Knee Osteoarthritis

Published: July 21, 2020

What is knee osteoarthritis?

Knee osteoarthritis is a condition affecting the cartilage in the knee joint. Cartilage covers the ends of the bones providing a smooth surface for the joint to glide across when we bend and straighten our knees. Osteoarthritis can cause the cartilage to wear thin and develop cracks, exposing the underlying bone. This reduces the smoothness of the joint leading to pain and stiffness in the knee. It is common for symptoms of knee osteoarthritis to fluctuate in duration and intensity.


Common symptoms of knee osteoarthritis include:
  • Stiffness in the morning or after prolonged sitting
  • Pain with prolonged periods of walking or standing
  • Difficulty with activities such as going up and down stairs
  • Knee joint swelling
  • Clicking, clunking, crunching or catching within the joint
  • Reduced joint flexibility
  • A feeling of unsteadiness
  • Feeling of weakness in the surrounding muscles, particularly the front of the thigh


Severe knee osteoarthritis currently affects more than 56,000 Australians. This number is expected to rise to 69,000 by 2029.  All too often knee joint replacement surgery is seen as the only option for treatment of this debilitating condition. However, research recently completed by Monash and Latrobe Universities found that a structured physiotherapy-led program can help up to 68% of people avoid surgery. This study is adding to the growing evidence that structured and consistent physiotherapy leads to the best outcomes for knee osteoarthritis.
