Summary
One-stage bilateral total hip arthroplasty (THA) offers comparable outcomes to two-stage THA with reduced costs and shorter hospital stays. This approach is safe and effective for patients needing hip replacements in both hips.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
Background:
- Bilateral hip arthritis necessitates treatment options balancing efficacy and resource utilization.
- Uncemented bilateral total hip arthroplasty (THA) is a common procedure for managing severe hip joint disease.
Purpose of the Study:
- To compare the clinical and radiographic outcomes of 1-stage versus 2-stage uncemented bilateral total hip arthroplasty (THA).
- To evaluate complication rates, functional scores, and economic factors between the two surgical approaches.
Main Methods:
- A comparative study involving 49 patients (98 hips) undergoing 1-stage bilateral THA and 40 patients (80 hips) undergoing 2-stage bilateral THA.
- Assessment included pre- and post-operative Harris Hip Scores, radiographic evaluation for component stability and bone ingrowth, and complication tracking.
Main Results:
- No significant differences in Harris Hip Scores were observed between the 1-stage and 2-stage groups.
- Radiographic analysis showed comparable component stability and bone ingrowth in both groups, with no clear signs of loosening or osteolysis.
- While complication rates were similar, the 1-stage group demonstrated significantly reduced operative time, intraoperative blood loss, procedure cost, and hospital stay.
Conclusions:
- One-stage uncemented bilateral THA is a safe and effective alternative to the 2-stage procedure.
- The 1-stage approach offers significant advantages in terms of reduced costs and shorter hospital duration, making it a favorable option for patients with bilateral hip arthritis.
