Orthopedic surgeon Peter van Roermund advocates for knee distraction as an alternative treatment for younger patients with severe knee osteoarthritis.

Mechanism of Action and Joint Distraction

This method involves temporarily placing an external frame, the KneeReviver®, around the knee to gently separate the joint surfaces by 5mm for six weeks. Through this mechanism, the process stimulates cartilage regeneration, leading to reduced pain and improved mobility.

Joint Preservation and Clinical Trials

Unlike knee prostheses, which may require revision surgeries in younger, more active patients, knee distraction aims to preserve the natural joint longer, potentially delaying or avoiding the need for prosthetic implants.

Studies, including the ongoing GODiVA trial in the Netherlands, are evaluating the effectiveness of this technique. Preliminary results indicate cartilage regeneration and improved bone quality beneath the cartilage.

While the procedure requires wearing an external frame for six weeks and carries a risk of infection at the pin sites, advancements in care have reduced infection rates.

Van Roermund hopes that knee distraction will gain broader recognition and be included in standard health insurance coverage.
