THA With and Without Computer Navigation

Completed

• Conditions: Hip Osteoarthritis; Avascular Necrosis of Hip
• Interventions: Procedure: Intraoperative Fluoroscopic Computer Navigation

• Registration Number: NCT05871827
• Lead Sponsor: Southeast Orthopedic Specialists

Brief Summary

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.

Detailed Description

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.
