Comparative Randomized Study of The Outcome of Single versus Two Stage Revision for Prosthetic Hip Infection
Bibliographic record
Abstract
Background: Continuous debates persist on the gold standard approach for managing periprosthetic joint infection (PJI) following total hip arthroplasty (THA). Objective: This study aimed to compare the outcomes of single-stage revision versus two-stage revision for PJI after THA. Patients and methods: 40 patients were included in this study with minimum duration of follow-up of 12 months. The patients were divided into two equal groups. Group A (n=20): Single-stage revision THA. Group B (n=20): Two-stage revision THA. Infection eradication, Harris hip score (HHS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, radiological evaluation and complications were compared between the two groups. Results: There was one case of reinfection, which occurred in group B. In group A, the mean HHS was 91.70 ± 3.79 and mean WOMAC score 9.95 ± 3.78. In group B, scores were lower with mean HHS of 88.85 ± 5.31 and mean WOMAC score 15.90 ± 7.32 and complication rates were higher. There were no significant differences in radiographic outcome between the groups. Conclusion: The single-stage revision was associated with several advantages, including shorter hospital stays, reduced duration of antibiotic therapy and superior functional outcomes as well as more efficient recovery.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
