Biomechanics And Kinesiology - Mechanics Of Joint Function, Tendons And Ligaments

Question 1

Cartilage fails when

Answer 1

• repetitive matrix stressing causes loosening of collagen network
• high contact pressures between joint surfaces
• joint surface incongruity affects load distribution over joint surfaces and increases stress

Question 2

Osteoarthritis

Answer 2

• chronic degenerative disorder related to ageing

Question 3

Rheumatoid arthritis

Answer 3

• chronic systemic inflammatory disorder primarily affecting joints, but also lungs, kidneys and heart

Question 4

Gout

Answer 4

• recurrent attacks of acute inflammatory arthritis

Question 5

Tendons

Answer 5

• attach muscle to bone

- transmit tensile loads from muscle to bone

Question 6

Ligaments

Answer 6
