Opening wedge high tibial osteotomy using patient-specific instruments and custom-made plates results in accurate correction and improved clinical outcome measures at 1-year follow-up.

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
Purpose: Achieving high accuracy is a primary goal in opening wedge high tibial osteotomy (HTO). However, literature on the combined use of patient-specific instruments (PSI) and patient-specific plates (PSP) remains limited. This study investigates the accuracy and clinical results of the combined use of a novel PSI and PSP system. Methods: All medial open-wedge HTO using the PSI and PSP system from Medacta (Medacta, Castel San Pietro, Switzerland) between November 2021 and April 2023 at our institution were included. The hip-knee-ankle angle (HKA) and the posterior tibial slope (PTS) were measured preoperatively, and at 4.5 months and 1 year postoperatively, to assess surgical accuracy. The knee society score (KSS) was collected preoperatively and at 1 year postoperatively. Results: Fourteen knees from 14 patients (6 females, 8 males) were included. Accuracy for HKA correction at 1-year follow-up was 1.9 ± 1.4°, whereas accuracy for PTS correction was 1.0 ± 0.9°. KSS significantly improved for the clinical score from 57.4 ± 19.4 to 84.1 ± 16.6 ( Conclusion: The investigated combined PSI and PSP system shows accurate surgical accuracy for HKA and PTS correction with significant improvement of patient-reported outcomes at 1-year follow-up. Level of Evidence: Level III.
