Robyn - I have a few bits o' info for you. First off, your issue does sound like a kinetic chain problem, but unlike Mr. Silver, I would recommend PT before Chiro. I believe there are many good Chiros out there, don't get me wrong. But I believe there are also many very good PTs that can take care of this problem. Unfortunately, I often see people after they've been through several treatments with poor outcomes. I can honestly say that I see this happen more often with Chiro treatment than PT. I also tend to hear stories of Chiro treatment that does not foster the patient's ability to independently manage their condition. Finally, Chiros tend to use manipulation a lot. As we get older the probability of a serious side effect from a manipulation becomes more of an issue.

Now, specifically regarding this issue. If you have a leg length discrepency, do you have a insert for your short leg that you can use in your cross country boot? This might help. Also, frequent slipping back on the weight bearing ski when you're doing your kick will increase stress on the area you described. You should make sure that you are waxed well to prevent this, assuming you are using waxed skis.

I'd also like to suggest some stretches. They may be same as what you are already doing. In particular, hip stretches are very important for both the pain in your knee and your hip.

I combine these with the usual quad stretches and calf stretches.

I usually recommend holding a stretch for 20 to 30 seconds, repeat 3 to 4 times each side, twice/day until the symptoms are gone then you can slowly taper down to a maintainance schedule of 3 times/week.

Regular yoga classes or Pilates may be very helpful to you.

I hope this helps.
