How can one reduce the risk of knee #osteoarthritis?
1. Knee osteoarthritis (OA) causes knee pain. It limits mobility, hampers physical activity and contributes to sedentary lifestyle, which in turn, increases the risk of obesity, diabetes, hypertension, heart attack and stroke.

2. Who are at risk of developing knee OA?
*Non-modifiable risk factors:
Female gender and older age
*#obesity: Increases the risk of knee OA three-times. It also accelerates the progression of disease.

3. Knee injury: Traumatic joint injury is a major risk factor for osteoarthritis, particularly at the #knee (i.e. meniscal damage, anterior cruciate ligament rupture, or direct articular cartilage injury). Ref: doi.org/10.1097%2FBOR.…
4. High #uric acid: The mean serum uric acid level among patients with knee OA is higher than that among patients without knee OA (6.3 mg/dl vs. 5.7 mg/dl). Hyperuricemia is more common among older outpatients with knee OA than among those without knee OA (39% vs. 19%).
5. Poor muscle strength: Weaker knee flexor and extensor muscles increase the risk of knee OA.
6. What measures can prevent knee OA?
Eating diet rich in #whole #grains can be a nutritional strategy to prevent OA. In a 8-year follow up study, people consuming higher amounts of dark bread and cereal #fibers had 32% and 39% lower risk of developing OA knees respectively.

7. Drinking #coffee is associated with a lower risk of radiographic knee OA in women.

8. #weightloss:
Losing weight decreases the risk and progression of knee OA.
Decreasing BMI by 2 units or more over 10 years (~5 kg) is associated with 50% lower risk of developing symptomatic knee OA among women.

9. Recreational #running:
The incidence of knee and hip OA is 3.5% in recreational runners as compared to 10.2% in non-runners.
In competitive or elite runners (>92 km running mileage per week), the incidence of OA is higher (13.3%). Ref: jospt.org/doi/10.2519/jo…

*Obesity, poor muscle strength of hamstrings & quadriceps, sedentary lifestyle, knee injury and occupations involving lifting or carrying heavy weights increase the risk of knee OA.
