Osteoarthritis (OA) and (rheumatoid) arthritis (RA) both affect the joints, but they are not the same, and understanding the difference can help guide treatment and rehabilitation.
OA is a mechanical, degenerative condition where the joint structures slowly wear down over time.
It happens when:
The cartilage between bones breaks down due to friction.
The joint produces excess synovial fluid, causing swelling.
Tendons and ligaments lose elasticity and mobility.
OA is most often linked to aging, previous injuries, repetitive stress, or overworked joints.
Symptoms include pain, stiffness, and reduced mobility, especially after activity or first thing in the morning.
RA is a chronic autoimmune disease, meaning the immune system mistakenly attacks the body’s own joint tissues.
It mainly affects:
The synovial membrane.
Tendons and ligaments.
Multiple joints on both sides of the body.
RA leads to inflammation, swelling, pain, and sometimes a burning sensation.
Unlike OA, RA can affect people of any age, and symptoms can flare up unpredictably.
Both OA and RA can impact function, but the management approach differs. Movement, strengthening, joint education, and load management are essential for both, but RA also requires medical treatment to control inflammation.
Consult an accredited Biokineticist to receive assistance in the form of rehabilitative exercises and patient education to help manage recovery from this condition and assist with activities of daily living.
