Multiple theories have been discussed, including skewed X chromosome inactivation or the reactivation of inactivated X chromosome causing overexpression as causes of increased prevalence of ADs in females.20-22 Certain subgroups

Hyaline cartilage ECM contains low densities of type II collagen fibers and an abundance of the proteoglycan, aggrecan, composing the ground substance. Water molecules embedded in the collagen matrix give
