SAM, I missed the whole getting angry bit, but after dealing with ortho's and physio I can fully understand and relate to being mad, being held in the dark etc.. upon my questions about cycling, running and boxing after knee surgery, I got a no. after asking about pain when I crouch I got told " you can walk, you are fine" so yes, foul language and ill tempers are in the order of the day. I had a torn acl, repaired meniscus and bruised femur. op to repair meniscus was done in nov, no more acl no recon. I can cycle fine and even started jogging again (against dr's orders but it works for me - just have to deal with other muscles that over compensates). I did a lot of research and found many information about people who went back to jogging after full knee replacements. So I really don't think cycling would be an issue. points of interest Sports science institute is probably your best bet (also, when going to a phsyio - look for one that specializes in sports otherwise you are going to waste you time) take it easy with the recovery, start slowly and very gently build yourself back... aim for 9 months recovery time start with physio as soon as possible. the last point, I think makes the major difference, and is why I like ssi in cape town. traditionally dr's will keep you in a brace with restricted or no movement for 6 weeks. in these 6 weeks your knee will do alot of healing but you will also grow stiff and have no flexibility as well as a wasted quad muscle. (not sure if it will go exactly the same ) with SSI you go in and out on the same day and start with rehab the very next day. I think that counters the issue mentioned above and helps plenty with retaining flexibility and muscle structure.
