The Addition of Navigation Technology to the Femur-First Approach in Anterior Total Hip Arthroplasty Improves Leg Length Restoration.

Background: The addition of computer navigation (CN) technology in direct anterior approach (DAA) total hip arthroplasty (THA) has the potential to improve restoration of hip offset and leg length. In this investigation, we examine the effect of one fluoroscopic-based CN system on biomechanical parameters in DAA THA with femur-first (FF) workflow.

Methods: A retrospective review was performed on 235 primary DAA FF THA cases, with 100 CN cases and 135 in the conventional fluoroscopic overlay (FO) group.

A Workflow Change in Anterior Approach Total Hip Arthroplasty Leads to Improved Accuracy of Biomechanical Reconstruction Without Increased Risk of Complications.

Background: During anterior approach total hip arthroplasty (THA), the femur may be an impediment for acetabular access, pushing reamers proximally and consequently altering the hip center. In an effort to address this, the senior author changed the surgical workflow from acetabulum first (AF) to femur first (FF). The objective of this study was to compare the precision of biomechanical hip reconstruction and clinical outcomes between the FF and AF techniques.

The Actis and Corail Femoral Stems Provide for Similar Clinical and Radiographic Outcomes in Total Hip Arthroplasty.

Background: The introduction of new devices for total hip arthroplasty (THA) offers surgeons the ability to address deficits in the portfolio. However, once introduced, data regarding the performance of devices is not publicly available until their use is widespread.

Purpose/questions: The objective of this study was to compare the clinical and radiographic performance, including patient reported outcomes and radiographic evidence of osseointegration, subsidence, and stress shielding, of the newer Actis femoral component to the Corail stem (DePuy Synthes, Warsaw, IN, USA), which has an extensive clinical history.
