Joints are involved in almost every activity that you do. Walking, running, bending, and turning all require the joints of the hip and knee. Normal healthy joints allow for these movements to occur easily and without pain. However, when joints become diseased or injured, the pain that results can become so severe that normal movement becomes impossible. If you are suffering from joint pain it is important that you understand the causes of joint pain as well as treatment options.
One of the most common causes of joint pain is arthritis:
- Osteoarthritis - a wearing out or breaking down of cartilage in the joints, also known as "wear-and-tear" or degenerative arthritis. As the cartilage wears away, the bone ends rub against each other causing pain and stiffness.
- Post-traumatic Arthritis - cartilage is damaged due to an injury and does not heal properly.
- Avascular Necrosis - occurs when the bone is deprived of normal blood supply. Without normal blood supply, the bone is deprived of proper nutrition and can become weakened and collapse and damage the joint cartilage.
- Rheumatoid Arthritis - a disease that produces chemical changes in the soft tissue that lines surfaces within joint , which causes it to thicken and become inflamed.
Whether your joint pain is caused by arthritis or injury, in many cases joint pain can become worse by avoiding movement, causing the bones and muscles to become weakened and more difficult to move.
