📖What is Knee Arthritis?

Knee arthritis causes pain and stiffness when the cartilage in your knee joint wears down. Learn about symptoms, treatment options, and what you can do to manage your knee pain.

đŸ”ŦWhat Causes It?

  • Normal wear and tear of cartilage over time (most common)
  • Previous knee injury (torn cartilage, ligament injury, or fracture)
  • Repeated stress on the knee from work or sports
  • Abnormal knee alignment (bow-legged or knock-kneed)
  • Inflammatory conditions like rheumatoid arthritis

âš ī¸Risk Factors

â„šī¸

You may be at higher risk if:

  • Being over 50 years old
  • Being overweight (extra weight puts more stress on knee joints)
  • Previous knee injury or surgery
  • Family history of arthritis
  • Jobs requiring repeated kneeling or squatting
  • Playing high-impact sports
  • Female gender (women more likely after menopause)

đŸ›Ąī¸Prevention

  • ✓Maintain a healthy weight - every kg lost reduces knee stress
  • ✓Exercise regularly with low-impact activities (swimming, cycling, walking)
  • ✓Strengthen your thigh muscles (quadriceps and hamstrings)
  • ✓Avoid prolonged kneeling or squatting
  • ✓Wear supportive footwear
  • ✓Treat knee injuries promptly and properly
  • ✓Stay active but avoid high-impact activities if you have early arthritis
