Sorry I've been incredibly lazy about updating this. I forget that people still check it! I also have been pretty busy with other projects, but kept telling myself I'd do a big writeup on where I was at and all of my thoughts on the injury, surgery, etc., once I hit 50 miles a week. I had my surgery in April, so we're going on 10 months now. My hip has been great and I have not had any loss of coordination to speak of, but I have had a lot of secondary injuries. Mild case of plantar fasciitis, some vague hamstring tightness, several calf issues, and an issue with my talonavicular joint—something just got jammed up there. All of these were on my right leg, the one I had surgery on. Each of those necessitated a week or two off from running each, and I'm just now to the point where I am actually running every single day. I bounce between 20-25min one day and 30-35min the next. I have not done any fast running aside from a few strides once in a while. My calf still likes to tighten up at times and feels worse on hard surfaces (maybe?) and because of that and because I have not done any long or fast running, I can't say I'm "free" of the loss of coordination issue yet. In the fall I was doing 40-50min easy on pavement without issues though, so take what you may from that.
I'll update if/once I'm doing longer stuff. It will be quite a while until I do much faster running, even if everything goes perfect, so don't get your hopes up on me getting back to 100-mile weeks proclaiming that labral tear surgery is the solution to everything. It has been a very long road back and I don't even know if I'll be able to run competitively again. That being said I'm pretty grateful just to be able to do 4.5 miles today. If anyone is considering the surgery, do realize that it is a pretty serious undertaking and it will probably be a long time before you are able to compete again. Not sure if anyone posted this but it was interesting:

Joe Bosshard of CU sounds like he had many of the same issues all of last year and had surgery for a labral tear this past May. From what I know, he did not run at all during cross country, which didn't surprise me given all the issues I was having around that time, and I had my surgery a month earlier! Granted, he has access to all of the amenities of a college team, which certainly helps.
Anyhow that is my story for now. If you are "new" to this issue, the consensus so far is strengthen the heck out of your glutes and abs, and stretch your hamstring. None of the other wacky and sometimes insane "cures" (clockwise circles around the track, orthotics, cell phones, old injections, whatever) have made exactly zero difference for anyone. if you have had this issue for a long time, and especially if you have any hip pain, see a hip doc in your area who knows labral tears in athletes (not easy to find, BTW) and get checked for one. Other possibilities to think about include sciatic nerve issues from the low back, artery issues, or nerve problems, though aside from one herniated disc none of these have panned out for anyone. Anyways I'm rambling. Good luck.
