Comparing Tibial Osteotomy and Patellar Osteotomy to Pedicle Freezing in Proximal Tibial Malignant Bone Tumors: A Case Series Study.

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
BACKGROUND AND
objectivesPedicle freezing with liquid nitrogen is a biological reconstruction method used for aggressive proximal tibial tumors. This study compared outcomes between tibial and patellar osteotomy approaches.
methodsThis retrospective study included 14 patients with malignant bone tumors who underwent pedicle freezing between January 2021 and March 2024. Ten patients underwent tibial osteotomy; four underwent patellar osteotomy. Surgical differences, postoperative complications, bone union, functional recovery, and oncological outcomes were analyzed.
resultsTibial osteotomy required more plating, causing a greater increase in tibial diameter. Flap reconstruction was needed in six (60%) and two (50%) patients in the tibial osteotomy group and patellar osteotomy group, respectively. The bone nonunion rates were similar; median union times were 10.5 and 8.5 months. Wound complications occurred exclusively in the tibial osteotomy group (four patients), all regarding difficulties in wound closure and flap reconstruction. Tibial osteotomy resulted in more implant-related complications, whereas knee range of motion and Musculoskeletal Tumor Society scores were comparable. Tumor recurrence occurred in three cases (two tibial, one patellar), with two patients having preexisting metastases.
conclusionsBoth techniques were feasible with comparable union and functional outcomes. Tibial osteotomy often requires additional plating and has more wound complications. Given the preliminary nature and limited sample size of this study, further research is required.
