What is Hip Joint Arthritis?
One of the most common causes of hip pain is hip joint arthritis. Arthritis is a medical condition, which is progressive in nature, i.e. this disease usually begins gradually and over the time gets worse. The meaning of arthritis is joint inflammation. Arthritis of the hip joint or any other area does not have a cure. Treatment of arthritis of hip joint comprises of alleviating the pain and other symptoms. The hip joint can be affected by different types of arthritis. Treatment depends on the type of arthritis of the hip joint.
Types of Hip Joint Arthritis
The types of arthritis which can affect a hip joint include:
- Rheumatoid arthritis.
- Ankylosing spondylitis.
- Psoriatic arthritis.
- Systemic lupus erythematosus.
Causes & Risk Factors of Hip Joint Arthritis
Hip Joint Osteoarthritis
Osteoarthritis is the commonest type of arthritis. The cause of osteoarthritis is wear and tear of the joints due to age, because of which it is often seen in older people than younger ones. The hip joint is made up of the femoral head, which is the ball-shaped end of the thigh bone. This fits into the acetabular socket, which is the hip socket. The hip joint is lined with a smooth cartilage, which enables the joint to move easily. When there is any wearing off this smooth cartilage then the rough surfaces of the hip joint rub against each other resulting in pain. Gradually, osteoarthritis can degenerate the hip joint and even cause permanent damage to it.
Risk Factors of Hip Joint Osteoarthritis
- Problems with the structure of the hip joint, such as femoroacetabular impingement and hip dysplasia.
- Increased aged individuals are at an increased risk for hip joint osteoarthritis.
- Obesity or being overweight increases the risk of having hip joint osteoarthritis.
- Previous injury or damage to the hip increases the risk of developing hip joint osteoarthritis. Osteoarthritis can also occur in individuals who do not have these risk factors.
Rheumatoid Arthritis of the Hip Joint
Rheumatoid arthritis is a systemic medical condition. It affects the entire body along with the hip joint. The cause of inflammation in rheumatoid arthritis is an immune system response instead of wear and tear, as seen in osteoarthritis. A special capsule surrounds the hip joint, which protects it. This capsule contains a special lining known as synovial lining, which is filled with joint fluid that acts a lubricant to help the hip joint move smoothly. In rheumatoid arthritis of hip joint, there is swelling of the synovial lining resulting in pain and swelling of the hip joint. As time goes on, there is deterioration of the cartilage and bone from rheumatoid arthritis.
Rheumatoid arthritis can affect people of all ages. If it affects children, then it is known as juvenile rheumatoid arthritis. Women suffer more from rheumatoid arthritis than men. Rheumatoid arthritis often affects both the hip joints at the same time along with other joints. Patient also experiences fatigue and general weakness from rheumatoid arthritis.
Hip Joint Arthritis Caused Due to Ankylosing Spondylitis
Ankylosing spondylitis is a condition where there is chronic inflammation of the spine and the sacroiliac joint. In some cases, this can also cause inflammation in the hip joint. People of all ages can be affected from ankylosing spondylitis including children. This condition usually starts in individuals who are aged between 18 and 35 years. Men tend to suffer more from ankylosing spondylitis than women.
Patients suffering from ankylosing spondylitis will commonly experience flare ups of this condition where there is worsening of the symptoms followed by periods of remission where the patient has mild or no symptoms.
Hip Joint Arthritis Caused Due to Systemic Lupus Erythematosus
Systemic lupus erythematosus (SLE) is a systemic autoimmune disorder, which can affect any region of the body, including the hip joint. SLE affecting the joint will cause damage and inflammation to the joint. Lupus can affect individuals of any ages; however, most commonly affects women who are between 16 to 35 years of age.
Hip Joint Arthritis Caused Due to Psoriatic Arthritis
Psoriatic arthritis occurs in relation with psoriasis, which is a skin condition. This condition can affect any type of joint including the hip joint. In psoriatic arthritis, patient experiences joint pain, stiffness and swelling. It is common to develop the skin condition (psoriasis) first before the development of psoriatic arthritis; however, some people can have psoriatic arthritis before the appearance of the skin condition.

- Arthritis tends to occur in bouts or flares with periods of remission; however, some patients may have a constant level of pain without any flare ups.
Diagnosis of Hip Joint Arthritis
- Patient's medical history and physical examination are done where the range of motion of the hip joint is tested along with seeing if the patient walks with a limp.
- X-rays are done to find out if there are any abnormalities in the hip joint.
- Blood tests are done to look for antibodies, which are present in a specific type of hip joint arthritis, such as seen in lupus and rheumatoid arthritis.
