Can local infiltration analgesia supplemented with tranexamic acid reduce blood loss during total knee arthroplasty?
Article in BMC musculoskeletal disorders, 2024. 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
purposeThe aim of this study was to investigate the efficacy of TXA supplemented with local infiltration analgesia (LIA) for reducing blood loss in patients undergoing total knee replacement. MATERIALS: A retrospective study of 530 individuals with a mean age of 71.44 years was performed after posterior stabilized total knee arthroplasty. Patients were divided into three groups according to the method of bleeding control: I - patients without an additional bleeding protocol (control group); II - patients receiving IV TXA (TXA group); and III - patients receiving the exact TXA protocol plus intraoperative local infiltration analgesia (TXA + LIA group). Blood loss was measured according to the maximal decrease in Hb compared to the preoperative Hb level.
resultsThe mean hospitalization duration was 7.02 (SD 1.34) days in the control group, 6.08 (SD 1.06) days in the TXA group, and 5.56 (SD 0.79) in the TXA + LIA group. The most significant decrease in haemoglobin was found in the control group, which was an average of 30.08%. The average decrease in haemoglobin was 25.17% (p < 0.001) in the TXA group and 23.67% (p < 0.001) in the TXA + LIA group. A decrease in the rate of allogeneic blood transfusions was observed: 24.4% in the control group, 9.9% in the TXA group, and 8% in the TXA + LIA group (p < 0.01).
conclusionsCompared to the separate administration of tranexamic acid, the combination of perioperative administration with local infiltration analgesia significantly reduced blood loss in patients after total knee replacement.
