What is Elbow Osteoarthritis?
Osteoarthritis is a type of arthritis that is related to age, commonly called the “wear and tear” form of arthritis. It is more common in patients over the age of fifty and develops due to the cartilage that cushions the bone, becoming softer and wearing away, allowing the bones to rub against one another. Over time, the elbow joint becomes stiff, and movement becomes painful.
The bones that meet to form the elbow joint are covered with cartilage, protecting them while allowing easy movement. Also, within the elbow joint is a smooth tissue called synovial membrane, which covers all the surfaces that don’t have cartilage. In a healthy elbow, that membrane makes a fluid that lubricates the cartilage and reduces any friction created during movement. When osteoarthritis develops in the elbow, the cartilage becomes rougher and wears away, which makes the joint space more narrow and increases the friction, resulting in elbow pain.
