osteoarthritis quiz 3 Flashcards
what is osteoarthritis
degenerative joint disease causing breakdown of cartilage in joints, leading to joint pain & stiffness
Etiology of OA
unknown
Risk factor of OA
age genetics higher in female obesity joint instability trauma hormonal factors
what happens to the cartilage of OA
Smooth cartilage softens, swells–frays,ulcerates&wears
• Looses elasticity
• Overtime pieces wear away transmitted to bone, bone on bone
What are the pain c/o with OA
Aysemetrical pain is worse after use pain in worse after increase in activity or inactivity AM stiffness only <30 mins Slow on set
What are the systemic findings with OA
No systemic findings
Physical findings with OA
antalgic gait
crepitis in joints, with redness or tenderness
decrease ROM
What types of nodules acan be found with OA
Heberdens with women PIP
Bouchards DIP
OA in the hips main physical finding
Pelvic flexion sign
flex hip and pelvis will tilt upward and contralateral leg will raise off the table
OA of the Knee presents
Chronic& slowly progressive pain w/ambulation is hallmark
Unilateral joint tenderness & pain w/movement sensation of grating or catching in the knee.
Pain when walking up or down stairs
Mild effusion w/quad atrophy
Physical findings of the knee joints with OA
Lateral instability:
joint space decreased, elongated medial/lateral collateral ligament
Physical findings of the feet with OA
pain and tenderness in the great toe an d hurts when wearing tight shoes or high heels
How is OA diagnosed
joint pain Osteophytes on xray no warmth 50 stiffness for 30 min crepitus w/active ROM
Xray show with OA
unequal loss of joint space
Osteophytes
Juxta-articula sclerosis -rubbing of the joints
juxta articular osteopina and soft tissue swelling
Labs for OA a CBC,ESR, SMA7 , RF should be
normal
xray with OA assist with
determine a base line and progression of the disease.
Clinical findings of the knee in a patient with OA include all of the following except: A. coarse crepitus. B. joint effusion. C. warm joint. D. knee often locks or a pop is heard

A. wrists
B. elbows
C. metacarpophalangeal joint
D. distal interphalangeal joint
Xray of OA of the knee often reveal:
