How to Drape a C-Arm

When intraoperative imaging is needed, a mobile x-ray machine must be used by a radiologic technologist (RT) to take the image. A C-arm portable imaging machine, so called because its shape resembles the letter “C”, is widely used in contemporary surgical and interventional procedures for this purpose, and its proper draping is essential for maintaining sterile field integrity. This educational video demonstrates how to receive a C-arm drape onto the sterile field, how to prepare it for use, and how to place and secure it around the C-arm using sterile technique to protect patient safety. This video was filmed in an academic setting and is intended for perioperative trainees and staff.
Posterior Cruciate-Retaining Total Knee Arthroplasty

Abstract: Total knee arthroplasty has evolved into a very successful procedure to relieve pain and restore function in the arthritic knee with advanced structural damage. Optimal results are dependent on the restoration of alignment and ligament stability. Operative techniques involve either preservation of the posterior cruciate ligament or substitution of its function through increased prosthetic constraint. The vast majority of knees do not require cruciate substitution to establish appropriate stability and function. This video outlines the operative technique used by the author for posterior cruciate-retaining total knee arthroplasty in a patient with a preoperative varus deformity.
