First i would like to thank everyone for their answer

To get your feet back in the straps requires a considerable amount of hip flexion. This would be only a problem if you were warned about your hip potentially dislocating.
About the flexibility , seating in a chair i can lift my leg under my shoulder (in height) and the 'good' hip goes just over
This kind of hip surgery has very litle dislocating risk's if any cause the 'ball' is as big or biger than your own

Obviously, this can happen to anyone of us with normal hips but a post-op hip would be a greater risk, most likely.
A lot depends on what you already do successfully with your hip (eg snowboard, ski, surf or just a stroll in the park) and you surgeons advice regarding future risk.
Then main problem with this kind of condition is friction , i mean i swim at a pool about 2k and i have a descend stamina in water also although there is a lot of movement from the leg the actual impact to the hip is minimal cause there is no weight on it. So what i am trying to say is as long as the hip is in motion with litle or no weight has no problem
But to be honest my flexibility is not as good as my other one and also my muscles on this leg (especialy the glutes) are not up to par but this has not stoped me before
Damn... it would be cool to catch some air
