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 to evaluate the accuracy of a patient-specific instrumentation (PSI) as assessed by the intraoperative use of knee navigation software during the surgical procedure.

methodsFifteen patients with primary gonarthrosis were selected for unilateral total knee arthroplasty. The first three patients were excluded from this study, as they were considered to be a warm up to set-up the procedure. All patients were operated on with a cemented posterior-stabilised prosthesis cruciate ligament-sacrificing by the same surgeon using the patient matched cutting jigs. The size of the implant, level of resection, and alignment in the coronal and sagittal planes were evaluated. An unsatisfactory result was considered an error ≥2° in both planes for each component as a possible error of 4° could result in aggravation.

resultsOn the coronal plane the mean deviation of the tibial guide from the ideal alignment was 1.2 ± 1.5 (range 0-5°) and in the sagittal plane was 3.8 ± 2.4 (range 0-7.5°). On the coronal plane the mean deviation of the femoral guide from the ideal alignment was 1.2 ± 0.6 and in the sagittal was 3.7 ± 2.

conclusionOn the basis of this preliminary experience the PSI system based only on data acquisition with A-P radiograms and RMN cannot be defined as accurate. In cases of the use of the custom made cutting jigs it is recommended to perform an accurate control of the alignment before making the cuts, for any step of the procedure. LEVEL OF EVIDENCE: II.
