Abstract: Total hip arthroplasty is an increasingly common procedure used to address degenerative changes in the hip joint due to osteoarthritis. Although generally associated with good results, among the challenges associated with hip arthroplasty are accurate measurement of
biomechanical parameters such as leg length, offset, and cup position, discrepancies of which can
lead to significant long-term consequences such as pain, instability, neurological deficits, dislocation, and revision surgery, as well as patient dissatisfaction and, increasingly, litigation. Current methods of managing these parameters are limited, with manual methods such as outriggers or calipers being used to monitor leg length; however, these are susceptible to small intraoperative changes in patient position and are therefore inaccurate. Computer-assisted navigation, while offering improved accuracy, is expensive and cumbersome, in addition to adding significantly to procedural time. To address the technological gap in hip arthroplasty, a new intraoperative navigation tool Intellijoint HIP has been developed. This innovative, 3D mini-optical navigation tool provides real-time, intraoperative data on leg length, offset, and cup position and
allows for improved accuracy and precision in component selection and alignment. Benchtop
and simulated clinical use testing have demonstrated excellent accuracy, with the navigation
tool able to measure leg length and offset to within 1 mm and cup position to within 1 in
both anteversion and inclination. This study describes the indications, procedural technique, and
early accuracy results of the Intellijoint HIP surgical tool, which offers an accurate and easyto-
use option for hip surgeons to manage leg length, offset, and cup position intraoperatively.
