Knee osteoarthritis is a degenerative joint disease that causes pain and stiffness in the knee joint. It is one of the most common knee conditions for the elderly, often explained as a “wear and tear” problem, and can severely impact their quality of life. Knee osteoarthritis occurs when there is a loss of articular cartilage within the knee, causing the joint space within the knee to narrow and eventually lead to bone-on-bone grinding during movement. As the condition progresses, bony spurs will develop and patients are often able to feel these painful bony lumps around the knee joint.
It’s important to note that not everyone who experiences osteoarthritis in their knees has experienced a traumatic injury or overuse of the joint. Some people simply have a genetic predisposition to developing knee osteoarthritis as they age.
