Eredeti leírás

Genicular Artery Embolization for Reducing Pain in Symptomatic Knee Osteoarthritis: A Pilot Randomized Sham-Controlled Study (SHAM-PAIN) is a NIH-NIAMS funded project designed to assess enrollment feasibility and detect any differences between GAE and a similar sham intervention in reducing KOA-related pain at 3 months as measured by the Knee injury and Osteoarthritis Outcome Score (KOOS) pain subscore. Additionally, this study aims to determine the magnitude of difference in pain response between GAE and sham to adequately power a larger, more definitive randomized sham-controlled trial (RCT). The influence of psychosocial and psychocognitive factors, changes in analgesic use, and conditions of knee joint cartilage and effusion will similarly be explored to determine their impacts on perceived pain response to GAE.A teljes eredeti leírásKevesebb

Bevonási feltételek: Patients aged 40-80; Bilateral or unilateral knee pain attributed to osteoarthritis (treat the knee with greater pain-if equal, patient chooses); Grade 2-4 osteoarthritis on standing weight-bearing knee radiographs per the Kellgren-Lawrence grading scale; Knee pain > 6 months, refractory to conservative non-operative management, and scored ≥ 4 on Visual Analog Scale (VAS) (e.g., rest, activity modification, weight control, bracing, supervised physical therapy, nonsteroidal anti-inflammatory drugs (NSAIDs), acetaminophen, oral opiates, intra-articular hyaluronic acid, PRP, stem cells, and/or oral/injectable corticosteroids); Refusal of intra-articular corticosteroid injection.

Kizáró feltételek: Corticosteroid injection of the affected knee within 3 months of enrollment; Previous surgery of the affected knee (e.g., meniscus repair, meniscectomy, anterior cruciate ligament (ACL)/posterior cruciate ligament (PCL) reconstruction, chondroplasty, microfracture, loose-body removal, synovectomy, lateral release, patellar/quadriceps tendon repair, total or partial knee replacement, osteotomy, cartilage transplant), except diagnostic arthroscopy; Long-acting corticosteroid use within 6 months (3 months for short-acting); Suicide attempt or suicidal behavior within 30 days before screening; Active malignancy; Active infection of the affected knee; Peripheral arterial disease of the treated extremity (Rutherford Grade 2 or greater); Type 1 diabetes mellitus; History of reaction to contrast media, bronchial asthma, or allergic disorders; History of hypersensitivity to gadolinium-based contrast agents (GBCAs); Major depressive disorder within 2 years before screening; Other severe psychiatric disorder (e.g., schizophrenia, bipolar disorder); Any other condition, unwillingness, or inability that, in the investigator's opinion, could jeopardize the subject's safety or protocol compliance; GFR < 60 mL/min/1.73 m²; Rheumatoid arthritis or other seronegative arthropathy; Grade 0-1 osteoarthritis per Kellgren-Lawrence grading scale of the affected knee; Pregnancy or expected pregnancy; Anaphylactic reaction to iodinated contrast; Moderate to severe pain in other ipsilateral lower-limb joints (ankle, hip) with VAS > 4; Body weight > 400 lbs (unsafe for angiography); History or other evidence of acute kidney injury (AKI); Chronic widespread generalized pain >4 on VAS pain scale, including neuropathic pain; Diagnosis of fibromyalgia; Considering total knee replacement in the next year.
