Onsets of complications and revisions are not increased after simultaneous bilateral unicompartmental knee arthroplasty in comparison with unilateral procedures.

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
purposeThe advantages of simultaneous bilateral procedures in joint arthroplasty have been widely described for in total joint replacements of both the hip and the knee. In contrast, unicompartmental knee arthroplasties, despite their effectiveness in pain relieving and functional improvement, are underinvestigated in these terms. The purpose of this study is to assess the possible benefits and risks of bilateral simultaneous knee replacements, in comparison with unilateral procedures.
methodsA total of 567 surgery reports of bilateral simultaneous (220) or unilateral (347) unicompartmental knee arthroplasties were analysed to collect study parameters. Information like the onset of complications and need for revisions were recorded by phone interview (at least two years after surgery). All surgeries were performed by the same orthopaedic surgeon, assisted by the same anesthesiologist.
resultsComplication and revision rates, as well as the length of hospital stay were similar between the two study groups, while blood and haemoglobin losses, and consequently the use of transfusion of allogeneic and autologous blood units, were higher in the simultaneous bilateral group.
conclusionsSimultaneous bilateral unicompartmental knee arthroplasties could significantly reduce, if both joints are affected, the length of hospital stay and, therefore, patient management costs. At the same time, they do not lead to more frequent revisions or complications. The higher transfusion of allogeneic blood units could be reduced to unilateral surgery levels by the application of currently available protocols of autologous blood reinfusion.
