Functional, Radiological Results and Quality of Life after Primary Total Hip Arthroplasty

Abstract

Introduction: The objective of this work was to evaluate the clinical and radiological results; and the quality of life of patients with THA at final follow-up. Patients and Method: This was a prospective, multicenter, multi-operator study, which was carried out in patients with THA, between January 1, 2014 and December 31, 2022. The clinical evaluation was carried out with the PMA, Devane and WOMAC activity scores. Radiologically, the analysis focused on the inclination of the cup, the peri-prosthetic lines and the bony integration of the implants. Results: 85 patients were re-evaluated out of 145; 60 were lost to follow-up including 16 due to death, the average follow-up was 5.85 years. The average age was 51.81 years (39-85). The functional scores were generally satisfactory at the last follow-up with a mean PMA, Devane and WOMAC score of 15.8 respectively; 2 and 76.54 and a rate of resumption of sexual intercourse after THA of 54.11%. The mechanical complications were: 8 revisions for prosthetic loosening, 4 wear and osteolysis, 02 periprosthetic margins. The patients were much more optimistic than the surgeon: 94.73% of the patients judged their results to be excellent or good while the surgeon only accepted 85.96%. Conclusion: Degenerative hip joint pathologies seem to be increasing due to the incidence of complications of sickle cell disease. The need for joint replacement is growing despite the still expensive cost. At the last follow-up, the overall results are satisfactory and a rate of resumption of sexual intercourse after THA of 54.11%. Chronic pain and muscle atrophy have had a significant impact on quality of life and sexual activity. Our study confirms the medium-term reliability of dual mobility with a survival rate of 90.60%. These results must be tempered because of the occurrence of long-term complications, linked to the risk of dual mobility in young subjects.
