Crikey, it was like my operated leg wasn't my own again! It just felt so weak and wobbly.. "
Ann, I totally remember this. Thanks for that lovely memory!!!

The exercises that we all do for our new hips are not geared toward the dynamics of running. I can't explain which elements are ignored, but they sure are.
So when I started jogging I started very slow....and very short distances (minimal impact and minimal effort) and I really concentrated on making the stride as symetric as possible. I really concentrated on "jogging without a limp". Maybe I should have gone back and started adding the numerous exercises to strengthen the other pieces (my calf, and my ankle and my glute) in a run strengthening way, but I just started small and built up. Then as I noticed components being WAY out of shape and not ready I would do some spot exercises.
One thing that I did at PT that i had done might have helped a bit was
hopping. Kind of like doing a short standing broad jump (if you remember those). I started jumping literally 18 inches with a very exaggerated landing (LOTS of shock absorbtion)..So I'd jump 18 inches (and not high either) and land like I'd jumped 15 feet. I THINK that the hopping gets the fast twitch muscles firing. Walking..even when fast is very controlled. Running (even slowly ) has a fast twitch component that we just don't experience when taking care of our new hips.
But I agree...my inital efforts in running looked like an 8 cylinder engine running on three cylinders. The Brits might say I was all sixes and sevens (don't ask me...THEY said it)
When you are up to it just for fun, try again CAREFULLY and try to be as balanced and symetric as you can, realizing that there are pieces that WILL NOT cooperate.
