolong recovery.
Between the injury and the Op, my physio had me doing gentle exercise to strengthen quads (but without increasing inflammation) as these were compensating for the lack of ACL and after the op the stronger these were, the less likely I was to re-injure. The basic idea was to reduce the swelling pre-op whilst strengthening the quads up. Anything that caused more inflammation was a definite no.
Walking on good paths (with poles) and cycling were good exercises both post injury and post surgery to strengthen the leg again. Some gym exercises too, but definitely not running or anything else with a lot of impact, or the quad curl type machines (which put a huge amount of load through the joint - really bad during early stages of re-hab, and the later weak periods.
I ended up not climbing between injury in January and about May. Frustrating, but massively less so than re-injuring and having to spend yet more weeks / months off. By the time I was climbing and properly hill walking again I was actually the fittest I'd been in a long, long time as I'd been out on the bike most mornings / evenings for long cycles or in the gym to bring fitness /strength back for months at that point!
Anyway, hope the recovery goes well!
Cheers,
