The symptoms of osteoarthritis include, pain within the joint (especially after physical activity or long periods of inactivity, such as sitting in the car during a long trip), stiffness in the joint, creaking or grating sounds, muscle weakness, joint deformity, swelling, and limited movement, particularly in the mornings.
The most common location for osteoarthritis to occur is the knee. Osteoarthritis usually occurs in one or more joints in the body, where the cartilage has become damaged, either through ‘wear and tear’ as we get older, or sustained in an injury. Over time, pain and damage increases, and the joint may become more unstable, due to ligaments stretching and the muscles becoming weaker. Or, the joint may become more rigid, and the full range of motion lost, due to damage, and possible bony growths, which can cause the joints to become deformed. This commonly occurs in the fingers, and toes where they appear twisted and distorted – this is often called Bouchard’s and Heberden’s nodes. Furthermore, the joint can become swollen, due to the build up of fluid within the joint.
The risk factors for osteoarthritis include; a previous injury to the affected joint, obesity, occupation, physical activities which put added pressure on the joints (including particular occupations), family history, and existing medical conditions (such as diabetes).
