THA With and Without Computer Navigation

The Use of Intraoperative Fluoroscopic Computer Navigation on Hip Arthroplasty Component Position

The goal of this observational study is to compare postoperative results between patients who had total hip arthroplasty (THA) with and without the use of a computer navigation program. The main questions this study aims to answer are:

• Can using computer navigation produce better THA implant placement?
• Can using computer navigation make surgery more efficient?

Participant data collected include their postoperative x-rays and total operative time.

The goal of this retrospective study is to compare implant placement and operative time of patients who underwent direct anterior total hip arthroplasty with and without the use of a computer navigation program. X-rays are used to measure acetabular cup orientation, leg length discrepancy, and total operative time.

Inclusion Criteria:

• Patients who underwent Direct Anterior (DA) THA with the principal investigator between August 2018 and February 2020 and received ACTIS stem and PINNACLE cup with or without computer navigation

Exclusion Criteria:

• Patients who underwent subsequent revision THA, conversion arthroplasty, hybrid procedures, experienced native or postoperative dislocations, and missing or inadequate radiographs at time of data collection.
