Which of the following is an OA risk factor?

• A. Cutting sports
• B. Regular jogging
• C. High-fat diet
• D. Short stature

Answer: (A)

High-load, knee-stress from quick direction changes and pivots increases wear on the joint over time. Cutting sports demand rapid cuts, sudden stops, and twisting motions that put substantial stress on the knee cartilage and ligaments. Repeatedly loading the joint in this way—and the injuries that can come with it, like ligament or meniscal damage—accelerates cartilage breakdown and raises the risk of osteoarthritis later on. Regular jogging isn’t inherently OA-causing at reasonable levels, and can even be protective for weight management and joint function. A high-fat diet isn’t a direct OA risk by itself, though it can contribute to obesity, which is a risk factor. Short stature isn’t an established independent OA risk factor. So the activity with the clearest link to OA risk is the high-stress, cutting-type sports.
