Efficacy of Genicular Nerve Alcohol Neurolysis in Knee Osteoarthritis Pain

Status Completed

Clinical Trial Summary

This study aimed to evaluate the efficacy of genicular nerve alcohol neurolysis in the treatment of pain caused by chronic knee osteoarthritis. The investigators will evaluate the efficacy of genicular nerve alcohol neurolysis using the numeric rating scale (NRS) and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). NRS and WOMAC scores will be evaluated before, 1, and 3 months after the procedure.

Clinical Trial Description

Alcohol neurolysis of the genicular nerve is a procedure that involves injecting alcohol around the nerve branches that supply sensation to the knee joint. The alcohol destroys the nerve fibers and blocks the transmission of pain signals from the knee to the brain. This technique can be used to treat chronic knee pain caused by osteoarthritis (OA). Several studies have reported that alcohol neurolysis of the genicular nerve can provide significant pain relief and functional improvement in patients with knee OA or postoperative pain. For example, Dass et al. (1) reported two cases of alcohol neurolysis of the genicular nerve using fluoroscopy and ultrasonography in patients with knee OA or persistent postsurgical pain of the knee. Both patients had more than 50% reduction in their numerical rating scale (NRS) scores and improved range of motion and quality of life at 3 months follow-up. Ultrasonography-guided genicular nerve alcohol neurolysis is prominent with its easy applicability and low cost. There are no studies in the literature evaluating the efficacy of genicular nerve alcohol neurolysis for chronic knee OA. In this prospective study, the investigators will evaluate the NRS and WOMAC scores of patients who underwent genicular nerve alcohol neurolysis for chronic knee OA before, 1, and 3 months after the procedure. In addition, the incidence of procedure-related adverse events (such as paresthesia) recorded in patient records will be analyzed. 1. Dass RM et al.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
