Osteoarthritis Clinical Trials in Sacramento, CA

The goal of this clinical trial is to understand the patient and clinic visit characteristics that affect health outcomes for individuals with knee osteoarthritis (OA) pain using topical diclofenac gel. The main questions it aims to answer are: * What baseline patient characteristics predict response to topical diclofenac? * Does patient physiology during the study visit predict response to topical diclofenac? * Do study visit characteristics predict response to topical diclofenac? Participants will: * attend 2 study visits to complete study questionnaires and have blood drawn * apply topical diclofenac to their knee for 8 weeks * complete biweekly questions about knee pain and diclofenac use between study visits Read Less

Cooled radiofrequency ablation (cRFA) of the knee geniculate nerves is a promising treatment option for knee osteoarthritis, but has variable efficacy. Fluoroscopy is the typical guidance of choice, but uses bony landmarks to target these nerves which have variable positions around the knee. Alternatively, ultrasound allows for targeting based on visualization of bony landmarks, the nerves, and their accompanying vascular structures, and thus may offer greater accuracy. However, there are few studies which directly compare the clinical efficacy of these two guidance options. This study will compare these two options. Read Less
