(HealthDay News) -- Knee joints can wear as you age, or after years of high-impact exercise.

Here are ways to help minimize damage to knees, courtesy of the American Academy of Orthopaedic Surgeons:

  • Avoid activities that tend to damage the knees, such as running, tennis, baseball and basketball.
  • Engage in low-impact activities, such as swimming, biking, golf or walking.
  • Talk to your doctor about anti-inflammatory medications, or joint supplements to help preserve the knees. Anti-inflammatory medications may also be injected by your doctor.
  • Physical therapy and icing the knees can help improve function.
  • Protective gear such as a brace, splint or elastic bandage can help support a weakened knee.
