Cartilage is made of collagen and protein
Joint Cartilage is made of extracellular matrix and chondrocytes
Extracellular matrix contains type 2, 4, and 6 collagens as well as aggrecan
primarily proteoglycans
Type 2 collagen is responsible for protecting the ends of bone within a joint
Aggrecan proteoglycan is mainly retaining water molecules, allowing resistance to
responsible for affects of strenuous use of the joint
Chondrocytes within joint cartilage the strength and resistance to loading
is responsible for
, What is the pathophysiology of when cartilage becomes damaged it starts to
osteoarthritis? lose elasticity, making it more susceptible to
injury. With increasing stress and wear the bone
starts to become affected causing thickening of
bone and formation of bone spurs and
osteophytes. Abnormal bone formations can
break loose with cartilage fragments and float
within joint space. Debris cause synovium to
mount and inflammatory response to break down
cartilaginous debris.
What does the inflammatory the breakdown of remaining healthy cartilage,
response during degeneration of leading to further degeneration
cartilage increase?
Osteoarthritis symptoms: pain that is exacerbated with activity and better
with rest (early dz), stiffness, swelling, pain and
stiffness worse in the morning (no more than 30
min), pain worse with prolong inactivity or
weather changes
Hip osteoarthritis symptoms: pain in low back and groin, limping and knee pain
from compensation
Knee osteoarthritis symptoms: locking, cracking, grinding, "give out" feeling,
increasing pain with ascending and descending
stairs
Finger osteoarthritis symptoms: swelling, nodules, stiffness, difficulty gripping
