Arthritis Flashcards
OA or RA
Insidious onset
Both
OA or RA
Morning pain more than 30 minutes
RA
OA vs RA
Palpation of affected tissues feels spongy
RA
OA or RA
Symptoms on both sides (symmetrical)
RA
OA or RA
Presence of nodules
RA
OA or RA
Wearing away of joint cartilage
Both
OA or RA
Immune system attacking synovium
RA
OA or RA
Palpation feels narrowing of joint space and bony spurs
OA
arthritis
group of diseases (100+) characterized by inflammation in joints and other areas of the body
osteoarthritis
wear and tear arthritis; body’s failed attempt to repair damaged joint tissues from aging or injury
Most common type of arthritis (general)
osteoarthritis (OA)
arthro + itis
joint + inflammation
consequences of arthritis
redness, swelling, pain
can lead to damage, loss of function, disability
arthritis = chronic or acute
chronic
osteoarthritis
progressive disease of whole joint leading to breakdown of cartilage and underlying bone
osteoarthritis pathology
pathology:
equilibrium of chemical reactions in articular cartilage disrupted
collagen in cartilage becomes disorganized, loses elasticity
cartilage cracks and fissures, articular surface erodes
formation of bony spurs
osteoarthritis tissue types affected
whole joint: ARTICULAR CARTILAGE LOSS, bone, soft tissue, ligament laxity, muscle atrophy, synovium, increased volume of synovial fluid with reduced viscosity, menisci
osteophyte
boney spurs
Primary vs Secondary OA
Primary = aging (most common, 55-60 yrs)
Secondary = specific cause, such as trauma or injury, usually develops earlier in life (45-50 yrs)
Diagnostic tool and treatment guide for OA
Radiography
Note: early may not reflect symptoms; later may appear worse than symptoms
Kellgren - Lawrence classification tool
Kellgren-Lawrence grade 1
Grade 1 DOUBTFUL narrowing of joint space possible osteophyte formation no sclerosis no bone end deformity
Kellgren-Lawrence grade 2
Grade 2 possible narrowing of joint space DEFINITE osteophyte formation no sclerosis no bone end deformity
Kellgren-Lawrence grade 3
Grade 3 DEFINITE narrowing of joint space moderate osteophyte formation SOME sclerosis possible deformity of bone ends
Kellgren-Lawrence grade 4
grade 4 = greatest severity SEVERE narrowing of joint space LARGE osteophyte formation MARKED sclerosis DEFINITE deformity of bone ends
