Subject: Re: arthroscopic surgery

When I had a knee reconstruction (torn ACL, MCL and MMT), I was told that blood
gets shunted away from the injured knee, and because of that, I'd feel pain in
my knee after a dive.

I waited until I was off crutches before diving.  I made it back into the water
before my surgeon gave me the go-ahead, and I was lucky enough not to
experience any problems.
