Osteoarthritis of the hip is a type of arthritis that causes inflammation of the joints of the hips, although osteoarthritis can occur in any of the body's joints, notes WebMD. Joint inflammation results in swelling and pain, limiting mobility. Osteoarthritis is also known as age-related arthritis or degenerative joint disease, since people tend to develop it with aging. Osteoarthritis is the most common form of arthritis.
Symptoms of osteoarthritis in the hip include joint stiffness when getting out of bed or sitting for long periods of time, a crunching feel or sound when moving the hip, and swelling, tenderness and pain in the hip joint, reports WebMD. Limited mobility when performing routine activities may also indicate osteoarthritis.
Osteoarthritis in the hip is known as primary osteoarthritis, notes WebMD. Patients with the condition often find it difficult to walk due to the condition's dull aches or sharp, stabbing pains. The condition usually develops slowly over the course of many years.
Although the exact causes of osteoarthritis in the hip are not fully understood, being overweight, older and experiencing previous joint injuries contribute to the disease's formation, advises WebMD. In some cases of osteoarthritis of the hip, the joints are formed improperly or a genetic disorder affects the cartilage, causing the condition.
