Osteoarthritis of the knee 

In a healthy state, joint cartilage facilitates the movement of the joints and provides a cushioning effect. Osteoarthritis is a sign of wear and tear of these joint surfaces. Gonarthrosis, i.e. osteoarthritis of the knee joint, is one of the most common disorders of the knee. Consequences of this wear and tear and destruction of the joint cartilage are pain, stiffness and instability of the knee. Age-related wear and tear is not the only cause of cartilage damage. It can also result from the interaction of several causes. 

The wear and tear of the joint cartilage is degenerative. That means it cannot be healed. Therefore, the focus of treatment is to reduce the pain caused by the osteoarthritis of the knee and to keep the knee mobile to limit the progression of the osteoarthritis. In cases of advanced osteoarthritis, an artificial joint replacement may be required as a last resort. The earlier an onset of osteoarthritis is detected, the more effectively action can be taken. The aim, however, is to take preventative measures to avoid damage to the cartilage. 

Persistent knee pain should always be checked by a doctor, who will make an exact diagnosis and start treatment.

Causes can include


  • continuing inappropriate or excessive strain
  • knock knees or bandy legs
  • injuries to the knee such as a fracture that affects the joint
  • excess weight
  • rheumatoid arthritis (chronic inflammatory disease) in the joint



  • pain behind the kneecap after a long rest sitting down
  • cracking sounds in the knee during movement
  • increased pain when carrying heavy loads
  • excess weight
  • start-up pain: pain after extended periods of sitting or in the morning
  • pain when climbing stairs

In the event of osteoarthritis of the knee, exercise that is gentle on the joint, such as water aerobics or swimming, is particularly recommended and beneficial.

Relief for osteoarthritis of the knee with JuzoFlex Genu Xtra

JuzoFlex Genu Xtra Ghost Aufnahme

JuzoFlex Genu Xtra supports and relieves the knee joint. The compression effect of the knee support also alleviates pain during movement. This is important because gentle mobilisation is a particularly essential factor during the healing process. Movement stimulates circulation in the knee joint and therefore the supply of nutrients to joint cartilage, which is compromised in the case of osteoarthritis of the knee. This positive effect is additionally increased with a gentle massage effect by the friction nubs of the patella ring. The patella ring also ensures that the fluid which causes swelling is massaged, draining it from the tissue that surrounds the kneecap.
