Early experience using patient-specific instrumentation in opening wedge high tibial osteotomy.

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.
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
purposePatient-specific instruments (PSI) have been designed to improve the accuracy of performing opening-wedge high-tibial osteotomies (OW-HTO). This study aims to evaluate the lower limb alignment, by comparing pre-operative desired correction to post-operative achieved correction, the difference in surgical time and number of radiological exposures in OW-HTO using patient-specific instruments (PSI) versus conventional osteotomies and the specific and non-specific complications that occurred.
methodsWe performed a single-centre, retrospective, observational study, including 25 consecutive patients undergoing OW-HTO using PSI, from January 2019 to October 2020.
resultsPre-operatively, the mean hip-knee angle (HKA) was 167°, the mean tibial slope was 7.9° and the mean medial proximal tibial angle (MPTA) was 82.5°. Post-operatively, the mean HKA was 182.2° (180.1-184.7°), the tibial slope was 6.5° (4.2-12.9°) and the MPTA was 92.8° (90.6-93°). In both coronal and sagittal plane, all knees were within 2° from the planned value. The mean tourniquet time, by which the surgical time was measured, was 40 minutes and the average number of intra-operative fluoroscopic images was 10 (range: 7-14), significantly less than when using conventional techniques.
conclusionsThe use of PSI in OW-HTO allows accurate achievement of the desired correction, while shortening the OR time. The number of radiological exposures is also decreased, in comparison with the conventional osteotomies.
