Preoperative MRI abnormalities are not associated with poor outcomes or altered surgical planning in unicompartmental knee arthroplasty: a systematic review and meta-analysis.
Synthesis in European journal of orthopaedic surgery & traumatology : orthopedie traumatologie, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 3 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
purposeTo evaluate the association between preoperative MRI imaging and clinical outcomes following Unicompartmental knee arthroplasty (UKA).
methodsWe searched PubMed, Scopus, Web of Science, and Embase for studies related to preoperative MRI abnormalities and clinical outcomes in patients undergoing UKA. The quality assessment was done by the National Institutes of Health's (NIH) Study Quality Assessment Tools. A random-effects model with Hedges'g (standardized mean difference, SMD) and 95% confidence intervals (CIs) was used to assess the impact of meniscal injury and bone marrow lesions (BMLs) on clinical outcomes.
results18 studies (2751 patients) were included. The meta-analysis found that preoperative meniscal injury (Hedges' g = - 0.060, p = 0.544) and bone marrow lesions (Hedges' g = - 0.197, p = 0.386) did not significantly impact clinical outcomes following UKA. Other MRI abnormalities, such as those affecting the anterior cruciate ligament (ACL) integrity, did not impact the functional outcomes. However, findings regarding cartilage defects were inconsistent.
conclusionPreoperative MRI features such as meniscus injury, BML, and ACL integrity did not result in equivalent clinical outcomes following UKA and may not necessitate altering the surgical plan. Surgeons should integrate MRI findings with clinical assessment and patient-specific factors rather than relying solely on these imaging abnormalities to guide decision-making.
