    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
