Abstract

This is a prospective data collection across seven centers in a non-randomized, post- market study where an additive manufactured cementless acetabular shell was used in primary total hip arthroplasty. There was a total of 254 hips/246 patients across seven centers. Clinical outcomes including all-cause survivorship, the Harris Hip Score (HHS), Lower Extremity Activity Scale (LEAS), Veterans Rand 12 (VR-12), EuroQol 5D (EQ- 5D) and radiographs were collected pre- and postoperatively. Radiographs were analyzed for presence of radiolucencies, migration and overall cup stability. All-cause survival rate was 99.61% and there were no reported radiolucencies greater than 2mm for any zone. There was a reduction in radiolucencies from the 6-week to 1-year postoperative timeframe. All cups reviewed at 1-year were stable with no radiolucencies in 96% of hips. These early results demonstrate the favorable properties of this shell and the use of additive manufacturing in orthopaedic surgery.
