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

purposeRecently, ultra-congruent (UC) inserts have shown successful outcomes following total knee arthroplasty (TKA). It was hypothesized that patients in the UC group would not show significantly different in vivo stability or functional outcomes from those in the cruciate-retaining (CR) group.

methodsThe prospective study enrolled patients who had been treated with either CR or UC TKAs (38 cases in each group), after a minimum 3-year follow-up. The same surgical technique was used with the same femoral components in both groups except for the polyethylene inserts (CR or UC). The clinical outcome measures were knee range of motion (ROM), Hospital for Special Surgery (HSS) score, Knee Society (KS) score, and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) subscale score. The mediolateral laxity at full extension and anteroposterior laxity at 90° flexion were measured in stress radiographs and compared between the two groups.

resultsBoth the CR and UC groups showed significant improvements in post-operative ROM, HSS, KS, and WOMAC scores without inter-group differences between two groups. Moreover, there were no differences in mediolateral or anteroposterior laxity between the two groups (p > 0.05).

conclusionTKA with posterior cruciate ligament (PCL) resection using the UC design showed comparable functional outcomes with those of CR TKA and provided similar in vivo stability. Therefore, UC inserts can be a good option in TKA without bony box cut when the PCL is damaged during an operation. LEVEL OF EVIDENCE: II.
