Has anyone had their ACL and MCL replaced? How long before you could ride on the road, and then back to racing DH or BMX? What kind of rehab did you do? What's best for ACL replacement - your own parts or cadavor? I'm pretty bent out of shape - I haven't really raced in 2 years, and I've been working really hard this winter. The Open is 2 months away, and it looks like I'm out a lot longer than that. Any help is much appreciated.
