Are you a patient with painful knee osteoarthritis below the age of 65 years? Return to your active life after a six weeks treatment with the KneeReviver.


The KneeReviver unloads the damaged knee joint by putting the knee joint surfaces on a short distance. With this temporary unloading treatment the knee joint tissues regenerate.

For whom

Patients diagnosed with knee osteoarthritis, not responding to conservative therapy, probably already indicated for a knee replacement, under the age of 65 years old.


This unloading treatment is studied in medical research groups for > 10 years, resulting in knee joint preservation, decrease of pain, increase of function, and postponing a knee replacement.

Postponing the need for total knee replacement,

avoiding complex revision surgery

The KneeReviver

  • Consists of 2 tubes placed on both sides of the knee
  • Is fixated to the bone by eight bone pins
  • Unloads the knee joint by creating space between the joint surfaces
  • It is allowed to bear weight during treatment, however it is not possible to bend the knee

The Knee Reviver is developed by ArthroSave, in collaboration with orthopaedic surgeons, researchers and patients. It is the only device with intended use for knee joint distraction.

New research results published in relation to Knee Joint Distraction

A cooperation between UMC Utrecht, ImageBiopsy Lab, University of Oxford and Imperial College London resulted in new research results using artificial intelligence.

The objective of the study was to analyze anatomical changes after KJD in patients treated in regular care using an automatic artificial intelligence-based measurement method, and to relate these changes with patient-reported knee pain and synovial fluid biomarker levels.

The conclusion is that the automatic artificial intelligence-based radiographic measurements show improved joint structure in most patients after KJD in regular care. The joint space width increased significantly and was associated with synovial fluid biomarker level changes and even with improvements in pain as experienced by these patients.

ArthroSave raises new investment round to battle severe knee osteoarthritis

Patients with knee osteoarthritis have a damaged knee joint and suffer from persistent pain every day. In Europe alone over 2.2 million patients are affected by knee osteoarthritis and prevalence is rising dramatically, due to rising obesity rates and aging population.

Karianne Lindenhovius, CEO and co-founder of ArthroSave, explains: “ArthroSave has developed the KneeReviver enabling knee joint distraction as a joint preserving solution. Knee joint distraction with the KneeReviver is a temporary treatment that unloads the knee joint for six weeks. This results in relief of pain and improvement of function. Due to regeneration of the joint, the original knee joint will be preserved. This will postpone the knee replacement surgery for 10 more years and will prevent complex revision surgery later in life.”
