Osteoarthritis of the knee is a common condition that occurs when the protective cartilage within the knee joint gradually wears down. As the cartilage becomes thinner, the bones may have less cushioning during movement, which can lead to pain, stiffness, swelling, and reduced range of motion. Symptoms may develop gradually and can become more noticeable with activities such as walking, climbing stairs, standing, or getting up from a chair.
Knee osteoarthritis can affect everyday mobility and quality of life, but symptoms and progression can vary from person to person. Maintaining healthy joint movement, strength, flexibility, and overall physical activity can be important for supporting knee function. Understanding the condition and recognizing changes in symptoms can help people work with their healthcare provider to develop an appropriate plan for maintaining mobility and managing discomfort.
