Brief Summary:
Purpose: To evaluate embolization as a treatment for OA related knee pain versus placebo to demonstrate the actual effect of embolization on pain and disability.
Participants: There will be 21 subjects enrolled over the age 40 with knee pain secondary to arthritis.
Procedures (methods): This will be a single-blinded randomized-controlled study of GAE versus placebo in a small population with knee pain secondary to arthritis to determine safety and efficacy. Clinical procedures and evaluations will consist of a preoperative screening assessment to determine if the potential study subject meets the inclusion and exclusion criteria, enrollment, surgical procedure for geniculate artery embolization, and follow-up visits at 24 hours, 2 weeks, 1, 3, 6, \& 12 months. An MRI may be performed after the 1-month visit.
Detailed Description:
This will be a single-blinded randomized-controlled study of GAE versus placebo in a small population with knee pain secondary to arthritis to determine safety and efficacy. After Institutional Review Board (IRB) approval of a written informed consent and over, approximately a 24 month duration, N=21 subjects will be recruited. Only subjects ≥ 40 years will be screened for study recruitment. Subjects will be randomized in a 2:1 ratio of GAE:Placebo and will be blinded from study treatment (see flow chart below). The placebo procedure will be a diagnostic angiogram of the knee, without embolization. Appropriate measures will be taken to ensure patients and nursing staff caring for the patient are blinded to assignment. Each patient will be told at the time of recruitment that they may be randomly assigned to sham, but if after 1 month they have not had symptom improvement, their assigned procedure would be revealed and, if they had undergone a sham procedure, they will be allowed to proceed with embolization. This second procedure should be shorter than a complete angiogram and embolization, as the detailed angiogram will not need to be repeated, and therefore both arms will have similar total radiation dose.
Clinical procedures and evaluations will consist of a preoperative screening assessment to determine if the potential study subject meets the inclusion and exclusion criteria, enrollment, surgical procedure for geniculate artery embolization, and follow-up visits at 24 hours, 2 weeks, 1, 3, 6, \& 12 months. An MRI may be performed after the 1-month visit.
