Arthroscopic fixation versus open reduction and internal fixation for displaced tibial side posterior cruciate ligament avulsion fractures: A systematic review and meta-analysis.
Review in Journal of orthopaedics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper, 1 of them a synthesis that pooled it.
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: The reported incidence of the posterior cruciate ligament (PCL) injury ranges from 3 to 23 % of all knee injuries. Several injury patterns of the PCL have been described, including intra-substance, femoral detachment, and tibial avulsion, of which the last two are more common. Displaced PCL avulsion injury from the tibial side requires surgical fixation; however, there is no consensus in the literature regarding the optimal surgical approach for the fixation of these injuries. Purpose: To perform a systematic review and meta-analysis of the outcomes and complications of arthroscopic and open fixation of displaced tibial side PCL avulsion fractures. Methods: We performed a primary electronic search across PubMed, Embase, Scopus, and Cochrane Library databases and looked for comparative studies that evaluated and compared the outcomes of arthroscopic versus open reduction and fixation of displaced tibial side PCL avulsion fractures. Statistical analyses were executed with the software RevMan-5.4.1. Results: This meta-analysis included two RCTs, one prospective and seven retrospective comparative studies. Evaluation across all ten studies suggested no statistically significant difference for arthroscopic versus open fixation in terms of postoperative International Knee Documentation Committee (IKDC) score (MD 4.43 [-0.73, 9.42; p = 0.09]), Lysholm score (MD 2.69 [-1.07,6.45; p = 0.16], knee range of motion (ROM) (MD -1.08 [-2.80,0.63; p = 0.21]), complications (OR1.75 [0.86, 3.54; P = 0.12]), Tegner activity (MD 0.14 [-0.46,0.74; p = 0.64]), posterior tibial translation (PTT) (MD -0.60 [-1.51,0.31; p = 0.20, posterior drawer test (PDT), operating time (MD 12.03 [-0.47, 24.53; p = 0.06]), and length of hospital stay. The fracture union rate was 98.77 % in the arthroscopic group and 100 % in the open fixation group, with comparable union time. There is a significantly lesser amount of blood loss in the arthroscopic group compared to the open group. Conclusion: Current evidence shows comparable outcomes and complications for tibial side PCL avulsion fracture fixation through arthroscopic or open methods.
