Q

What is osteoarthritis and who might it affect?

A
  • = Degenerative joint disorder in which there is progressive loss of hyaline cartilage and bone remodelling.
  • Typically affects people >50y. “Wear and tear”
  • Risk factors: Age, obesity, previous injury, joint abnormality, haemachromatosis.
