Signs/Symptoms

Osteoarthritis can remain undetected until a significant portion of joint cartilage has worn away. Signs to look for include, but are not limited to:

Joint pain, tenderness, stiffness and locking
Joint swelling (bones around the joints may feel larger than normal)
Ligaments and muscles around a joint become weaker and stiffer
A cracking or grating sound when a joint is moved
Limited range of joint motion

The exact cause of OA is not yet known but causal factors include, but are not limited to:

Natural aging and wear and tear
Bleeding disorders that cause bleeding in the joint, such as hemophilia
Disorders that block the blood supply near a joint and lead to avascular necrosis
Other types of arthritis, such as chronic gout, pseudogout or rheumatoid arthritis
OA can develop within 10 years of a major joint injury. For example, a teenager who tears their ACL at age 15 could begin to develop OA as early as age 25 or 30

Risk Factors

Certain factors that increase the risk of developing OA include, but are not limited to:

Heredity
Being overweight
Joint injury
Repeated overuse of certain joints
Lack of physical activity
Nerve injury
Aging

Potential Complications

Other complications may arise from osteoarthritis. They include, but are not limited to:

Pain that causes stiffness and loss of movement ability
Muscle spasms and contractions in affected tendons
Fluid accumulation in the joint
Crackling noises in the joint
Hard bony enlargements, nodes, or bunions form around the joint
