Summary
Bilateral total hip arthroplasty (THA) mortality is low, with only 0.14% of patients dying within 90 days. This study suggests one-stage bilateral THA is safe for select healthy patients.
Area of Science:
- Orthopedic Surgery
- Perioperative Medicine
- Arthroplasty Research
Background:
- Bilateral total hip arthroplasty (THA) is often perceived to have higher perioperative mortality, though evidence is limited.
- Existing literature lacks comprehensive studies evaluating the mortality risk associated with simultaneous bilateral THA.
Purpose of the Study:
- To determine the incidence of 90-day mortality following one-stage bilateral total hip arthroplasty (THA).
- To assess the safety and perioperative risk of bilateral THA in a large patient cohort.
Main Methods:
- Retrospective analysis of a database of 707 patients undergoing one-stage bilateral THA between 1995 and 2004.
- Review of patient records to identify 90-day mortality events.
- Contacting surviving patients for additional data.
Main Results:
- One death (0.14%) occurred within 90 days of one-stage bilateral THA.
- The mortality case was attributed to a spontaneous retroperitoneal hematoma leading to multisystem failure.
- The overall 90-day mortality rate in this cohort was found to be acceptably low.
Conclusions:
- One-stage bilateral total hip arthroplasty (THA) demonstrates a low 90-day mortality rate in carefully selected, healthy, and young patients.
- The procedure can be considered safe when performed on a select patient population.
- This study provides evidence against the presumed higher mortality risk associated with bilateral THA.
