Osteoarthritis is a joint disease that mostly affects cartilage. Cartilage is the slippery tissue that covers the ends of bones in a joint. Healthy cartilage allows bones to glide over each other. It also helps absorb shock of movement.
Having osteoporosis does not automatically mean that your bones will break, it just means it is more likely and that you have a âgreater risk of fractureâ. Thin, fragile bones in themselves are not painful but the broken bones that can result can cause pain and other problems.steoporosis occurs when the struts which make up the mesh-like structure within bones become thin, causing bones to become fragile and break easily, often following a minor bump or fall. These broken bones are often referred to as fragility fractures.
