OA Flashcards
What is Oligoartritis?
Inflammation affecting 2 to 4 joints.
Oligoartritis can also present as monoartritis.
Differentiate between Monoarthritis, Oligoarthritis, and Polyarthritis.
- Monoarthritis: only 1 joint affected
- Oligoarthritis: 2 to 4 joints affected
- Polyarthritis: 5 or more joints affected.
What is the onset time frame for acute conditions?
Onset in hours or days.
What is the onset time frame for chronic conditions?
Onset of weeks to months.
Define additive vs migratory pain.
- Additive: pain increases over time, affecting more joints
- Migratory: pain moves from one joint to another.
What does persistent pain mean?
Pain that remains constant.
What does recurrent pain mean?
Pain that occurs in episodes or crises.
What is the difference between proximal and distal joints?
- Proximal: shoulder, elbow, knees
- Distal: small joints of the hands.
What is the classic presentation of polyarthritis?
Additive, asymmetric, predominance in upper joints, more common in women.
What type of pain is characteristic of inflammatory lumbar pain?
Spondylitis, worsens in the morning with stiffness.
What are systemic manifestations?
Involvement of other organs, such as in lupus.
In osteoarthritis (OA), which joints are typically spared?
Wrist (except the base of the thumb) and metacarpophalangeal joints.
Which is the most common non-inflammatory joint disease?
Osteoarthritis (OA).
Which is the most common inflammatory joint disease?
Rheumatoid arthritis (AR).
List the main general characteristics of osteoarthritis.
- Joint pain
- Stiffness
- Deformity
- Loss of function
- Chronic disability.
What are common manifestations of osteoarthritis?
- Joint pain
- Functional limitation
- Crepitus
- Occasional joint effusion
- Inflammation.
What is the primary cause of osteoarthritis?
Degeneration and progressive loss of hyaline cartilage.
What are the common sites affected by osteoarthritis?
- Knees
- Hands
- Hips.
What factors can contribute to knee osteoarthritis?
- Age
- Female gender
- Physical activity
- Quadriceps strength.
What is the significance of joint space narrowing in osteoarthritis?
It indicates asymmetrical changes and sclerosis.
What diagnostic method is primarily used for osteoarthritis?
Clinical evaluation.
What are the imaging characteristics of osteoarthritis?
- Subchondral sclerosis
- Osteophyte formation
- Radiolucent erosions.
What is the role of patient education in osteoarthritis treatment?
Educate patients compassionately about managing their condition.
What is the recommended non-pharmacological treatment for osteoarthritis?
Exercise and weight loss.
What are the roles of rheumatologists and orthopedic surgeons in osteoarthritis?
- Rheumatologists: educate patients, rule out other causes
- Orthopedic surgeons: perform surgery.
True or False: Radiological studies predict the response to non-surgical treatment in osteoarthritis.
False.
Fill in the blank: Osteoarthritis is characterized by the degradation of _______.
