Comparison of the Effects of Normal Saline, Hypertonic Saline, and Hyaluronidase on Patients with Postoperative Relapse of Carpal Tunnel Syndrome: A Randomized Controlled Trial

Background

Recurrent carpal tunnel syndrome affects up to 25% of patients following surgical decompression, causing significant therapeutic challenges. Hydrodissection, a minimally invasive technique that alleviates perineural adhesions, has shown promise for symptom relief. However, optimal injectable agents for hydrodissection in postoperative relapse of carpal tunnel syndrome remain under investigation.
