Why does articular cartilage thin over time? - Decreased fluid and collagen
What does friction between articulating surfaces cause in a patient? - - Pain
- Limited ROM
Inflammation of a joint - Arthritis
______ Americans are diagnosed with arthritis - 46.4 million
What are the 2 reasons for the growing # of cases of arthritis? - - Aging
- Obesity
What is arthritis treated with? - Exercise
______ is swollen inflamed synovial membrane & erosion. - Rheumatoid Arthritis (RA)
_____: bone ends rub together & thinned cartilage - Osteoarthritis (OA)
What happens to collagen fibers as we age? - Shorten, lose elasticity
What kind of cartilage is in synovial joints? - Articular cartilage
What happens to synovial joints as we age? - - Cushion loss
- Reduced capillary blood supply to synovial membrane = less fluid = stiffness, immobility
,What happens to the spine as we age? - Stiffness and reduced flexibility
OA is _____________ (wear and tear; overuse) - Degenerative
______% show OA evidence on x-ray by age ______ , but symptoms come later - - 90%
- by age 40 (may start before age 40)
Bone-on-bone is _____________ ______________ of articular cartilage. - Complete degradation
What symptoms does bone-on-bone cause in a patient? - - Pain
- Inflammation
- Weak ligaments
- Atrophy
Bone-on-bone causes the bone to thicken, which causes _______ _______ - Bone spurs
Bone-on-bone reduces ________ ________ - Physical activity (PA)
What are the 6 OA risk factors? - - Obesity
- Aging
- Diabetes
- Joint trauma
- Overuse
- CAI
What are the 5 symptoms of OA? - - Crackling sounds in joints
- Loss of joint ROM
, - Unilateral
- Joint pain (more with activity, less with rest; pain experienced in waves)
- Stiffness (~30 min after period of immobility)
What are the goals when treating OA? - - Reduce symptoms
