The hip joint
The hip joint is the second largest joint. The thigh bone (femur) and the pelvis form the bony joint partners.
The acetabulum of the pelvis and the round femoral head of the thigh bone, which is like a ball in the acetabulum, are covered with a smooth layer of cartilage.
As an elastic tissue, the articular cartilage enables low-friction movement. The hip joint is covered by an extremely strong joint capsule. The joint gets stability through strong ligaments, a joint capsule and the surrounding muscles.
There are various disorders of the hip joint, such as congenital changes of the joint, flattened acetabulum (hip dysplasia), or hip necrosis. Hip arthrosis is a common condition.
