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

backgroundManagement of the patella during total knee arthroplasty is a matter of constant debate. Numerous studies have assessed and compared the mechanical and clinical results of total knee arthroplasty with native as well as resurfaced patellae. However, the consensus has not been reached yet on this subject. This study aims to compare the outcome between patella resurfaced (PR) and non-resurfaced patellae (NPR) after a follow-up of minimum 10 years following total knee arthroplasty. MATERIALS AND

methodsThis is a retrospective study including 63 subjects (103 knees) who had undergone total knee arthroplasty with a follow-up of 10-14 years. In this study, we evaluated the knees implanted with either press fit condylar (PFC) sigma (Depuy, Johnson & Johnson) or Nexgen (CR flex/LPS flex) (Zimmer, Warsaw, Indiana, USA) implants. Whether to perform patella resurfacing or not and choice of implants as well as implant design (posterior stabilized/cruciate retaining) was surgeons' preference. At final follow-up, clinical and functional outcome was assessed using Knee Society Scores (KSS), and comparison of difference between pre-op scores and scores at final follow-up among resurfaced versus non-resurfaced patellae groups was carried out. Patello-femoral function was assessed at final follow-up using Feller's score and the results were compared between resurfaced and non-resurfaced patellae.

resultsThe mean follow-up was 140 months (range 124-168 months). There were 62 knees with their patella resurfaced and 41 knees with non-resurfaced patellae There was no significant difference in the mean pre-op Knee Society Scores between PR (46.29 ± 5.17) and NPR (47.34 ± 5.95),

conclusionAfter a minimum follow-up of 10 years, there were no differences in clinical results; however, the knee function score and patello-femoral function scoring was found to be significantly higher with patella resurfacing and it was persistent across all the subgroups we had included in the study-posterior stabilized/cruciate retaining or between implants made by two different manufacturers.
