Hello John
How are you ?
I am very interested in hips and have tried to understand the significance of the different scores

Right bear with me on this.......lol
I have been told that if a score is of the example you gave, 0-20, as oposed to 10-10, then the lower score is the one that matters, as in this case 20 is more likely to have been damage which was caused as a result of an injury. This is only in the case where one hip is significantly higher than the other.
Now tell me I am being given rubbish info.........lol
Regards
Paul
