ANALYSIS OF THE SURVIVAL RATE OF NATIONAL HIP PROSTHESIS IMPLANTS IN AN ORTHOPEDIC CENTER IN PARANÁ

Abstract

Objective: To evaluate the survival time of domestically manufactured hip prosthesis implants at the Orthopedics and Traumatology service of a reference hospital in Cascavel-PR, Brazil. The aim is to verify the revision rate and investigate whether the reason for revision is related to the domestic origin of the implant, comparing its survival with data from international literature. Methods: This is a retrospective, descriptive, and quantitative study. Data were collected from the medical records of patients who underwent total hip arthroplasty with domestically manufactured implants at a reference hospital in orthopedics and traumatology in western Paraná, who had a minimum follow-up of 10 years, analyzing the need for revision of the domestic prostheses and comparing these data with those from international literature. Results: Medical records of 200 patients were analyzed, of which 106 patients were excluded for not meeting the criterion of 10 years or more of follow-up. Of the patients who met the selection criteria, 86.17% remained with the primary prosthesis, even after the minimum period of 10 years. Conclusion: Domestically manufactured hip prostheses demonstrate adequate clinical and functional efficacy, potentially representing a cost-effective alternative when compared to imported implants, provided that they are associated with infection prevention protocols and adequate postoperative follow-up.
