Physical Therapist’s Guide to Osteoarthritis

Your bones are connected at joints and a rubbery substance called cartilage coats the bones at these joints which helps to reduce friction when you walk and move around. In addition another protective oily substance (called synovial fluid) is also contained within the joint, and it’s job is also to help ease movement. When these protective coverings break down, the bones begin to rub together during movement which causes pain – this is osteoarthritis.
