IThis link will give you more info...
But basically, it's bilateral (both sides) hip displaysia with secondary arthritic changes in the knee joint. That's what I see in the x-rays. Her left hip joint (right side in x-ray) has major structural changes and is more than likely causing pain/discomfort. This will cause the dog to change its gait and put more strain on other joints, causing early wear and arthritis. The right hip isn't as severe, but there are arthritic changes to it as well as shallow sockets.
Sorry to be the bearer of bad news, but your baby has pretty severe hip displaysia. With surgery and medical management, she can be comfortable. Unfortunately it will effect her quality of life as she ages.
Anyway... welcome! There is a ton of great info here, and a lot of info on displaysia.
