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

backgroundTotal knee arthroplasty (TKA) is a widely used treatment for advanced knee osteoarthritis; however, the incidence of failures requiring revision surgery is increasing. Identifying the causes of TKA failure and assessing the outcomes of revision procedures are essential for improving patient care. We hypothesized that infection and aseptic loosening are the primary causes of TKA failure and that revision TKA (rTKA) significantly enhances functional outcomes.

aimTo examine the primary causes of TKA failure and evaluate the functional outcomes following rTKA.

methodsThis descriptive study was conducted at the Department of Orthopedic Surgery, Civil Hospital, Bahawalpur, from April to September 2024. A total of 118 patients undergoing rTKA for failed primary TKA were included. Data on demographics, causes of failure, and surgical details were collected. Functional outcomes were evaluated using the Knee Society Score and Visual Analog Scale before and six months after surgery. Statistical analysis was performed using SPSS version 25.0, with statistical significance set at

resultsThe leading causes of TKA failure were infection (45.8%), aseptic loosening (44.1%), and periprosthetic fractures (10.2%). The rTKA significantly improved knee function, with the mean Knee Society Score increasing from 39.43 ± 6.18 to 78.91 ± 6.17 (

conclusionInfection and aseptic loosening are the predominant causes of TKA failure. The rTKA effectively enhances knee function and alleviates pain, offering significant benefits to patients.
