Success Rate of Partial Two-Stage Exchange Arthroplasty for Late Chronic Periprosthetic Joint Infections in Total Hip Arthroplasty: A Meta-Analysis.
Article in Hip & pelvis, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Purpose: Periprosthetic joint infections (PJIs) resulting from total hip arthroplasty (THA) pose significant challenges. Partial two-stage exchange arthroplasty (TSEA) retains either the femoral stem or acetabular cup by preserving bone stock and soft tissue and offers a potential alternative to total TSEA. Our meta-analysis evaluated the pooled success rate of partial TSEA in treating late chronic PJIs in THA. Our study also focused on the outcomes associated with retained prosthetic implant (stem or cup) and the type of prior surgery (primary vs. revision arthroplasty) performed. Materials and Methods: We analyzed data from 355 hips of patients with PJI following THA across 11 studies using a random-effects model to estimate the success rate of partial TSEA and spacer dislocation that occurs during the interval between the first and second stages of partial TSEA. The heterogeneity between the subgroups was also calculated. Results: The overall pooled success rate of partial TSEA in the study cohort was 87% (95% confidence interval [CI] 83-91). Lacking statistical significance ( Conclusion: Partial TSEA achieves high success rates comparable to those of total TSEA. Although revision arthroplasty cases carry a high risk of recurrence, partial TSEA remains a viable, tailored treatment option with a low complication rate.
