Gait kinetics before and after total hip arthroplasty in people with unilateral hip osteoarthritis.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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
backgroundTotal hip arthroplasty (THA) is a common intervention for end-stage osteoarthritis (OA) that improves gait kinetics. However, full restoration of mobility through THA remains elusive. Limited studies have examined changes in hip kinetics throughout the entire stance phase. In this study, we explored the differences in hip moment and power between preoperative and postoperative states in unilateral hip OA and compared these patients with healthy controls.
methodsA secondary analysis was conducted using a publicly available dataset. A total of 69 healthy controls and 67 participants with a history of THA for whom preoperative and postoperative data were available for analysis were included in the study. Motion capture data obtained using the Plug-in Gait marker set was analyzed and modeled in Visual3D. Statistical parametric mapping (SPM) paired t tests were used to determine the differences in hip moment and power during the stance phase between preoperative and postoperative states. Independent-samples t tests were conducted to compare these metrics in healthy controls and both preoperative and postoperative groups. SPM regression was used to analyse the correlation between changes in walking speed and hip kinetics.
resultsSignificant changes in hip sagittal moment (0.0-4.3% stance phase, P = 0.037; 66.7-100.0% stance phase, P < 0.001), frontal moment (9.9-38.7% stance phase, P < 0.001; 55.2-93.7% stance phase, P < 0.001) and hip power (50.8-70.8% stance phase, P < 0.001; 84.2-100.0% stance phase, P < 0.001) were observed between the preoperative and postoperative participants, and a minor difference was noted in the total difference duration between the postoperative participants and healthy controls. The postoperative participants experienced hip kinetic deficits, and a significant association was observed between hip kinetics and changes in walking speed.
conclusionThe hip kinetics of patients gradually normalise by 6 months after THA. Specific exercise programmes may be required to improve the specific gait patterns deficits of patients undergoing THA.
