Osteoarthritis (OA) develops when the protective covering of cartilage that covers the end of each bone in a joint starts to wear away. Instead of your bones gliding smoothly over each other, damaged or missing cartilage causes friction. Pain and swelling ensues, and bits of bone and cartilage may chip off and float inside the joint. In its latest stages, osteoarthritis can cause bone to rub directly against bone, causing more pain and joint damage.
