About the Study
Currently Recruiting: Participants
Study Timeline: This study is expected to conclude in August 2024.
Study Drug/Intervention: Using a stepped‑care model, Phase 1 participants will be randomly assigned to one of 3 minimally‑invasive treatments, 1A) best practices, 1B) duloxetine in addition to best practices, and 1C) duloxetine combined with PainTRAINER, a structured cognitive-behavioral therapy (CBT)‑informed web-based program, in addition to best practices. Phase 1 participants that note interest in receiving additional treatment, and those inappropriate for Phase 1 care, will be randomly assigned to more invasive Phase 2 procedures, including 2A) intra-articular hyaluronic acid, steroid, and local anesthetic injection (HA+), 2B) genicular nerve block (GNB) with a long-acting local anesthetic, and 2C) radiofrequency ablation (RFA).
