Precision and accuracy of imageless navigation versus freehand implantation of total hip arthroplasty: A systematic review and meta‐analysis

Abstract

Background: Total hip arthroplasty (THA) is named the most successful surgical procedure of

Portable Accelerometer-Based Navigation System for Cup Placement of Total Hip Arthroplasty: A Prospective, Randomized, Controlled Study

“…And values of deviation for cup anteversion were between 3.4 and 5.5 in the navigation group, and between 6.6 and 13.7 in the conventional group. The values of deviation for cup abduction and anteversion in this study were similar or slightly larger than the values in the meta-analysis reported by Snijders et al [18].…”

In vivo kinematic analysis of patients with robotic‐assisted total hip arthroplasty during gait at 1‐year follow‐up

“…As no differences between robot-assisted and freehand THA were observed in this study, future work may also consider the use of computer navigation systems as these are less costintensive, when compared with robotic arm-assisted THA, and several studies in the literature have demonstrated that computer navigation systems improve component placement. [30][31][32][33] In conclusion, our study suggests that the robot-assisted THA has the potential utility in restoring the native hip geometry with higher accuracy and repeatability than the freehand THA technique. However, as the magnitude of asymmetry in kinematic parameters in all three anatomical planes was comparable between robot-assisted and freehand THA patient groups, this study suggests that, while both robot-assisted and freehand THA have the potential to improve gait symmetry, no differences in gait symmetry at 1-year follow-up existed between both groups.…”

“…Lastly, as in vivo kinematics are influenced by multiple factors including patient, implant, and surgical factors, and the sample size for the freehand THA group is small, further study is needed to further elucidate the influences of these parameters on the robotic arm–assisted THA procedure in terms of in vivo kinematics. As no differences between robot‐assisted and freehand THA were observed in this study, future work may also consider the use of computer navigation systems as these are less cost‐intensive, when compared with robotic arm–assisted THA, and several studies in the literature have demonstrated that computer navigation systems improve component placement …”

Mixed Reality-Based Simulator for Training on Imageless Navigation Skills in Total Hip Replacement Procedures

“…During the study they were asked to set up the surgical scene, adjust the infrared camera field of view and acquire a total of 27 points which were displayed one after another and distributed between pelvic anatomical landmarks, the surface of the acetabulum and femoral landmarks. These high amounts of points enabled learning through repetition, since the simulator would only allow the user to progress in the experience as a new point was acquired, visual and audio feedback were displayed after a successful landmark acquisition, allowing users to 1 Plane that divides the body into front and back sections.…”
