Impact of Postoperative Acetabular Wall Index on Patient-Reported Outcomes After Transposition Osteotomy of the Acetabulum in Patients With Hip Dysplasia.

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
introductionThis study aimed to determine the effect of preoperative variables and three-dimensional acetabular correction on patient-reported outcome measures after transposition osteotomy of the acetabulum (TOA), a spherical periacetabular osteotomy.
methodsWe retrospectively reviewed 442 patients (582 hips) with hip dysplasia who underwent TOA between 1998 and 2019 and completed validated questionnaires, including the visual analog scale (VAS) for pain and satisfaction and the Hip disability and Osteoarthritis Outcome Score (HOOS). The median follow-up was 12 years. Associations between patient-reported outcome measures and preoperative variables and postoperative acetabular coverage (lateral center-edge angle, anterior wall index, and posterior wall index) were analyzed.
resultsOlder age was negatively correlated with HOOS-ADL (r = -0.26, P < 0.001) and HOOS-sports/recreation (r = -0.25, P < 0.001). Male patients reported lower median HOOS-QOL than female patients (P = 0.038). Patients with Tönnis grade 0 had higher median satisfaction-VAS than those with grade 2 (P = 0.031), and higher median HOOS-ADL, sports/recreation, and QOL subscales than those with grade 1 or 2. For postoperative anterior wall index, the deficient group had higher VAS-pain (P = 0.045) and lower HOOS-pain (P = 0.047) than the normal group. For postoperative posterior wall index, the excessive group had lower HOOS-pain than the normal group (P = 0.029).
conclusionEven in preserved hips after TOA, sagittal plane acetabular correction influenced postoperative pain, whereas age, sex, and Tönnis grade affected satisfaction, functional capacity, and QOL. These insights have implications for refining surgical indications and acetabular reorientation strategies, improving postoperative patient experience.
