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.

Knee joint distraction is a joint preserving

surgical treatment with use of the KneeReviver

Extensive study about knee distraction !

We kindly present you the result of an extensive study about knee distraction as treatment for painful osteoarthritis of the knee at relatively young patients.

The study was done in the department of rheumatology and immunology at the UMC Utrecht by PhD student Mylène Jansen. It resulted in a beautiful thesis which she will defend at June 15 2021. The research was a joint effort with several orthopedics in the Netherlands and Belgium during the last 3.5 years.

The extensive research gives an insight in the clinical outcome of knee distraction treatment also in comparison with other treatments like high tibial osteotomy and total knee replacement.

During this research, patients treated with ArthroSave’s KneeReviver were also taken into account. PhD student Mylène Jansen did also research at the possible repair of degenerated cartilage and sclerotic subchondral bone during knee distraction.
