The Efficacy of 3D Printing Model in the Intraarticular Osteotomy in the Treatment of Malunion of Tibial Plateau Fracture.
Article in Orthopaedic surgery, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
objectivesThree-dimensional (3D) printing technology has shown potential advantages in accurate and efficient tibial plateau fracture (TPF) treatment. This technology can provide structural morphology to repair fracture fragments. Here, we summarize our experience with the use of 3D printing technology during intraarticular osteotomy in the treatment of the malunion of TPF.
methodsThe patients who were treated with malunion of TPF in our hospital between January 2015 and December 2018 were retrospectively analyzed. These patients were divided into two groups: the conventional group without 3D-printed model application and the 3D printing group with 3D-printed model application. All patients received the intraarticular osteotomy during operation, and we compared the operation time (min), fracture healing time (months), postoperative knee Rasmussen scores (0-30 points), knee mobility range (0-140°) (the independent t-test), fracture reduction evaluation (Biggi's method) (the chi-square test: Fisher's exact test), and postoperative complications of each group.
resultsTwenty-six patients aged 18-65 years who underwent TPF revision operation were included in this study, including 18 patients in the conventional group, and eight patients in the 3D printing group. The follow-up time was 24-48 months, and the operation time was 185 min in the conventional group and 180 min in the 3D printing group. All patients received a bone union at the last follow-up. The healing time was 4.2 months in the conventional group and 3.75 months in the 3D printing group (p > 0.05). The respective postoperative Rasmussen scores were 24.6 and 26.2, and postoperative knee mobility was 103.5° and 118.5° in the conventional group and 3D printing group, respectively. Both the Rasmussen scores and degrees of mobility were significantly improved after surgery (p < 0.05), and the postoperative knee mobility was significantly better in the 3D printing group versus the conventional group (p < 0.05). Four patients still had a 2-mm collapse on the articular surface, and two patients still had slight valgus (<5°) in the conventional group. Only one case in the 3D printing group suffered from an articular surface collapse. Superficial wound infections occurred in two patients in the conventional group.
conclusionThe results show that 3D printing technology is an effective preoperative preparation in the treatment of TPF malunion. This technology can facilitate accurate preoperative planning to select the optimal surgical approach, plan the implant placement, visualize the screw trajectory, and anticipate possible intraoperative difficulties.
