Versus Arthritis explains that a joint is where two or more bones meet, such as in the fingers, knees, and shoulders, and they hold bones in place and allow them to move freely within limits.
The most common type of arthritis is osteoarthritis. It is estimated that around 8.75 million people in the UK have seen a doctor about osteoarthritis, notes the charity.
Osteoarthritis initially affects the smooth cartilage lining of the joint. This makes movement more difficult than usual, leading to pain and stiffness.
“Sometimes, the early stages of osteoarthritis can happen without causing much pain or trouble. However, it can lead to damage inside a joint, as well as pain and stiffness,” it says.
