Genicular Artery Embolization for Severe Knee Osteoarthritis Pain

Official title: Prospective Randomized Trial Evaluating the Role of Genicular Artery Embolization in Treatment of Persistent Pain in Patients With Severe Knee Osteoarthritis

Run by King Abdullah International Medical Research Center · NCT07763158 · Data updated 2026-11-12

This trial tests whether blocking blood flow to knee arteries can reduce persistent pain in adults with severe knee osteoarthritis who have not improved with standard care.

Is this trial a fit for you?

Likely a good fit

Adults 18 or older with severe knee osteoarthritis (Kellgren-Lawrence grade 3 or higher) who have persistent pain after conservative therapy and are unable to have surgery due to medical conditions.

Probably not a fit

Patients with recent intra-articular injections (within 6 months), prior knee arthroplasty, or conditions like malignancy or renal impairment may not benefit as expected.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

In this randomized trial, adults with Kellgren-Lawrence grade 3 or higher knee osteoarthritis and persistent pain despite conservative therapy are assigned to either genicular artery embolization or continued non-surgical care. Pain and function are measured before treatment and at 6 weeks, 3 months, and 6 months using VAS and the WOMAC index. The study uses opaque envelope randomization and analyzes outcomes with SPSS, comparing embolization to conservative management. Primary focus is pain reduction; secondary focus is improvement in function. Enrollment is conducted at King Abdullah International Medical Research Center in Jeddah, Saudi Arabia.

Why it matters

Potential benefit: If successful, patients may experience meaningful reductions in knee pain and improvements in function without surgery.

How similar studies have gone: Previous studies in similar vascular approaches have shown promise, but this specific embolization strategy for osteoarthritis is relatively novel and its effectiveness remains being established.

Inclusion Criteria:

Adults aged 18 years or older of either sex. Diagnosis of knee osteoarthritis with a Kellgren-Lawrence grade of 3 or higher. Persistent knee pain resistant to conservative treatment for at least 3 months. Conservative treatment includes NSAIDs, physiotherapy, weight reduction programs, and intra-articular injections.

Patients with multiple comorbidities who are indicated for operative treatment, such as total knee arthroplasty, for pain management but are unable to undergo surgery due to their medical status.

Exclusion Criteria:

Previous knee arthroplasty in the affected knee. Known malignancy. Local infection. Rheumatoid arthritis. Intra-articular injection in the affected knee within the previous 6 months. Body weight greater than 150 kg. Renal impairment. Irreversible coagulopathy. Peripheral vascular disease.
