No clinically meaningful differences between PCL preservation and sacrifice in medial pivot total knee arthroplasty: A systematic review and meta-analysis.
Review in Journal of experimental orthopaedics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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: The decision to preserve or sacrifice the posterior cruciate ligament (PCL) during medial pivot total knee arthroplasty (TKA) remains controversial. This systematic review and meta-analysis evaluated postoperative functional outcomes and complications in patients undergoing medial pivot TKA with and without PCL preservation. Methods: Eight databases were systematically searched eight databases through July 2025 following PRISMA guidelines. Studies comparing PCL preservation (cruciate-retaining [CR]) versus sacrifice (cruciate-sacrificing [CS]) in medial pivot TKA with minimum 2-year follow-up were included. Primary outcomes were functional scores and complication rates. Due to substantial heterogeneity ( Results: Seven cohort studies (957 patients) were included. For outcomes with acceptable heterogeneity, quantitative pooling showed no statistically significant differences: Knee Society Score (KSS) (mean difference: 0.39, 95% confidence interval [CI]: -0.5, 1.27, Conclusions: Based on low to moderate certainty evidence with significant study heterogeneity, PCL management strategy does not result in clinically meaningful differences in functional outcomes or complication rates in medial pivot TKA. Level of Evidence: Level III.
