Cooled Radiofrequency vs. Hyaluronic Acid to Manage Knee Pain
This is a prospective, randomized, multicenter comparison study examining the outcomes of subjects with osteoarthritis and knee pain undergoing a procedure to create a radiofrequency lesion of the genicular nerves with the Cooled Radiofrequency Ablation (CRFA) system compared to subjects receiving Hyaluronic Acid (HA). Approximately 168 subjects will be enrolled into this study, with subjects undergoing either CRFA or HA injection in a 1:1 randomization scheme. Follow-up will be conducted for 12 months post-CRFA, with the primary endpoint being completed at month 6. Subjects randomized to the comparison (HA) group will have the option to cross-over to the neurotomy group ...
Corticosteroid/Ropivacaine Versus Corticosteroid/Saline Injections for Knee Osteoarthritis
Corticosteroid injections are commonly used for the symptomatic treatment of knee osteoarthritis. Common practice is to inject the joint with a combination of corticosteroid and local anesthetic, with the rationale of providing longer duration pain relief with the corticosteroid and immediate, though short duration relief with the anesthetic. However, multiple in vitro and animal studies have shown that local anesthetic may be harmful to chondrocytes. Despite this data, use of intra-articular anesthetic remains widespread. Many clinicians believe incorporating the anesthetic is important because it can provide immediate pain relief and facilitate patient confidence in the treatment program. However, there is ...
