Abstract
Accelerometer-based navigation (OrthAlign) is the first computer-assisted surgical navigation system approved for use in the setting of revision total knee arthroplasty (TKA) in the United States. The senior author has used this technology in the revision setting for several years and developed the individualized, reproducible technique. The 4 goals during revision TKA are to (1) gain adequate exposure for the safe explanation of prior implants, (2) address any resultant bone loss, (3) restore the joint line via distal femur metal augmentation, and (4) ensure adequate stability through gap-balancing techniques and increasing the constraint of the revision implants as needed. This technique guide illustrates how accelerometer-based navigation (OrthAlign) can achieve these goals in the revision TKA setting.
期刊介绍：
Arthroplasty Today is a companion journal to the Journal of Arthroplasty. The journal Arthroplasty Today brings together the clinical and scientific foundations for joint replacement of the hip and knee in an open-access, online format. Arthroplasty Today solicits manuscripts of the highest quality from all areas of scientific endeavor that relate to joint replacement or the treatment of its complications, including those dealing with patient outcomes, economic and policy issues, prosthetic design, biomechanics, biomaterials, and biologic response to arthroplasty. The journal focuses on case reports. It is the purpose of Arthroplasty Today to present material to practicing orthopaedic surgeons that will keep them abreast of developments in the field, prove useful in the care of patients, and aid in understanding the scientific foundation of this subspecialty area of joint replacement. The international members of the Editorial Board provide a worldwide perspective for the journal''s area of interest. Their participation ensures that each issue of Arthroplasty Today provides the reader with timely, peer-reviewed articles of the highest quality.
