1 · What the graph read from it

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.

2 · The registry

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

objectivesTotal hip arthroplasty (THA) is the gold standard for treating Crowe IV developmental dysplasia of the hip (DDH). However, its long-term effects on lower limb alignment, gait biomechanics, and plantar force in these patients remain underexplored, which is discussed in this article.

methodsWe conducted a retrospective cohort study that included 43 DDH Crowe IV patients who underwent THA between February 2008 and October 2019 and a control group of 43 matched healthy volunteers. Postoperative functional outcomes and quality of life were assessed using the Harris Hip Score, KOOS, AOFAS, and WOMAC scores. Lower limb alignment parameters (MAD, HKA, aTFA, mLDFA, mMPTA, and FO), knee alignment (HMFC, HLFC), and ankle alignment (mLDTA, FACO, and TT) were measured preoperatively, postoperatively, and at follow-up. Gait analysis and plantar force measurements were performed at the final follow-up.

resultsWith an average follow-up of 10.2 years, patients showed significant improvement in functional and quality of life scores compared to pre-surgery. Preoperatively, all patients had knee valgus and ankle varus on the affected side. After THA, most parameters showed reduced valgus alignment, except for HKA and HLFC. On the unaffected side, MAD, aTFA, and HKA indicated preoperative valgus, which was fully corrected post-THA. Gait analysis revealed restricted lower limb motion and abnormal plantar force distribution that persisted postoperatively in Crowe IV DDH patients.

conclusionsTHA partially corrected abnormal lower limb alignment, gait parameters, and plantar force distribution in DDH Crowe IV patients over long-term follow-up.
