Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this study is to investigate the safety and efficacy of geniculate artery embolization (GAE) as pain treatment in patients with mild to moderate knee osteoarthritis.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a single arm, prospective, pilot study investigating the safety and efficacy of GAE as pain treatment in patients with mild to moderate knee osteoarthritis. Patient related outcome measurements (PROMs), physical tests and several image modalities will be conducted.

It may form the grounding for further research in the shape of a larger randomized clinical trial.

The hypothesis is, that GAE will reduce synovitis and thereby pain in the patient group. This may secondary improve physical function and reduce consumption of analgesics.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Mild to moderate knee osteoarthritis (Kellgren Lawrence Score 1-3)

Geniculate artery embolization will be performed in all eligible participants.

Group Type EXPERIMENTAL

Transarterial geniculate artery embolization

Intervention Type PROCEDURE

The procedure will be performed in local anaesthesia. An antegrade percutaneous transfemoral approach with super-selective catheterisation of geniculate neovesselswill be performed and subsequently the target will be pruned with microspherical embolic material.
