Initiate high-intensity weight-bearing exercises.
Increase dietary intake of calcium and vitamin D supplements.
Avoid all physical activity to prevent further joint damage.

The Correct Answer is D
A. High-intensity weight-bearing exercises can exacerbate pain in patients with osteoarthritis and is not appropriate for alleviating knee stiffness.
B. Calcium and vitamin D supplementation is important for bone health, but it will not directly address the pain and stiffness associated with osteoarthritis.
C. Avoiding physical activity is not recommended for osteoarthritis; instead, moderate exercise can help improve joint function.
