Osteoarthritis

Osteoarthritis, the most common type of arthritis, is sometimes referred to as "degenerative" or "wear-and-tear" arthritis. In osteoarthritis, the cartilage covering the bone ends gradually wears away. At its most advanced stage, the joint cartilage is completely eroded - down to the bone. Degeneration of joint cartilage and changes in underlying bone and supporting tissues lead to pain, stiffness, movement problems and activity limitations. All joints may be affected by osteoarthritis, but it is often more painful in weight-bearing joints such as the hip, knee, or spine.

Rheumatoid Arthritis

Rheumatoid arthritis is a systemic disease that affects people of all ages, including children. In rheumatoid arthritis, the body's immune system produces a chemical that attacks and destroys the lining of the joint, the cartilage, and the joint surface itself. Consequently, swelling, pain, joint damage and loss of mobility occur - even if the joint isn't used. Rheumatoid arthritis often affects the wrist joints and the finger joints closest to the hand.

Trauma-Related Arthritis

Trauma-related arthritis occurs when the joint is injured -- for instance, in a fall or an auto accident.

Regardless of the type of arthritis, the disease can cause symptoms of joint pain, stiffness, limping, muscle weakness, limitation of motion and swelling. Pain is the main problem with advanced arthritis in any joint. Depending on the joint affected and the amount of damage, ordinary activities such as walking, putting on socks and shoes, getting in and out of cars, and climbing stairs may be difficult. As the condition worsens, symptoms worsen.

Healthy Hip Anatomy

The hip joint forms where the top of the thighbone (femur) meets the socket of the pelvic bone. The top of the femur is ball-shaped and fits snugly in the socket.

The bones of the hip joint are covered by cartilage that protects the bones while allowing easy motion. Surrounding the hip joint is the synovial lining, which produces a lubricant. Tough fibers, called ligaments, connect the bones of the joint and hold them in place, while adding strength and elasticity for movement. Muscles and tendons also play an important role in keeping the hip joint stable. When the cartilage wears away due to arthritis, people may experience chronic pain. It is important to visit a healthcare professional who may prescribe medications or recommend surgery or other treatment.
