In reply to Goonie:
i've been responsible for a fair bit of ACL rehab
she can expect some early walking correction and gentle balance work to start with
An ACL is very weak at about 6 weeks as the graft is starting to die due to lack of its own blood supply which starts to form at abot 6 - 8 weeks, from then it gets stronger and stronger. thats why you won't have too much loading until after that period as its so weak.
after that she should start having strngthening work, light jogging and change of direction stuff
start to finish about 6 months
patella tendons can be just a s good as hamstrings. i know a guy who had one of each and says he can't feel a difference.
make sure she sticks to the physio program and i wouldn't climb for about 3 months - just not worth risking it, you may get away with it but is it worth the risk?
