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

introductionOver the last years, the design of implants, the surgical approaches, and diagnostic tools changed in primary and revision of total hip arthroplasty. A knowledge of the different causes for revision after total hip arthroplasty is essential to avoid complications and failures. The purpose of this study was to determine trends of the etiology of implant failures over the last years by analyzing indications of revision hip arthroplasty.

methodsAll the patients who performed revision hip arthroplasties in our institution between 2001 and 2015 were reviewed retrospectively. Patient demographics, the indication for revision surgery as well as the procedure were assessed. Descriptive statistical analyses and association analyses were performed.

resultsWithin our collective of 3450 revision hip arthroplasties, a total of 20 different indications were identified and categorized. Overall, 80.8% of the revisions were categorized as aseptic, 19.2% as septic implant failures. Some recently debated diagnoses like low-grade infection showed a high increase in incidence, whereas classic failure mechanisms like polyethylene wear showed a decrease over the time. In addition, the data revealed that cup loosening caused more revision surgeries than stem loosening.

conclusionThis study successfully updated the current knowledge of different failure mechanisms in revision hip arthroplasties. The data proved that cup loosening was the most common failure mechanism in older patients, while in young patients, septic complications showed a high incidence. Probably, due to improved diagnostic tools, the percentage of infection in revision hip arthroplasty increased over the years.
