Sorry, don't mean to commandeer this thread, but to answer the question...
This is going to be long, but since it has meant a big change in my life, I have much to tell...
The short of it is I tore the medial meniscus on my right knee. Unfortunately I did it in September of 06, but did not have surgery until the end of February 07, which is the reason I am still sidelined now. I was lucky (depending on how you look at it) in that the tear was in the vascular region (red & red/white zones) of the meniscus, which is a repairable area. Typically you tear the non-vascular area and part of the meniscus is just removed. However this sets you up for more pain, arthiritis and eventual knee replacement if they remove enough of the meniscus. So, the fact that it was repairable was fortunate. However, unfortunately the meniscal repair comes with 7-12 months of rehab whereas a partial menisectomy (removing part of it) takes 6-8 weeks. The reason is even though the "red zone" has blood flow, it is very minimal and thus takes a very long time to heal thoroughly. So, in the long run it is much better to have the meniscus repaired. In the short term it means I'll miss most of or all of the 2007 kiteboarding season.
How I did it...plain bad form. For some reason I always send the kite on an S-bend. And despite many attempts to correct this, I was never able to. Once I sent the kite so much I ended up doing an S-bend kiteloop (albeit an ugly one). But because of that I had the notion that I would just commit to pulling the trigger a bit more and would do s-bend kiteloops instead of bad dangly straight s-bends. In September I went for one, except went off a wave and got much higher than I ever have...which messed me up a bit and I didn't commit enough on the kiteloop. So, the kite ended up to one side and then crashed. Unsupported in the aire, I came down hard and tried to land on my board (BIG MISTAKE!!). I basically landed very hard and flat and crumbled over my board. If I had only landed on my butt things would probably be very different. And, if only the story ended here things might be different as well. So, I relaunched and rode back upwind to the launch site. The knee was sore but not horrible and by the time I got to where I launched from my knee was feeling better. So on my last run in I figured I'd end the day on a high note and did a raley to blind. All I heard and felt was a big POP in the knee! Stupid!!!
The 1st MRI was fairly inconclusive and it was recommended I lay off the knee for a month then do rehab. Which I did. During rehab my knee felt better for a while, but then around December it took a turn for the worse. 2nd MRI showed possible ACL tear and definite meniscus tear. It took til Feb to have surgery. Luckily the ACL was found to be intact. So, after being on crutches for 6 weeks, in a brace for 2 more and starting rehab 2 weeks ago...I have a right leg that resembles something from a chicken and a knee that doesn't and can't be bent past 90 degrees until late May.
Hopefully I'll be back by late August or September.
My new mantra is "When in doubt, land on your butt".
