Well my results are in. The good news is that there aren't any problems with the ligaments or menisci. The diagnosis is chondromalacia AKA torn cartilage in my knee. I have grade 3 tears and flaps that are causing my knee the pain (it locks, grinds, and otherwise feels horrible). The MRI also revealed that I'm dealing with lots of "left-over" issues from my original leg injury (I have an IM rod still in my tibia and some screws). Those left-overs include lots of detritus and even old sutures still floating around in my knee.
They gave me a cortisone shot and I have scheduled PT to hopefully improve my knee cap tracking. We also discussed something called "McConnell" taping to help reduce the pain (I think it's like KT tape). The doc recommends scoping my knee, but I explained that I have ski camp in a bit over a week and I really want to attempt to get through camp. So we're thinking I'll probably have the surgery sometime in early December. He wants to "clean" out my knee and that will hopefully reduce the irritation that's causing the pain. Recovery will take a couple weeks, but I should be in good shape by the holidays.
So my plan of attack is to rest my knee (ice and elevation to keep the swelling down), ibuprofen/naproxen to manage any inflammation and pain, and physical therapy to hopefully figure out a way to tape my knee to control the knee cap tracking and reduce the pain. Needless to say that this has definitely sidetracked my physical preparation and getting some snow time in before camp.
