Briefly, osteoarthritis happens when the cartilage that cushions the ends of bones in your joints gradually deteriorates. Cartilage is a firm, slippery tissue that permits nearly frictionless joint motion. In osteoarthritis, the slick surface of the cartilage becomes rough. Eventually, if the cartilage wears down completely, you may be left with bone rubbing on bone. Factors that may lead to osteoarthritis include:
  • Obesity
  • Repeated trauma or surgery to the joint structures
  • Abnormal joints at birth (congenital abnormalities)
  • Gout
  • Rheumatoid arthritis
  • Diabetes
  • Other hormone disorders
