Select the one that is not related to osteoarthritis.

Options

A. In osteoarthritis, large weight - bearing joints are affected.
B. The articular cartilages get eroded.
C. It is a degenerative joint disease occurring in the late middle age.
D. It is caused due to excessive formation of uric acid.

Answer

To solve the question of which option is not related to osteoarthritis, we can follow these steps:

### Step 1: Understand Osteoarthritis
Osteoarthritis is a degenerative joint disease characterized by the breakdown of cartilage in joints, leading to pain and stiffness. It primarily affects weight-bearing joints such as the knees and hips and is often associated with aging and obesity.

### Step 2: Analyze the Options
We need to evaluate each option provided in the question to determine which one does not relate to osteoarthritis.

1. **Large weight-bearing joints are affected**: This statement is true. Osteoarthritis commonly affects large joints like the knees and hips.

2. **The articular cartilage gets eroded**: This is also true. In osteoarthritis, the cartilage that cushions the joints wears away, leading to pain and reduced mobility.

3. **It is a degenerative joint disease occurring in late middle age**: This statement is correct as osteoarthritis is often diagnosed in individuals over the age of 45.

4. **It is caused due to excessive formation of uric acid**: This statement is incorrect in the context of osteoarthritis. Excessive uric acid is associated with gout, not osteoarthritis.

### Step 3: Identify the Incorrect Option
From the analysis, the fourth option regarding excessive formation of uric acid is not related to osteoarthritis. Therefore, this is the correct answer to the question.

### Final Answer
The option that is not related to osteoarthritis is the one that states it is caused due to excessive formation of uric acid.
