question 52

a. age
b. obesity
c. sports participation
d. history of joint injury
e. all the above
f. a, b, & d only.

Explanation:

• Age: As people age, the cartilage in joints wears down over time, increasing the risk of osteoarthritis.
• Obesity: Excess weight puts more stress on joints (especially weight - bearing joints like knees and hips), accelerating cartilage damage.
• History of joint injury: Previous joint injuries (such as fractures, ligament tears) can disrupt the normal structure and biomechanics of the joint, leading to early - onset or more severe osteoarthritis.
• Sports participation: Intense or repetitive sports activities can cause micro - trauma to joints over time. For example, sports like football (with frequent impacts on knees) or long - distance running (repeated stress on lower limb joints) can increase the risk.

Answer:

E. All the above
