Knee osteoarthritis is a common condition that causes pain, stiffness, and swelling in the knee joint. One of the best ways to manage knee osteoarthritis is through gentle and regular exercise. Exercise can strengthen the muscles around the knee, reduce pain, and improve mobility. This article will help you understand the best exercises for knee osteoarthritis, how to do them safely, and how they can improve your daily life.

What is Knee Osteoarthritis?

Knee osteoarthritis is a condition where the cartilage in the knee joint wears down over time. Cartilage acts like a cushion between the bones. When it breaks down, the bones rub together, causing pain and stiffness. This condition can make walking, bending, or climbing stairs very difficult.


Why Exercise is Important for Knee Osteoarthritis

Exercise may sound difficult when you have joint pain, but the right type of movement can:

  • Reduce pain and swelling
  • Improve joint flexibility
  • Strengthen muscles around the knee
  • Support balance and stability
  • Help maintain a healthy weight

Regular exercise can slow the progression of osteoarthritis and improve your quality of life.
