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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers
