This video demonstrates the surgical procedure for a total knee arthroplasty using a mechanical alignment technique. It details the steps involved, from patient positioning and incision to bone preparation, component trial, final implantation, and wound closure, emphasizing the importance of accurate alignment for prosthetic function.
The goal of using mechanical alignment in total knee arthroplasty, as described in the video, is to align the prosthesis along the mechanical axis of the limb, which is a straight line running from the center of the hip joint through the center of the knee to the center of the ankle joint. This line represents the limb's weight-bearing line, and the objective is to position the prosthesis on the femur and tibia perpendicular to this line.
