Osteoarthritis (OA) is a degenerative joint disease and is the most common form of arthritis. Joints are normally covered by a lining called cartilage. Osteoarthritis occurs when the cartilage is worn out and can result in pain in the hip joint.
This condition typically affects elderly patients. However, young patients can also get osteoarthritis early due to injury, obesity or other medical conditions such as hip dysplasia, rheumatoid arthritis and gout.
