I have had three arthroscopic surgeries on two knees (go figure)
Here is the complete stories from my blog:

It is a collection of posts about all of the injuries I have had(most from clowning)
Long story short(er):
In 2004 I wa having a lot of knee troubles on my left knee, so I went in to see my doc and he referred me to an orthopedic doc. I went and saw him and after wrenching my knee around to ask if it hurt(which it did) and doing a few x rays he stated that most likely I had torn my meniscus. I went in for surgery everything went fine until recovery when we figured out that I am allergic to codeine.
The night of my surgery I had an attack of the horrible itches and had to stop taking all pain killers except alleve. I also had to take a bunch of benydryl to stop the swelling\itchiness.
Basically it sucked. I was back to my old tricks in about 10 days and fully recovered in 3 weeks.
Flash forward to fall 2006. Knees(both of them) still bothering me, many x-rays later and it turns out that due to the physical nature of everything that I do, my muscles\tendons etc had caused my knees to by crooked.
So I had two surgeries in a month, one on each knee, and discovered after the first one that vicodin is also not really my friend. So my third and final surgery I had no post surgery pain meds that I could take.
Other then troubles with meds everything went fine. I am able to do everything I could normally do and was fully recovered in about 6 weeks from the final surgery.
I would say that if your insurance will cover it you should try to get a cold therapy machine. If you want I can get you more info or at least a link to their website.
Basically it is a machine that circulates cold water around your knee while applying pressure. I had it for my last surgery and that knee felt recovered faster then the one that was operated on four weeks prior. They are awesome.
Anyway, good luck and you will be fine. Just make sure you do the physical therapy.
