Arthritis is a degenerative joint condition characterised by pain, stiffness, swelling, and reduced joint movement. It commonly affects weight-bearing joints such as the knees, hips, spine, and shoulders. Arthritis can significantly interfere with daily activities and quality of life if not managed properly. Early diagnosis helps in slowing disease progression and controlling symptoms. Treatment aims to relieve pain, maintain joint function, and improve mobility. Management options include medication, physiotherapy, lifestyle modification, and joint care techniques. In advanced cases, surgical intervention such as joint replacement may be recommended. With proper treatment and regular care, patients can lead a comfortable and active life.
