Summary
Partial two-stage exchange (PTE) is a viable treatment for infected total hip arthroplasty (THA), offering good infection control and functional outcomes with less harm than traditional methods.
Area of Science:
- Orthopedic Surgery
- Infectious Disease Management
- Arthroplasty Revision
Background:
- Total two-stage exchange (TSE) for infected total hip arthroplasty (THA) causes significant bone loss and trauma.
- Partial two-stage exchange (PTE) presents an alternative approach to managing infected THA.
Purpose of the Study:
- To evaluate the clinical outcomes of partial two-stage exchange (PTE) for infected total hip arthroplasty (THA).
- To compare the efficacy and safety of PTE against traditional TSE methods.
Main Methods:
- Retrospective analysis of 28 patients undergoing PTE for infected THA (September 2000 - June 2019).
- PTE involved preserving the femoral stem, replacing acetabular components with an antibiotic-loaded spacer, followed by reimplantation.
- Eligibility required a well-fixed femoral stem prosthesis.
Main Results:
- Overall success rate of 85.7% (24/28 patients) after an average follow-up of 4 years.
- Mean Harris hip score of 76.2 ± 11.7 at final follow-up.
- Demonstrated satisfactory infection control and functional recovery.
Conclusions:
- PTE is an acceptable option for select patients with infected THA.
- PTE achieves comparable infection control and clinical outcomes to TSE with reduced morbidity.
- PTE offers a less invasive alternative for managing infected THA.
