Knee surgery??

Anybody ever have knee surgery??Just had orthoscopey..Ouch!This is the 3rd time in 20years after major reconstructive surgery(2 torn ligaments)Now i,ve had this done a couple times before,but this time it seems to hurt a hell of alot more(age45)I also have 3 h.discs.So gettin comfortable is a little harder.I,m of work for a bit so good time to play mechanic again.I have my center section out and clutches are done.I was thinking on spool but I just got a call for a s.g with 3.91.The guy apparently rode the car off and pulled c.section so I offered 200 bucks and he said yes.Is that a deal or what??It will be at least a week before I get some more movement to install,I,ll keep posted..
