Study Notes
Osteoarthritis & Rheumatoid Arthritis
- Osteoarthritis (OA) is a progressive degenerative joint disease
- Most common sites affected include hips, knees, spine, and hands
- OA commonly occurs after age 40
- Risk factors include age, obesity, trauma to joints, and genetic factors
- OA can be caused by multiple factors, not just a single cause
- Rheumatoid Arthritis (RA) is a systemic autoimmune disease, meaning the immune system attacks healthy tissues
- RA commonly affects the synovial joints, leading to inflammation and pain
- RA targets the connective tissue in synovial joints.
- RA onset can be gradual or sudden.
Synovial Joint Structure
- Synovial joints account for about half of all body joints
- Cartilage cushions and reduces friction in the joint
- Cartilage degrades over time, leading to wear and tear
- Synovial membranes produce fluid that nourishes the cartilage and reduces friction
- The structure of the synovial joint includes bones, cartilage, synovial membrane, synovial fluid, and joint capsule
- OA changes the composition and quantity of synovial fluid
- The joint capsule provides stability to the joint
- Subchondral bone supports cartilage and absorbs movement impact
- Over time OA leads to reduced ability to absorb impact shock
- Bone spurs (osteophytes) may develop
- Cartilage degradation can lead to bone-on-bone contact and pain
Clinical Manifestations of OA
- Pain - affects quality of life, particularly worse in the morning. Symptoms resolve within 30 minutes
- Stiffness - noticeable especially in the morning. Can last longer in RA
- Crepitations - grating sensation arising from the cartilage surfaces.
- OA can be unilateral
- Pain and inflammation is a sign of progressive OA
Early Changes in OA
- Wide space normally present in the cartilage
- The cartilage structure is significantly damaged or eroded in the early stages of OA
- Synovium becomes inflamed
- Cartilage splits and erodes
Later Changes in OA
- Joint space narrowing due to cartilage loss
- Bone spurs (osteophytes) form at the edges of the joints
- Subchondral bone cysts develop underneath the cartilage
- Loss of cartilage- leads to bone-on-bone contact and pain
- Increased thickness of the subchondral bone
Clinical Manifestations of RA
- Morning stiffness for more than 30 minutes
- Symmetrical involvement (joints affected on both sides of the body)
- Can affect a range of ages and is commonly found in people between the ages of 30 and 50
- Other symptoms include pain, inflammation, nodules, fatigue, and fever with anorexia
- Hand pain is a common symptom in early stages of RA
Pathophysiology of RA
- A chronic autoimmune disease (body attacks healthy joint tissues)
- Inflammation of synovial joints are a common factor for RA.
- Inflammatory response is a response that occurs in early RA stages.
- Formation of pannus (inflamed synovial tissue)
- Disrupts joint structure
- Pannus degrades cartilage and bone
- Leads to joint damage and reduced mobility
Treatment of OA & RA
- OA treatment: Primarily focuses on pain management and symptom relief. Non-pharmacological therapies are recommended as the first line of intervention: rest and exercise, physiotherapy,
- RA treatment: Aims to suppress the immune response and slow down joint damage. Disease-modifying anti-rheumatic drugs (DMARDs) are a critical part of treatment, often used in combination with other therapies such as NSAIDs.
Evaluation of OA & RA
- Physical and Neurological Exam; specific symptoms are identified at the site of pain
- Imaging like x-rays is important for diagnosis of early OA
- Specific blood and joint fluid tests are crucial for determining RA vs OA
- The analysis of synovial fluid is critical for confirming OA diagnosis.
