Common causes of hip osteoarthritis include:

• Genetics; chances of developing the condition are increased if there is a family history of arthritis
• Poor blood supply to the bones, either temporary or permanent
• Rheumatoid arthritis or other inflammatory joint diseases
• Previous injuries to the hip, such as hip dislocation or fractures
• Infections
• Abnormality of the hip joint, such as hip dysplasia

Common symptoms of hip osteoarthritis include:

• Initial signs of hip osteoarthritis include pain in the groin area or front of the thighs and a feeling of stiffness during movement of the hip joint. Symptoms worsen during physical activity and decrease while resting.
• In cases where there is severe pain, it could lead to muscle deterioration as the muscles around the hip joint weaken through inactivity.
• When there is inflammation of the hip joint, bone spurs around the hip joint may occur. Furthermore, if the cartilage is completely worn away, this may cause extreme pain as the bones grind together. The leg may even shorten because of this.
