Patient-Specific Cutting Guides for Alignment-Correcting Osteotomy About the Knee: A Study of Accuracy, Cost, and Surgical and Fluoroscopic Safety.

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
Background: The utility and safety of patient-specific cutting guides (PSCGs) in osteotomies about the knee is uncertain. Purpose: To compare the cost, accuracy of radiographic correction, and safety of PSCG versus standard cutting guide (SCG) corrective osteotomies about the knee. Study Design: Cohort study; Level of evidence, 3. Methods: Patients undergoing high tibial osteotomy (HTO) or distal femoral osteotomy (DFO) were retrospectively reviewed from 2017 to 2022. Those who underwent 3-dimensional PSCG osteotomy were propensity matched to patients undergoing traditional osteotomies. Procedure time and fluoroscopic details were extracted from operative notes. Hip-knee-ankle (HKA) angle, posterior tibial slope (PTS), and mechanical axis deviation were measured on pre- and postoperative radiographs. Intraclass correlation coefficients were calculated to determine the reliability between the intended and resultant correction of HKA. Time-driven activity-based costing (TDABC) analysis was performed to compare procedure costs. Results: A total of 42 patients were included, with 11 HTOs and 10 DFOs in each group. Between the SCG and PSCG groups, respectively, final HKA (2.7° vs 1.9°; Conclusion: Both traditionally guided osteotomies and PSCG-guided osteotomies accurately corrected lower extremity malalignment. Utilization of PSCG resulted in similar procedure times and cost, as well as less fluoroscopy and lower tourniquet time, compared with conventional osteotomy. PSCG trended toward a decreased rate of postoperative complications.
