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

backgroundThe lifetime risk of developing symptomatic knee osteoarthritis (OA) is estimated to be 45%, with up to two thirds of patients presenting with bilateral knee symptoms. Patients presenting with end stage bilateral knee OA may benefit from single anaesthetic bilateral total knee replacement (SABTKR). Our study aim was to compare the outcomes of SABTKR with unilateral total knee arthroplasty (TKA) in a single surgeon series over a 20 year period.

methodsWe performed a retrospective review of a single surgeon's data from the New Zealand Joint Registry (NZJR) over a 20-year period from January 1999 to December 2018. This review reports on patient demographics, functional outcomes, revision rates and mortality rates.

results1225 total knee replacements were performed by the senior author (995 TKAs and 115 patients underwent SABTKRs) over the 20 year period reviewed. The mean ages of the TKA and SABTKR groups were 67.7 and 66.7 years, respectively. There was 16.9% mortality rate for the TKA group versus 7.8% in SABTKR group. There were no revisions in the SABTKR group versus 17 revisions in the TKA group representing a revision rate of 0.23/100 component years which can be viewed against a 20 year revision rate of 0.48/100 component years (p < 0.05) for all comers in the NZJR.

conclusionThis NZJR study demonstrates excellent medium term survival outcomes for selected patients having simultaneous bilateral total knee replacements.
