DJD/DDD/OSTEOARTHRITIS/SPONDYLOSIS
Degenerative Joint Disease (DJD), Degenerative Disc Disease (DDD), Osteoarthritis, and Spondylosis are essentially the same thing. They all mean wear and tear in the joints. Time, pressure from gravity, injuries, and general use of the joints eventually lead to wear and tear, just like parts in a car.
