Why Weight Management Is Essential for Knee Pain and Arthritis

The Centers for Disease Control and Prevention (CDC) emphasizes weight management as a key strategy in managing knee pain and arthritis.

Excess body weight increases mechanical stress on the knee joint during everyday activities such as walking, climbing stairs, and standing up. Over time, this increased load can accelerate cartilage breakdown and worsen pain.

What the CDC Highlights

• Excess weight increases joint loading and arthritis progression

• Weight loss reduces pain and improves function

• Even modest weight reduction can lead to meaningful symptom relief

Why It Works (Biomechanics)

1. Reduced compressive force on the knee joint

2. Lower inflammatory load associated with excess adipose tissue

3. Improved movement efficiency and balance

Practical Recommendation

Weight management should be combined with:

• Low-impact aerobic exercise

• Strength training for the lower limbs

• Education and long-term habit change
