I've had this done, twice in fact. First was at the same time as my ACL reconstruction. Let's just say that I'm honestly thinking childbirth will be less painful than that was, I'll let you know for sure in 4.5 months. One year later the meniscus tore again and I had to have it scoped a second time. I honestly don't know how big the tear was, I just know it hurt a lot before the surgery. This time was outpatient and I remember waking up the next day at home thinking "Did I really just have knee surgery? It certainly doesn't feel like it." I could walk just fine without the crutches around my home. I think a day or two later it did hurt more, but nothing worse than what it felt like pre-surgery. I was back in PT pretty quick and riding the stationary bike was my favorite, it loosened everything up and made it feel good. I didn't ride then, so I can't tell you how long until I was riding . . . but I know I was hiking (steep, very rocky terrain) and golfing inside of 3 months. Everyone (doc, PT . . .) recommended swimming, but I didn't swim then either.

My best advice is ICE, ICE, ICE! I didn't do this enough after the first surgery and the swelling took months to disappear completely. After the second round I iced much more frequently and it helped reduce the swelling quickly (obviously it was a much less invasive surgery, but still). Also elevate, which I know can be tough at work. But when I'd get home I'd lay on either the couch or my bed, or the floor for that matter, on my back with my feet up on the wall to really get that knee above my heart. Get one or two of those ace bandage ice packs designed for knees, they make the process much easier and more effective.

I loved my PT. I know some people hate it, but I don't see why. Based on what Zen said, make sure he gets into PT. I can't imagine trying to do that recovery at home. Good luck with it!
