Osteoarthritis (OA) & Rheumatoid Arthritis (RA) Flashcards
What type of disease is Osteoarthritis?
Degenerative wear and tear
Osteoarthritis is primarily due to the aging process and mechanical stress on joints.
What tissue is affected by Osteoarthritis?
Articular cartilage
The articular cartilage is the smooth, white tissue that covers the ends of bones where they come together to form joints.
Which joints are mostly affected by Osteoarthritis?
Mostly hips and knees
These are weight-bearing joints that endure significant stress.
At what age does Osteoarthritis commonly onset?
50 years +
Osteoarthritis typically begins to manifest in individuals over the age of 50.
Is Osteoarthritis symmetrical or asymmetrical?
Asymmetrical
Osteoarthritis often affects joints on one side of the body more than the other.
What radiology findings are associated with Osteoarthritis?
Osteophytes, narrowed joint space
Osteophytes are bone spurs that develop in response to joint degeneration.
What blood tests are typically abnormal in Osteoarthritis?
No abnormal findings
Osteoarthritis does not usually show changes in blood tests.
What type of disease is Rheumatoid Arthritis?
Autoimmune
Rheumatoid Arthritis occurs when the immune system mistakenly attacks the body’s own tissues.
What tissue is affected by Rheumatoid Arthritis?
Synovial membrane
The synovial membrane lines the joints and produces synovial fluid.
Which joints are affected by Rheumatoid Arthritis?
Any synovial joints
Rheumatoid Arthritis can affect joints throughout the body and tends to be systemic.
At what age does Rheumatoid Arthritis commonly onset?
30-50 years
The onset of Rheumatoid Arthritis typically occurs in middle adulthood.
Is Rheumatoid Arthritis symmetrical or asymmetrical?
Symmetrical / bilateral
Rheumatoid Arthritis generally affects the same joints on both sides of the body.
What radiology findings are associated with Rheumatoid Arthritis?
Bone erosions on x-ray
Bone erosions indicate joint damage due to inflammation.
What blood tests are typically abnormal in Rheumatoid Arthritis?
Raised ESR, CRP, rheumatoid factor
These tests indicate inflammation and the presence of autoimmune activity.
What is the onset pattern of Osteoarthritis (OA)?
Gradual onset with increasing pain over months or years
Which joints are primarily affected by Osteoarthritis?
Weight-bearing joints
What is the duration of morning stiffness in Osteoarthritis?
Less than 30 minutes
When is pain often worse in Osteoarthritis?
Often worse in the evening
What is a common physical change in joints due to Osteoarthritis?
Eventually the joints become deformed
What type of joint enlargement is seen in Osteoarthritis?
Enlarged joint in distal finger
Does Osteoarthritis present systemic symptoms?
No systemic symptoms
What is a key characteristic of Rheumatoid Arthritis (RA) regarding joint pain?
Bilateral joint pain affecting small joints (hands and feet mostly)
What is the duration of morning stiffness in Rheumatoid Arthritis?
More than one hour
What deformities can occur in Rheumatoid Arthritis?
Deformities occur, including ulnar deviation of digits and swan neck fingers
