Cold compressive dressings reduce morphine consumption after unicondylar arthroplasty .
Cryo/Cuff Compared to Epidural Anesthesia After Knee Unicompartmental Arthroplasty: A Prospective, Randomized, and Controlled Study of 60 Patients With a 6-Week Follow-Up
J Arthroplasty. 2005 Apr;20(3):316-21Sixty patients (61 knees) undergoing unicondylar knee arthroplasty were randomized to receive cold compressive dressings (Cryo/Cuff), epidural anesthesia (EDA), or a control treatment using only traditional analgesics as needed.
