Which of the following is a modifiable risk factor for osteoarthritis?
Age over 60 years
Female gender
Family history of osteoarthritis
Obesity
The Correct Answer is D
Obesity is a modifiable risk factor for osteoarthritis. Excess body weight puts increased stress on weight-bearing joints, such as the knees and hips, leading to accelerated wear and tear of the joint cartilage.
a. Age over 60 years is a non-modifiable risk factor for osteoarthritis. While the risk of osteoarthritis increases with age, the age itself cannot be modified.
b. Female gender is a non-modifiable risk factor for osteoarthritis. Women have a higher risk of developing osteoarthritis compared to men, but gender cannot be modified.
c. Family history of osteoarthritis is a non-modifiable risk factor. Having a family history of the condition increases the risk, but it cannot be modified.

b. Unlike rheumatoid arthritis, osteoarthritis is not characterized by joint inflammation and swelling.
d. While osteoarthritis primarily involves synovial joints, it is not limited to these joints.
Correct Answer is B
Explanation
MRI is the most appropriate diagnostic test to confirm the diagnosis of osteoarthritis. It can provide detailed images of the affected joints, allowing the healthcare provider to assess the joint structures, cartilage, and bone for signs of osteoarthritis. Rheumatoid factor (RF) blood test and C-reactive protein (CRP) blood test are used to diagnose inflammatory arthritis conditions like rheumatoid arthritis, not osteoarthritis. Synovial fluid analysis is usually performed to assess for infection or inflammation in the joint, not to diagnose osteoarthritis.
