Osteoarthritis is a degenerative disease that causes the loss of cartilage – which acts as a cushion type for joint – between the bones of the victim.

Although it usually affects males below the age of 50 years, it is more common in women when they approach 60 years of age.The most common cause of osteoarthritis is normal wear on joints, such as the age of the patient. With the passage of time, the cartilage in the joints of the victim degenerates cartilage gradually filled with water and protein begins to scales or form cracks.
