Answer 6

synovitis

Question 7

vertical clefts in the cartilage

Answer 7

fissures

Question 8

a disorder that occurs in the synovial joints and results in progressive degeneration of the articular cartilage and subchondral bone

Answer 8

osteoarthritis

Question 9

what kind of joints are affected by osteoarthritis

Answer 9

synovial

Question 10

age, genetics, nutrition, hormones, bone density, and inflammation are what kind of factors to osteoarthritis

Answer 10

systemic

Question 11

excessive/reduced joint use, muscle weakness, joint deformity, pre-existing articular disease, and immobilization are what kind of factors to osteoarthritis

Answer 11

local

Question 12

gender-age connection, obesity, altered biomechanics, and acute trauma are what kind of factors to osteoarthritis

Answer 12

extrinsic

Question 13

when are men more likely affected by osteoarthritis

Answer 13

younger age

Question 14

when are women more likely affected by osteoarthritis

Answer 14

middle age and older

Question 15

abnormal stress on cartilage leads to more susceptibility to what kind of disruption

Answer 15

mechanical disruption

Question 16

as cartilage wears, what happens to the underlying bone

Answer 16

becomes fissured and thickened

Question 17

stage of cartilage degeneration wherein fine flakes of superficial cartilage become loosened and flake off

Answer 17

fibrillation

Question 18

what appears during cartilage degeneration that eventually run through the full thickness of the cartilage, and potentially to the bone

Answer 18

fissures

Question 19

during cartilage degeneration, synovial fluid may be forced into fissures that appear in the bone’s surface, producing cysts

Answer 19

synovitis

Question 20

how does osteoarthritis present when first developing

Answer 20

nearly asymptomatic

Question 21

abnormal ROM/biomechanics result in what two problems

Answer 21

decreased joint nutrition, repetitive abnormal stress to joint surface

Question 22

stage of osteoarthritis: no inflammation or pain, repeated stresses to load bearing portions of articular cartilage, may last years

Answer 22

mild

Question 23

stage of osteoarthritis: more pronounced breakdown of articular surfaces, progression leads to fibrillation, synovitis, fissures

Answer 23

moderate

Question 24

stage of osteoarthritis: increased inflammation, capsule and ligament laxity, fissures extend to the subchondral bone, eburnation, pain, osteophytes, lipping/spurring

Answer 24

severe

Question 25

how do osteophytes affect ROM

Answer 25

severe restriction, may also affect surrounding tissues

Question 26

how do altered joint capsules affect ROM

Answer 26

chronic inflammation can lead to thickening, adhesions, contracture

Question 27

a method of classifying the severity of knee osteoarthritis from grade 0-4

Answer 27

kellgren and lawrence system

Question 28

grade of kellgren and lawrence system: no radiographic features of osteoarthritis are present

Answer 28

0

Question 29

grade of kellgren and lawrence system: doubtful joint space narrowing and possible osteophytic lipping

Answer 29

1

Question 30

grade of kellgren and lawrence system: definite osteophytes and possible joint space narrowing on anteroposterior weight-bearing

Answer 30

2

Question 31

grade of kellgren and lawrence system: multiple osteophytes, definite joint space narrowing, sclerosis, possible bony deformity

Answer 31

3

Question 32

grade of kellgren and lawrence system: large osteophytes, marked joint space narrowing, severe sclerosis, definite bone deformity

Answer 32

4

Question 33

common osteoarthritis location: stiffness, radicular or nonradicular pain, osteophytes may cause neurovascular compression

Answer 33

cervical spine

Question 34

common osteoarthritis location: lower back pain and stiffness, muscle spasm, limited ROM, radicular symptoms, spinal stenosis

Answer 34

lumbar spine

Question 35

common osteoarthritis location: most common in older men, insidious onset, localized to the groin, reduced ROM, leg may be held in external rotation with hip flexed and adducted, limp or shuffling gait

Answer 35

hip

Question 36

common osteoarthritis location: localized discomfort with pain or motion, limited ROM, crepitus, quadriceps atrophy, joint instability, genu varus/valgus, joint effusion

Answer 36

knee

Question 37

common osteoarthritis location: tenderness at the base of the thumb, squared appearance to joint

Answer 37

cmc1

Question 38

common osteoarthritis location: occurs more frequently in women, usually involves multiple joints, lateral flexor deviation of joint, pain and discomfort after use, spur formation of joint margins

Answer 38

pips and dips

Question 39

osteoarthritis in PIPs

Answer 39

bouchard's nodes

Question 40

osteoarthritis in DIPs

Answer 40

heberden's nodes
