Does travel distance influence short-term outcome after periacetabular osteotomy?-A cohort study.

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: Periacetabular osteotomy (PAO) is an established joint-preserving procedure for the treatment of developmental dysplasia of the hip (DDH). As PAO is typically concentrated in specialized centres, many patients travel considerable distances for treatment. The purpose of this study was to evaluate the influence of travel distance on short-term outcomes following PAO. Methods: This prospective registry study included 296 hips undergoing PAO for DDH between January 2022 and May 2025 by a single experienced surgeon. Travel distance was determined using driving distance, and hips were stratified into two groups: ≤80.5 and >80.5 km from the treating centre. Radiographic parameters, patient-reported outcome measures (PROMs) and rates of achieving the Patient Acceptable Symptom State (PASS) and Minimal Clinically Important Difference (MCID) for the modified Harris Hip Score (mHHS) and international Hip Outcome Tool-12 (iHOT-12) were analysed. Results: A total of 126 hips (43%) resided ≤80.5 km and 170 hips (57%) >80.5 km from the treating centre. Hips of patients travelling longer distances demonstrated a lower preoperative lateral centre-edge angle ( Conclusion: Travel distance to a specialized hip preservation centre does not influence short-term outcomes following PAO. Comparable functional outcomes and complication rates can be achieved irrespective of travel distance, supporting the feasibility of centralized PAO care in specialized high-volume centres. Level of Evidence: Level III.
