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

purposeWhether to resurface the patella during a primary total knee arthroplasty remains a controversial issue. The aim of this study was to determine the advantages and disadvantages of patellar resurfacing during total knee arthroplasty for osteoarthritis through an evaluation of the current literature.

methodsA meta-analysis of randomized controlled trials comparing patellar resurfacing with nonresurfacing during total knee arthroplasties was performed. The focus of this analysis was on outcomes of reoperation, anterior knee pain and knee scores.

resultsTen trials assessing 1,003 knees were eligible. The absolute risk of reoperation was reduced by 4% (95% confidence interval, 1-7%) in the patellar resurfacing arm (between-study heterogeneity, P = 0.06, I (2) = 45%), implying that one would have to resurface 25 patellae (95% confidence interval, 14-100 patellae) in order to prevent one reoperation. Only seven trials provided adequate data of anterior knee pain for a quantitative synthesis. On the basis of those seven trials, there was no difference between the two groups in terms of anterior knee pain. Anterior knee pain after total knee arthroplasty could have multiple etiologies such as surgical factors and nonresurfaced patella is not the sole cause of this problem.

conclusionThe available evidence indicates that patellar resurfacing reduce the risk of reoperation after total knee arthroplasty for osteoarthritis. Not resurfacing the patella might be considered a reasonable option, but patients must accept the increased risk of reoperation for which the quantitative evidence-based synthesis is mild. Based on the evidence provided by this study and those previously published ones, the authors do not now resurface the patella as a matter of routine for patients having a primary total knee arthroplasty for osteoarthritis.
