4. Update: I was listening to your podcast and you said Ice Bug was out of business. I sell them in my store in Fairbanks Alaska where we have snow and ice on the ground for 6-7 months a year. The US distributor is Ice Bug USA. I also carry a the Salomon Snow Cross studded shoe.

5. Email case:

Dear Gaitguys,

I have been on a search since October to determine the cause of my chronic tendonitis in my knees and right hip. Through my search I was told that my femurs are rotated internally and my tibia are externally rotated. This is causing my patella to face inward.

I was told by one PT that I will never be able to run long distances without developing tendonitis. I want to believe he is wrong because I love running. I came across something called Femoral Anterior Glide in my research and was wondering if you guys believe this is a real condition. Also is there a way a person can know if they have this problem?

Thank you for all of your great posts!

Kate

6. Blog reader:

My 11 year old son walks with a very noticeable external tibial torsion. We just recently noticed this and I came upon your site while trying to research it. I also read that many time it has to do with a problem with the patella. Both my husband and daughter have had patella problems but do not have the duck walk like my son. I did ask a a pediatric sports medicine specialist about the problem and he said some kids just walk that way. Where should I bring my son for help with this?

7. Blog reader asks:

About a year ago there was an article posted called: “A case of the non-resolving ankle sprain. Things to think about when the ankle and foot just do not fully come around after a sprain”. I am 15 weeks into an identical problem and I was wondering if there was any way you guys could follow up with “MR” to see if he was ever able to resolve his issue. It is such a unique and frustrating case (being able to walk but not run) and I haven’t found any other instance of it until now. Thank you.

Q: Why do the two of us focus on gait so much ?

A: Because it is such a deeply primary motor pattern that it is all encompassing.

9. From a Blog reader:

Hello the gait guys. I have over pronated rigid cavus along with hallux rigidus on my feet (also had one failed surgery for hallux rigidus on right foot). Having really hard time to be on my feet as well as find shoes and use orthotics. Due to the rigidity of my feet orthotics I’’ve been given create pain I can’t bear and mostly push medial side of my feet. Also without orthotics it is not much better - getting constant pain in my feet and knees. What would be your advise in my situation?Thanks

10. From a blog reader

Question: when my feet point straight my knees point outward from my body. I’ve heard it called external femoral torsion. Is this correct? Also is there any type of PT/stretching I can do to correct this? Would love to get things straightened out (no pun intended).
