Osteoarthritis usually develops slowly and worsens over time, leading to symptoms such as:
The pain tends to be worse when you move the joint or at the end of the day.
Stiffness is commonly experienced first thing in the morning or after a long period of inactivity such as a car ride.
You might not be able to move your joint through its full range of motion.
This might be caused by soft tissue inflammation around the joint.
Joints may feel like they are grating or creaking as the bones rub against each other.
The exact cause is not known, but several things are thought to increase the risk factors:
The risk of developing OA increases with age.
Women are more likely to develop OA than men.
Extra weight puts more stress on joints.
Repetitive stress on a joint or an injury can damage a joint and increases the risk of OA in that joint.
Some people can inherit a tendency to develop OA.
Some people are born with abnormalities and develop malformed joints or defective cartilage.
Sometimes OA is a result of damage from a different kind of disease. Other factors such as the weather and diet may affect the symptoms of OA but aren’t a direct cause of it.
