The hip joint is the largest ball-and-socket joint in the body, and is surrounded by a tough, fibrous sleeve called the capsule, which helps to hold the bones together. The capsule is lined by the synovium, which produces a fluid (synovial fluid) that nourishes the 'shock-absorber' cartilage and lubricates the joint. With ageing , there is a lot of natural wear and tear so the cartilage becomes thinner. Damage to the cartilage can result in inflammation of the hip joint and pain . In certain circumstances, if the patient is in persistent pain, and medical treatment isn’t helping enough, the damaged joint might need to be replaced by an artificial joint.
Just the same, cortisone shots are commonly used--and often are successful--in helping to relieve arthritis symptoms temporarily. Some patients are able to use them to get enough pain relief to hold off joint replacement surgery for months or even years. Cortisone shots are a treatment for pain; they do not alter the course of arthritis and they do not cure the condition. In general, they are more commonly used for arthritis of other joints than they are for arthritis of the hip joint.
