Osteoarthritis of the hip has no single specific cause, but there are certain factors that may make you more likely to develop the disease, including increasing age, family history of osteoarthritis, previous injury to the hip joint, obesity and improper formation of the hip joint at birth- a condition known as developmental dysplasia of the hip. Unfortunately, even if you do not have any of the risk factors listed above, you can still develop osteoarthritis of the hip.
The most common symptom of hip osteoarthritis is pain around the hip joint. Usually, the pain develops slowly and worsens over time, although sudden onset is also possible. Pain and stiffness may be worse in the morning, or after sitting or resting for a while. Over time, painful symptoms may occur more frequently, including during rest or at night. Additional symptoms may include “Locking” or “sticking” of the joint, and a grinding noise (crepitus) during movement caused by loose fragments of cartilage and other tissue interfering with the smooth motion of the hip, decreased range of motion in the hip that affects the ability to walk and may cause a limp and increased joint pain with rainy weather.
