Knee Osteoarthritis (Gonarthrosis): Prevention

To prevent gonarthrosis (knee osteoarthritis), attention must be paid to reducing individual risk factors.

Behavioral risk factors

  • Consumption of stimulants
    • Alcohol – ≥ 20 glasses of beer/week lead to a significant increase in coxarthrosis (hip osteoarthritis) and gonarthrosis (knee osteoarthritis); individuals who drank 4 to 6 glasses of wine per week had a lower risk of gonarthrosis
    • Tobacco (smoking) – nicotine abuse promotes loss of articular cartilage in the knee joint
  • Physical activity
    • Underloading of the cartilage:
      • Lack of physical activity – since cartilage gets its micronutrients from the synovial fluid, it relies on the joint being moved for cartilage growth
      • Nutritive damage (eg, long rest in a cast).
    • Overloading of the cartilage:
      • Competitive and high-performance sports (e.g., soccer players).
      • Long-lasting heavy physical stress, e.g., in the profession (construction workers, especially floor layers).
  • Overweight (BMI ≥ 25; obesity) – leads to overuse of the joints.

Prevention factors (protective factors)

  • High dietary fiber intake was associated with a lower incidence of symptomatic knee joint osteoarthritis (risk in the quarter with the highest intake (Q4: 21.9 g/d) 30% lower than in the quarter with the lowest intake (Q1: 9.1 g/d)).
