Osteoarthritis is a degenerative joint disease that primarily affects the cartilage, the protective tissue that cushions the ends of bones. Over time, the cartilage wears down, leading to pain, stiffness, and reduced mobility. It is one of the most common forms of arthritis and often affects weight-bearing joints like the knees, hips, and spine. Factors like aging, obesity, joint injuries, and genetic predisposition can accelerate its progression. Dr. Anu Daber, a renowned Osteoarthritis Treatment Specialist in Gurgaon Sector 52, emphasizes the importance of early diagnosis to prevent further joint damage and improve joint function.
