Introduction

Knee Arthritis is the commonest condition affecting elderly people, causing pain, Swelling, deformity, and difficulty in walking. Most of the time, Arthritis is due to the aging process (Osteoarthritis), but even the disease like Rheumatoid Arthritis can cause painful Arthritic Knee.

Know your Knee Joint

  • The Knee joint is consists of three bones.
  • 1. Femur – Lower end of the thigh
  • 2. Tibia – Upper end of the leg
  • 3. Patella (Kneecap).
    Joint surfaces are covered with smooth glistening lining called as a Cartilage. With advancing age or disease process like Rheumatoid Arthritis, the Cartilage is destroyed. This results in rubbing of bones on each other which causes pain while standing, walking and squatting. So the Arthritis (Painful Knee) is due to the loss of bone liner (cartilage), whereas underlying bones are usually normal.
