degenerative disease (OA) Flashcards
What joint changes would you expect in degenerative disease
small cracks in the cartilage = early
fibrillation
complete wearing away of the cartilage
eburnation = surface becomes “polished”
what would you expect to see on X-ray
LOSS
Loss of joint space
Osteophytes
Subchondral sclerosis
Subchondral cysts
what is osteoarthritis (OA)
articular cartilage thinning or loss, commonly called wear and tear in the joints
what are the two types of osteoarthritis
idiopathic
secondary
what are the risk factors of osteoarthritis
old age female obesity previous injury muscle weakness proprioceptive deficits acromegaly joint inflammation cyrstal deposition in the cartilage
what are the symptoms of osteoarthritis
pain: worse on activity, better with rest
stiffness: morning, <30mins
crepitus
joint swelling, tenderness, and effusion
bony enlargements genu varus or valgus deformities
bakers cyst
what is the treatment of osteoarthritis
physio weight loss exercise surgery pain meds - tricyclis NSAIDs intra-articular steroids
what are the investigations of osteoarthritis,what would you expect to see
X-ray = LOSS
o Loss of joint space
o Osteophytes
o Sclerosis
o Subchondral cysts
what causes loss of joint space
cartilage loss
what causes subchondral sclerosis
eburnation
what causes subchondral cysts
synovial fluid accumulation
what causes osteophytes
disorganised bone remodelling
