Degenerative Joint Disease or Osteoarthritis is a chronic progressive degenerating disorder that affects your joints and results in chronic pain, immobility, and joint stiffness. Out of the many forms of arthritis, it is the most common. Your joints are complex structures made from the coalition of several different components. One such component is the articular cartilage that lines the part of the bone, forming the joint.
In osteoarthritis, the cartilage degenerates progressively, and as a result, the bony surfaces rub against each other. This further weakens the integrity of the joint and ultimately results in symptoms. Your hip and knee joint are most susceptible to arthritis.
