Innovations in Genicular Outcomes Registry (iGOR)

The registry will capture prospective data on patients receiving pain management for chronic pain due to knee osteoarthritis (OA) or pain optimization for knee arthroplasty due to knee OA. The OA pain therapies may include cryo nerve block, radiofrequency ablation (RFA), intra-articular (IA) corticosteroids, viscosupplementation, opioids, and others (e.g., non-steroidal anti-inflammatory drugs [NSAIDs]).
