CT-based navigation for total hip arthroplasty: a meta-analysis

European journal of medical research, vol. 28, pp. 443

Abstract

INTRODUCTION: Computer tomography (CT) based navigation is considered by some authors as an advance in total hip arthroplasty (THA). A meta-analysis was conducted to compare CT based versus conventional THA in terms of surgical duration of the procedure, leg length difference, acetabular cup position, and rate of dislocation. MATERIAL AND METHODS: The present study was conducted according to the PRISMA 2020. In December 2022, the following databases were accessed: PubMed, Web of Science, Google Scholar, Embase with no time constrain. All the clinical studies comparing CT based navigation versus the conventional THA were accessed. RESULTS: . There was between studies comparability at baseline in terms of age, BMI, pain score, Harris hip score, leg length discrepancy (P > 0.1). The navigated group demonstrated lower leg length discrepancy (P = 0.02), and lower degrees of cup anteversion (P = 0.002). Similarity was found in cup inclination (P = 0.98), surgical duration (P = 0.3), and the rate of dislocation (P = 0.6). CONCLUSION: CT guided THA may have the potential to increase the accuracy of acetabular positioning and reduce the leg length discrepancy. Current evidence is very limited and heterogeneous, and no recommendations can be inferred. Further investigations are required to definitely clarify the role of CT based THA in current practice.
