Preoperative Patellofemoral Malalignment Worsened the Outcome of Patients after Total Knee Arthroplasty.
Observational study in The journal of knee surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
The impact of preoperative patellofemoral malalignment (PFM) on the prognosis of patients who underwent total knee arthroplasty (TKA) remains unknown. This study aimed to explore the effect of preoperative PFM on the prognosis of patients who underwent TKA. This retrospective observational study included patients who underwent TKA at the Second Hospital Affiliated to Fujian Medical University between February 2018 and July 2020. The primary outcome measure was the Hospital for Special Surgery Knee-Rating Scale (HSS) score. The secondary outcomes included postoperative radiographic parameters (X-rays) and the occurrence of complications. A total of 94 patients (107 knees) who underwent TKA were included in the study. Of these, 37 knees had PFM and 70 had normal patellofemoral alignment (PFA). Patients with preoperative PFM showed a change in patellar outward displacement from 7.01 ± 3.91 mm preoperatively to -0.31 ± 2.86 mm postoperatively (
