Hip joints can wear down due to weight-bearing and congruence, leading to fraying of cartilage.

“it's a simpler joint in the sense that it's a ball and socket so it tends to just wear down not to oversimplify now there are some muscles around the hip that act like that we're much more familiar with because of the accessibility of it like the rotator cuff so a lot of the abductor muscles around the hip connect like a rotator cuff does in the shoulder but because of the again the weight-bearing nature of the hip the congruence of the hip it tends to just wear down and that labral cartilage which is the soft cartilage of the hip can get frayed but it's the articular cartilage that really makes a difference”
