The application of mini T-plate and high-strength suture wires in the surgical treatment of posterior cruciate ligament avulsion fractures: a retrospective case series.
Article in BMC surgery, 2026. 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 1 paper.
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
backgroundPosterior cruciate ligament (PCL) avulsion fractures at the tibial insertion can cause posterior knee instability and accelerate osteoarthritis. Meyers-McKeever type II/III fractures require surgery. Traditional open approaches are traumatic, while arthroscopic techniques are limited by equipment, learning curves, and fixation efficacy.
objectiveTo evaluate the short-term clinical outcomes and feasibility of a combined vertical medial posterior incision approach using a small T-plate and high-strength suture fixation for isolated PCL avulsion fractures.
methodsWe retrospectively reviewed 21 patients with isolated Meyers-McKeever type II/III PCL tibial avulsion fractures treated with posteromedial longitudinal mini-incision fixation using a mini T-plate combined with high-strength suture. Operative parameters, fracture healing, knee ROM, Tegner-Lysholm score, IKDC score, posterior drawer test, and complications were assessed.
resultsThe mean surgery duration was 81.5 ± 20.9 min, with an average intraoperative blood loss of 33 ± 11 ml. All fractures achieved anatomical reduction, with an average healing time of 10.9 ± 1.6 weeks. At the final follow-up (mean 10.6 ± 5.2 months), knee ROM improved significantly from 76.5°±12.1° preoperatively to 132.2°±4.2° (P < 0.05). Both Tegner-Lysholm scores (from 45.5 ± 9.3 to 95.5 ± 2.8) and IKDC scores (from 35.9 ± 8.9 to 96.8 ± 1.5) showed statistically significant improvements (P < 0.05). The posterior drawer test was negative in all patients, and no infection, implant failure, or gastrocnemius weakness was observed.
conclusionPosteromedial longitudinal mini-incision fixation with a mini T-plate combined with high-strength suture achieved satisfactory clinical outcomes for PCL tibial avulsion fractures. The proposed 5T concept summarizes the main practical advantages of this technique. In this descriptive case series (Level IV evidence), the technique achieved satisfactory short-term clinical outcomes for PCL tibial avulsion fractures, particularly in patients with small or comminuted fragments. Further prospective comparative studies are needed to validate its long-term clinical value.
