From Measured Accuracy to Patient Outcome: Navigation in Total Hip Arthroplasty and Molecular Diagnosis of Periprosthetic Joint Infection: A Narrative Review

Background

Total hip arthroplasty (THA) and the diagnosis of periprosthetic joint infection (PJI) have each acquired a technology that measures with high precision: intraoperative navigation, which reports component position to within a few degrees, and molecular methods, which identify the infecting organism and the host response at genomic resolution.
