"...I haven't gotten into the full rehab process. I hear that's a little tougher."
Yes, John, it is. I don't know how many of you guys have had major surgery on joints, but speaking from experience, the rehab is BRUTAL. I tore my kneecap in half playing softball and once rehab started I thought I'd never be able to bend it again. I was biting on a towel to keep from screaming when the therapist was bending it only a few degrees! Once you get motion, then you have to start strengthening all those muscles that atrophied...ugh. I really do marvel at the modern athlete and their ability to come back from some pretty serious stuff.
