Minimally Invasive Approach to Multiligament Knee Reconstruction: Arthroscopic PCL and PLC With Percutaneous LCL Reconstruction.
Article in Video journal of sports medicine. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: Multiligament knee injuries involving the posterior cruciate ligament (PCL), posterolateral corner (PLC), and lateral collateral ligament (LCL) are rare but complex pathologies. Historically managed with open surgery, these injuries are increasingly being addressed using minimally invasive techniques, which provide anatomical reconstruction and less surgical morbidity. Indications: We report the case of a 24-year-old male farmer who sustained a high-energy multiligament knee injury after a motorcycle accident. Six months after the accident, he presented with persistent daily instability affecting his work and recreational activities. Clinical and radiological evaluation confirmed chronic injuries to the PCL, PLC, and LCL. Technique Description: A 1-stage, all-arthroscopic and percutaneous reconstruction was performed. The PCL was reconstructed using a pedicled semitendinosus autograft with tibial tunnel placement via a trans-septal portal for direct visualization. The PLC was addressed arthroscopically by placing a knotless anchor for femoral fixation of the reconstructed popliteus tendon, using an extensor hallucis longus allograft. The LCL was reconstructed using a gracilis autograft via a percutaneous technique, minimizing soft-tissue dissection and avoiding tunnel convergence. This minimally invasive strategy enabled anatomical graft placement with reduced risk of neurovascular injury and greater potential for accelerated recovery. Results: Postoperatively, the patient wore a hinged PCL dynamic brace for 3 months with no weightbearing for the first 6 weeks. Physical therapy was initiated immediately after surgery with a focus on a controlled range of motion and progressive strengthening. The aim was to allow him to safely return to manual labor and sports activities 6 to 9 months after the surgery. Discussion/Conclusion: This case highlights the feasibility and effectiveness of a 1-stage, all-arthroscopic, percutaneous reconstruction of chronic PCL, PLC, and LCL injuries. This technique provides reliable anatomical restoration with minimal surgical morbidity and promising early clinical outcomes, particularly in physically demanding patients.
