Brief Summary

Geniculate Artery Embolization (GAE) has recently been described and studied as a palliative treatment for osteoarthrosis-related knee pain in patients un-eligible for surgical intervention. This treatment is based on the hypothesis that hypervascularization and associated increased nerve proliferation are possible sources of chronic pain following the morphological changes of osteoarthrosis. A large animal model has shown digital subtraction arteriography to be well correlated to both the histological findings of synovial inflammation and synovial contrast enhancement on magnetic resonance imaging. This embolization technique has also been applied to other regions of the musculoskeletal system including the elbow and the shoulder.

Outcome Measures

Primary Outcomes (1)

  • Pain control VAS

    The pain intensity is assessed using VAS (horizontal line 100 mm in length). Subjects mark the VAS with a single vertical line to indicate their current pain level, with 0 mm representing "No Pain" and 100 mm representing "Worst Possible Pain". * Expected mean VAS pre treatment: 7 * Expected mean VAS at 1, 3, 6 and 12 months: 3-4 (50% reduction)

    12 months

Secondary Outcomes (2)

  • Function

    12 months

  • Radiological examinations

Study Arms (1)

Geniculate Artery Embolization Arm

EXPERIMENTAL

Single-arm prospective study of geniculate artery embolization for symptomatic knee osteoarthritis

Procedure: Geniculate Artery Embolization

Interventions

1. Conscious sedation : midazolam and fentanyl 2. Local anesthesia : Lidocaine 2% subcutaneous 3. Retrograde or anterograde common femoral artery access - 4Fr introducer 4. Sub-therapeutic anticoagulation (heparin 2000 IU IA) 5. Lower extremity arteriography 6. Selective and supra-selective catheterization of geniculate arteries supplying painful region of the knee 7. If abnormal arterial blushes are demonstrated selective and supra-selective embolization will be performed with Embozene microspheres (100 microns to 200 microns) - cold saline or ice-packs sac to be applied to overlying skin if significant cutaneous arteries are demonstrated at angiography. 8. Angiographic end-points: embolization of abnormal blush while preserving the parent vessel 9. Arteriotomy closure (manual compression or closure device)
