This unique video is part of a complete module on common orthopedic surgeries displayed in 3D animation. Knee revision surgery is a repeat procedure of total knee arthroplasty performed due to various causes which are graphically demonstrated in the module. The highlights of the module are a visually comparative depiction of radiographic images on which a surgeon decides to operate again. The animation shoes steps involved in how the surgeon removes the previously implanted artificial knee joint or prosthesis and replace it with a new one.
