hip Osteoarthritis and subchondral sclerosis

[Grandlover1]

I have been diagnosed with left hip Osteoarthritis with mild degenerative change in the left hip joint with some subchondral sclerosis in the superior aspect of the acetabulum

I would like to know if we can have hip Osteoarthritis without having subchondral sclerosis

I would like to know if they are two different medical conditions.

I would like to know if the fact that I have subchondral sclerosis makes my hip Osteoarthritis worse
