Osteoarthritis Flashcards
What is OA
“wear and tear”
cartilage covering the joint wears out, develops cracks, fissures, and eventually complete full thickness cartilage loss
What joints does OA affect the most
DIP, PIP, base of thumb (CMC),
Where do Heberden’s and Bouchard’s nodes occur
Heberden: DIP
Bouchard: PIP
Radiographic features of OA
joint space narrowing marginal osteophytes subchondral cysts bony sclerosis malalignment
Clinical features of OA
pain related to use
pain gets worse during the day
minimal morning stiffness
ROM decreases
What labs do you order for OA
None really; can get CRP or ESR but if there is anything else going on in the body these will be elevated
OA risk factors
old age female obesity hereditary trauma neuro dysfunction metabolic disorder
Tx/Management of OA
modalities (heat) exercises bracing acetaminophen topical NSAIDs NSAIDs tramadol/opioid analgesics corticosteroid injections surgery
Should a pt with knee OA wear a brace all the time
No only use for short periods of time, should go to PT to strengthen muscles around the joint so brace isn’t needed
Should pts get arthroscopy
not necessarily; many pts have meniscal damage without any problems and do unnecessary surgeries
First line tx for OA
muscle strengthening weight loss acetaminophen local heat/cold maybe glucosamine/chondroitin
What is osteoarthritis of the hip aka
DJD (degenerative joint disease)
What are DJD symptoms
gradual onset pain
pain with weight bearing
night pain
What DJD signs
Trendelenberg lurch/sign
hyperlordosis/flexion contracture
loss ROM
limb shortening
What compartment can OA involve
Medial, lateral, or patellofemoral
