Biomechanical comparison of patellar cementing techniques in total knee arthroplasty: a biomechanical study.
Article in BMC musculoskeletal disorders, 2025. 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
objectivesThe aim of this study was to biomechanically compare three different cementing techniques for patellar component fixation in total knee arthroplasty. MATERIALS AND
methodsSynthetic patellar bone model (Selbones© Research Laboratory, Kayseri, Turkey) was implanted with an all-polyethylene universal dome patellar component (Trauson
resultsThe mean peak stress pressure of a total of 30 test specimens was 1305.86 (± 24.72) N (Newton) and these values were determined as 1013.00 (± 24.72), 1334.60 (± 37.17) and 1570.00 (± 26.56) N for group 1, group 2 and group 3, respectively (p < 0.001). A statistically significant difference was found in the multiple comparisons of all groups with each other and fixation of group 3 was found to be better than group 1 and 2 (p < 0.001).
conclusionThe modified cementing technique demonstrated superior biomechanical fixation strength compared to conventional methods in this in vitro study. This low-cost and easily applicable technique may help reduce patellar component-related complications and warrants further evaluation in clinical settings.
