Search. The hip (acetabulofemoral joint) is a synovial joint formed by articulation between the femur and acetabulum of the pelvis. The head of the femur is cover by type II collagen (Hyaline cartilage) and proteoglycan.The acetabulum is the concaved portion of the ball and socket joint.The acetabulum has a ring of fibrocartilage called the labrum that deepens the acetabulum and improves stability of the hip joint.earch.

Cartilage is enclosed by a layer of dense connective tissue called the perichondrium, except on the articulating surfaces in joint cavities. The perichondrium has two layers- â¦ - a fibrous outer layer and an inner layer of cells with chondrogenic (cartilage-forming) potential. The chondrogenic cells undergo division and differentiate into chondroblasts.
