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

purposePes anserinus pain syndrome (PAPS) is a well-described condition in the native knee; however, its incidence after total knee arthroplasty (TKA) is unknown. This study aimed to determine the incidence of PAPS after primary TKA, identify potential risk factors, and assess its response to treatment. Few case reports have been published until now; to our knowledge, ours is the first study assessing the incidence and predictors of post-TKA PAPS.

methodsA total of 389 primary TKAs performed for degenerative varus knee at a single institution by the same surgeon were analyzed. We recorded demographic variables, medical comorbidities, and clinical, radiographic, and surgical data. Specific predictors of interest were compared between post-TKA PAPS and controls.

resultsThe incidence was 5.6% (22/389). On univariate analysis, female sex (p = 0.03), body mass index (BMI) (41.3% ± 7.9; p < 0.001), and absence of pes anserinus release (p = 0.04) were significant predictors. On multivariable regression analysis, only BMI was a significant independent risk factor (p = 0.01). All patients were treated non-operatively; 81.8% responded to nonsteroidal anti-inflammatory drug-physical therapy program and 18.2% required an additional local steroid injection.

conclusionPAPS occurs after TKA; the incidence was found to be 5.6%. BMI seems to be an independent risk factor. It is a benign condition and can be effectively treated conservatively in most cases.
