A Cadaveric Study to Assess the Accuracy of Computer-Assisted Surgery in Locating the Hip Center During Total Knee Arthroplasty
Authors: Frederic Picard, Francois Leitner, Alberto Gregori, Philippe Martin, The Journal of Arthroplasty, Vol 22, no 4, March 2007, DOI: 10.1016/j.arth.2006.04.027
Computer-assisted technology allows the accurate location of inaccessible landmarks such as the center of the hip in total hip arthroplasty. Using 7 fresh normal cadaveric hips, we conducted 2 studies. The first study compared iliac (A) vs no iliac (B) tracking. The second study assessed the reliability of the hip center acquisition using the range of hip motion during manipulation. The first study revealed no statistical difference between the 2 techniques A (mean, 0.67; SD, 0.15) and B (mean, 0.66; SD, 0.32) used to locate the center of the hip. In the second study, a range of motion less than 10° negatively affected accuracy. Using this technology, without an iliac tracker, allows accurate and precise determination of the center of the hip.
