While age is a risk factor, osteoarthritis isn't an inevitable part of aging. Obesity may lead to osteoarthritis of the knees. People with joint injuries due to sports, work-related activity or accidents may be at increased risk. Genetics usually plays a role in the development of osteoarthritis in the hands. Some people may be born with defective cartilage or with slight defects which may cause early cartilage breakdown in the joints as they age.
Physicians make a diagnosis based on a physical exam and history of symptoms.
X-rays are used to confirm the diagnosis. Treatment focuses on decreasing pain and improving joint movement. Consult your physician for appropriate diagnosis and treatment.
