Orthopedic, Arthroscopy & Joint Replacement Surgeon in Kalyan, Dr Amit Garud, explains that osteoarthritis is the most common form of arthritis, caused by gradual wear and tear of joint cartilage. It commonly affects the knees, hips, and spine—joints that bear most of the body’s weight. Major risk factors include: · Agerelated cartilage degeneration · Obesity, which increases pressure on joints · Previous joint injuries · Family history of osteoarthritis · Repetitive stress from work or sports · Poor joint alignment or biomechanical issues Early intervention helps slow progression, reduce pain, and maintain mobility. If you experience persistent joint discomfort, consult your doctor early.
