About this study
The goal of this clinical trial is to learn if genicular artery embolization (GAE) can improve knee pain and decrease inflammation in adults with knee osteoarthritis. The main question it aims to answer is: \- Does the GAE procedure improve knee pain and decrease inflammation? Researchers will compare synovial fluid samples taken from the knee before and after the procedure. Participants will: * Have a contrast enhanced MRI before and after the procedure * Complete performance-based measures before and after the procedure * Complete questionnaires before and after the procedure
Sponsor: University of Colorado, Denver
You may qualify if…
- ✓ Age ≥ 18 years
- ✓ Planned to undergo genicular artery embolization to treat knee osteoarthritis.
- ✓ Osteoarthritis on knee radiograph (Kellgren-Lawrence score 1-3) within the last 6 months
- ✓ Persistent moderate to severe knee pain (visual analog scale \[VAS\] \>3) for at least 6 months
- ✓ Pain refractory or intolerant to conservative therapies (e.g. analgesia, exercise, weight-loss, joint injections, physical therapy)
- ✓ BMI \< 35 kg / m2
- ✓ Stated willingness to comply with study procedures and availability for the duration of the study
You may not qualify if…
- ✕ Coagulation disturbances not normalized by medical treatment (INR \>1.8 and platelets \<50 x 10\^9/L)
- ✕ Receiving medications for anticoagulation which cannot safely be held for the procedure (e.g ASA for 5 days, Lovenox for 24 hours, Eliquis for 4-6 days depending on creatinine clearance
- ✕ Allergy to iodinated contrast agents not responsive to steroid premedication regimen
- ✕ Active knee joint infection
- ✕ Acute knee injury with surgical indication (MRI evidence of acute fracture or ligamentous injury of the knee)
- ✕ Prior total or partial knee replacement in the subject knee
- ✕ Intra-articular steroid injection within 2 months
- ✕ Untreated lower extremity vascular arterial disease
