Summary
One-stage total hip arthroplasty (THA) for bilateral hip disease is as safe as staged procedures. A meta-analysis found no significant difference in major complications, supporting the safety of one-stage bilateral THA.
Area of Science:
- Orthopedic Surgery
- Medical Technology
- Clinical Research
Background:
- The safety of one-stage versus two-stage total hip arthroplasty (THA) for patients with bilateral hip disease remains a subject of debate.
- Previous studies have yielded conflicting results regarding complication rates.
Purpose of the Study:
- To conduct a meta-analysis comparing the safety of one-stage and two-stage THA for bilateral hip disease.
- To evaluate the incidence of major complications in both surgical approaches.
Main Methods:
- A meta-analysis was performed on 1460 identified studies.
- Five prospective studies meeting inclusion criteria were analyzed, involving 579 patients undergoing two-stage THA and 334 patients undergoing one-stage surgery.
- Data heterogeneity was assessed (I2 =0%), permitting data pooling.
Main Results:
- The meta-analysis revealed no statistically significant difference in the incidence of major complications between one-stage and two-stage bilateral THA.
- The odds ratio for major complications was 0.72 (95% CI: 0.45-1.15).
Conclusions:
- One-stage bilateral total hip arthroplasty can be considered a safe surgical option.
- The findings suggest that surgeons can confidently consider one-stage bilateral THA for appropriate patients, potentially offering benefits in terms of efficiency and recovery.
