Knee osteoarthritis

What is knee osteoarthritis?

Knee osteoarthritis, or gonarthrosis, leads to degeneration of the cartilage of the joint (menisci). Over time, the cartilage disappears completely and the bones rub directly against each other.


Where does it come from?

Two sources of knee osteoarthritis can be distinguished:

  • Primitive (or idiopathic):

This comes from an alteration of the chemical composition of the joint, triggering progressive deterioration of the cartilage.

  • Secondary (or mechanical):

This is mainly caused by external factors, such as trauma (fracture, contusion, tear), joint stress (work, sports), instability of the knee, or excess weight and sedentary lifestyle.


How can it be recognized?

Pain can be of mechanical origin, caused by friction of the joint surfaces, or of inflammatory origin (arthritis). Its main symptoms are:

  • A reduction of the interosseous space in the joint;
  • A progressive deformation in:
    • Genu varum(bow-leggedness)
    • Genu valgum(knock-knee)
  • Pain when walking and going up and down stairs;
  • Swelling and stiffness of the joint.

The evolution of osteoarthritis is generally slow, punctuated by a period of recovery and stoppage of the pain.


Treatment solutions for knee osteoarthritis

  1. Opt for a foot orthosis

Wearing a foot orthosis helps mitigate certain symptoms by offering better stability and restoring the good alignment of the knee.

2.      Wear a knee orthosis

For optimum rehabilitation, the doctor may prescribe a knee orthosis to be worn at all times, or only when engaged in sports or walking. It protects the joint and protects the stability of the knee and the kneecap.
