(HealthDay News) -- Arthritis can affect any joint, but weight-bearing joints such as the knee are particularly vulnerable.

The American Academy of Orthopaedic Surgeons mentions these common symptoms of knee arthritis:

  • Swelling and stiffness.
  • Trouble straightening or bending the knee.
  • Pain that tends to worsen in the morning, after resting, or after activities such as climbing stairs, kneeling or walking.
  • Pain and stiffness that seem to coincide with changes in weather.
