eing overweight increases the risky Fractures or other joint
injuries can lead to osteoarthritis later in life
y Long-term overuse at work or in sports can lead to
osteoarthritis
y Old age; autoimmune response
Deterioration and changes to the articular cartilage
formation of new bone at the surfaces of the joints
(weight-bearing joints, which include the spine, hip, knee,
andankle)
joint surface thins and the cartilage softens
disruption in the integrity of the surface and development
of
clefts
formation of ulcers that extend deep into the bones
cartilage becomes hypocellular or lacks the chondrocytes to
help rebuild and maintain integrity
bone remodeling and hypertrophy
Appositional bone growth occurs in the subchondral
region,leading to the bony sclerosis seen radiographically
Growth of cartilage and bone around the joints restricts the
movement of the joints causing pain and disability
