Cannulated screw tension band versus Kirschner wire tension band for patellar fractures: A systematic review and meta-analysis.
Synthesis in Joint diseases and related surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectivesThis meta-analysis aimed to systematically compare the clinical outcomes of cannulated screw tension band (CSTB) and Kirschner wire tension band (KWTB) fixation for patellar fractures. MATERIALS AND
methodsComprehensive searches were conducted in the Cochrane Library, Web of Science, PubMed, Embase, and SpringerLink databases for studies published through July 2025. Search terms included "cannulated screw," "Kirschner wire," "tension band," and "patellar fracture." Mean differences (MDs) and odds ratios (ORs) were utilized as pooled effect measures, with 95% confidence intervals (CIs).
resultsEleven studies involving 1,358 patients with patellar fractures met the inclusion criteria. Meta-analysis revealed no statistically significant differences between the groups in terms of operative time (MD = 4.00; 95% CI -1.82~9.82; p = 0.18), fracture healing time (MD = 0.08; 95% CI -0.07~0.22; p = 0.28), or postoperative Visual Analog Scale scores (MD = 0.21; 95% CI -0.74~1.15; p = 0.67). However, CSTB fixation demonstrated significantly superior postoperative knee range of motion (ROM) (MD = -7.16; 95% CI -9.34~-4.98; p < 0.00001), higher Lysholm scores (MD = -4.80; 95% CI -6.62~-2.99; p < 0.00001), and significantly lower rates of reoperation (OR = 5.14; 95% CI 2.66~9.93; p < 0.00001) and overall complications (OR = 14.19; 95% CI 4.85~41.56; p < 0.00001) compared to KWTB.
conclusionFor patellar fracture fixation, CSTB offers significant advantages over KWTB in terms of postoperative knee ROM, functional outcomes, reoperation rates, and overall complication rates.
