Osteoarthritis is the most common form of degenerative arthritis; it occurs commonly in the joints which weight bear causing them to become painful resulting in limitations in movement and function.
The joints which can be affected are the knees, hips and feet specifically the big toe along with joints which are used a lot in daily life such as the hands, back and neck.
‘Around a third of people aged 45 years and over in the UK, a total of 8.75 million people, have sought treatment for osteoarthritis’ (Arthritis research, UK).
In the synovial joints such as the hip, knee, toes, fingers and wrists the structure of these joints allows movement of two adjoining bones.
At each end of these bones is a covering of articular hyaline cartilage which has a smooth slippery surface, this allows the bones to move against each other almost without friction.
The joint is surrounded by a synovial membrane (the synovium), which secretes synovial fluid into the joint cavity nourishing the cartilage and lubricating the joint. There is also a fibrous capsule supported by ligaments which holds the joint in place and stops the bones moving too far. The tendons anchor the muscles to the bone, the joint is also supplied with nerves and blood vessels.
