The hip joint is also one of our most flexible joints and with the exception of the shoulder, the hip joint allows for a greater range of motion than all other joints in the body. The hip joint is a ball-and-socket synovial joint formed between the os coxa (hip bone) and the femur. A round, cup-shaped structure on the os coxa known as the acetabulum forms the socket for the hip joint. The rounded head of the femur forms the ball of the joint.
A thin tissue called the synovial membrane surrounds the hip joint. In a healthy functioning hip this membrane produces a small amount of fluid that lubricates the cartilage and eliminates almost all friction during movement of the joint. Problems and hip pain occur when the joint surface wears out which causes the bone ends to rub painfully on each other.
Due to the structure of the hip joint the articular cartilage is prone to degeneration through injury, overuse and ageing.
Other common hip problems involve dislocation, tears and injury to the ligaments that surround and support the joint.
Common surgical procedures are available to repair the joint, restore function and reduce pain. Dr.Aditya Khemka specialises in Hip Replacement (hip arthroplasty) in which he utilises the Direct Anterior Approach as well as the Posterior Approach, Hip Arthroscopy and Minimally Invasive Hip Surgery.
