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

purposeThe aim of this study is the investigation of the clinical results after third generation autologous chondrocyte implantation in the knee in a follow-up over three years post-operation. Our primary focus is on the effects of this procedure on children and adolescent patients as there is a lack of knowledge regarding the clinical outcomes in children/adolescents in particular when compared with adults.

methodsA total of 40 patients (43 defects) <20 years with cartilage defects of the knee were treated with third generation ACI (Novocart® 3D). These defects were caused by osteochondritis dissecans (n = 13), acute trauma (<12 months) (n = 9), old trauma (>12 months) (n = 5) or unknown pathology (n = 13). The mean defect size was 5.2 cm

resultsAll patients showed significantly better clinical results compared with the pre-operative findings in the follow-up over three years. We observed significantly better results in the IKDC score and VAS during the whole postoperative follow-up in children and adolescents after six, 12, 24 and 36 months compared with the adult control group. The IKDC score improved from 46.5 preoperative to 77.5 (+31) after three years in children and adolescents. Similarly, significantly lower stress pain after six months and one, two and three years was found in this group.

conclusionThis study showed that third generation autologous chondrocyte implantation is a suitable method for the treatment of full cartilage defects in children and adolescents.
