Cross post EL. See what the phys says but I would have thought you'd have enough time to work on your glutes and ITB to see significant improvement before April. Depending on what the phys says, a few weeks to get your knee right still gives you time to put in enough quality training for a get-you-round plan. I wouldn't give up hope yet.
Sorry to hear that TD. I think the cold weather is contributing to a lot of injuries at the moment - everyone's just a bit more tense and the muscles are colder.
One of my favourite core exercises is staying upright on public transport. Use your core when standing on the bus or the train instead of holding on. Works a treat and you can do it twice a day if you commute.
A probably inadvisably long run for me today but I wanted to test my fitness levels against this time last year. In effect, I did this week's medium and long runs together. Worked OK and gave me a good idea where I am, but I won't go that long again for a while.
BG - ow. You have my sympathy - I've had a similar experience (only I was salsa dancing at the time, which is another story). Until you see the phys, try to limit the damage by icing, keeping it elevated, and wearing a calf guard if you have them (or even a good old-fashioned elastic bandage). That should help to keep the swelling down.
TD - I have to use the fake tan to even out the odd patches from running wearing various combinations of short socks, calf guards, trail shorts and normal shorts. Otherwise I'd spend all summer with weirdly brown knees, as they're the only part of me that's consistently exposed to the sun!
