Tibial condylar valgus osteotomy for posttraumatic varus deformity secondary to malunited tibial plateau fractures: a retrospective cohort study.

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
backgroundThis study evaluated the efficacy of tibial condylar valgus osteotomy (TCVO) for correcting varus deformity following malunited tibial plateau fractures.
methodsA retrospective cohort analysis was performed on patients undergoing TCVO (January 2019 - June 2023). Radiographic parameters comprised Mechanical Axis position (%MA), Medial Proximal Tibial Angle (MPTA), Femorotibial Angle (FTA), Joint Line Convergence Angle (JLCA), Medial Tibial Plateau Depression (MTPD), and Posterior Proximal Tibial Angle (PPTA). Functional outcomes were evaluated using Knee Society Score (KSS), Lysholm Knee Score (LKS), and Visual Analog Scale (VAS).
resultsA total of 29 patients with posttraumatic knee varus deformity secondary to malunited tibial plateau fractures were included in this study (mean postoperative follow-up 21.3 ± 7.6 months) and demonstrated osseous union at 15.3 ± 1.6 weeks. The %MA improved from 1.4 ± 14.8% preoperatively to 60.0 ± 8.1%, while the FTA decreased from 186.7 ± 2.9 to 172.1 ± 2.1°. MPTA improved from 82.6 ± 1.3° before surgery to 87.1 ± 1.6° afterwards. JLCA decreased from 5.5 ± 1.5° preoperatively to 1.1 ± 0.9° postoperatively. The MTPD decreased from 6.4 ± 1.8° to 1.1 ± 1.0°. Postoperative assessments indicated significant improvements in knee function with Knee Society Scale (KSS) improved from 48.4 ± 14.1 to 88.6 ± 4.7 and Lysholm Knee Score (LKS) improved from 51.6 ± 9.8 to 90.1 ± 3.6.
conclusionTCVO effectively restores limb alignment and functional capacity in patients with malunion-induced varus deformity, providing a viable solution for this complex posttraumatic condition.
