Trial summary

Recent works in interventional radiology have shown interesting results in the treatment of musculoskeletal inflammatory sites by arterial embolization. Supra-selective arterial embolization has been successfully developed by Dr. Okuno (Japan) to manage moderate to severe knee osteoarthritis. Read more about this study

About this study

Official title: ARTERIAL EMBOLIZATION OF PERSISTENT GENICULATE ARTERIES FOR CHRONIC PAIN MANAGEMENT AFTER TOTAL KNEE-REPLACEMENT ARTHROPLASTY: A FEASIBILITY STUDY (KNEE EMBOLISATION)

Recent works in interventional radiology have shown interesting results in the treatment of musculoskeletal inflammatory sites by arterial embolization. Supra-selective arterial embolization has been successfully developed by Dr. Okuno (Japan) to manage moderate to severe knee osteoarthritis. Also, inflammation of the surgical site mediated via geniculate arteries is a major cause for persistent chronic post-operative gonalgia.

Read the detailed description

Hypothesis: Selective arterial embolization of persistent geniculate arteries could reduce chronic post-operative gonalgia after TKA with minimally invasive approach.

Objective: To evaluate the feasibility of selective arterial embolization of persistent geniculate arteries to reduce chronic post-operative gonalgia after TKA.

Material and methods: This study is a single-center, prospective, feasibility study. Patients will be recruited after rheumatology consultation for chronic post-operative gonalgia, more than 6 months after TKA for moderate to severe gonarthrosis. Eligible patients are adults with moderate to severe chronic post-operative gonalgia (Visual Analysis Scale (VAS) > 50mm) and degraded life quality (assessed by SF36 score), despite at least 3 months of optimal medical treatment. Non-inclusion criteria are mainly other rheumatologic or orthopedic severe diseases, severe surgical complications. Under local anesthesia, with homolateral antegrade femoral access, patient will undergo selective arterial embolization of persistent and aberrant peri-prosthetic arteries using HydroPearl® 200µm Mircospheres. Follow-up consultations will be scheduled at D1, M1, M3, M6 and M12. For a significance level of α=0.05 and power of 80% we require a cohort of 24 patients.

Questions about this trial

What is this clinical trial studying?

A study testing arterial embolization in people with Musculoskeletal Inflammatory, run by Assistance Publique Hopitaux De Marseille at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 12 Aug 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact vincent VIDAL (vincent.vidal@ap-hm.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

arterial embolization (time frame: 12 MONTHS). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Aug 2021.
