Obese individuals are directly loading weight bearing joints (hip, Knee & ankle) resulting in damage to cartilage lining.
There is also indirect relation between obesity and arthritis as explained below.
Of all the joints in the body knee joint is the major weight bearing joint.The ends of bones in the knee joint are covered by special lining called cartilage. Cartilage lining aids in smooth motion of joint and acts as shock absorber. When this cartilage lining is subjected to repetitive high stresses it loses its nutrition and elasticity, which in turn results in early wear and tear. Many studies have shown relationship between body mass index (BMI) and development of osteoarthritis and knee pain.Statistics from around the world are showing average rise in BMI and is the incidence of arthritis.
Some experiments have found that hormone called Leptin is released from extra body fat, which plays a role in development of osteoarthritis of knee. Extra body fat content in the body releases toxins that can promote inflammation which can also damage cartilage.
