Osteoarthritis is a joint disease caused by trauma, obesity, or most often a consequence of normal aging.
The most affected area in osteoarthritis is joint cartilage.
Cartilage consists of smooth tissue that covers the ends of bones in joints such as the knee, hip, and wrist. When cartilage is properly functioning, your bones effortlessly glide over each other with each movement. Cartilage also helps your joints absorb the impact of movement.
