Commentary on “Treatment of posterolateral tibial plateau fractures: a narrative review and therapeutic strategy”

Dear Editor, We read with great interest the comprehensive narrative review by Liu et al., titled “Treatment of posterolateral tibial plateau fractures: a narrative review and therapeutic strategy”[1]. The authors provide a timely and clinically relevant synthesis of contemporary concepts in the management of these challenging fractures, from injury mechanism to surgical fixation. Our commentary was prepared in accordance with the TITAN 2025 guidelines for transparency in artificial intelligence reporting[2].We commend the structured overview of classification systems, surgical approaches, and implant options, which collectively offer valuable guidance to orthopedic surgeons. Two interrelated aspects may further enhance the clinical interpretation and practical application of the proposed strategy. First, while the “bicondylar four-quadrant” classification is well illustrated and logically applied to approach selection, its operationalization in preoperative planning could be strengthened by incorporating quantitative imaging parameters. For instance, the extent of posterolateral articular involvement (e.g., < 1/3 vs > 1/3 of lateral articular area) and the integrity of the posterolateral cortex are critical determinants in choosing between a supra-fibular head approach and a combined posteromedial approach. Standardizing these radiographic thresholds – possibly through CT-based mapping or 3D reconstruction – could reduce subjectivity and improve reproducibility across centers[3]. Second, the review highlights the horizontal belt plate as an effective implant for posterolateral fractures, particularly when applied via the supra-fibular head approach. However, the biomechanical rationale and comparative performance of this implant relative to conventional rafting plates or posterolateral buttress plates deserve deeper contextualization. Although several novel plate designs are mentioned, their clinical adoption remains limited. A more explicit discussion of implant selection principles – such as fracture morphology (split vs depression), bone quality, and soft-tissue safety – would help surgeons tailor fixation to individual fracture patterns. Furthermore, the role of arthroscopic-assisted internal fixation (ARIF) is acknowledged as promising, but its integration into the proposed therapeutic algorithm remains somewhat tentative. Clarifying the indications for ARIF – for instance, in fractures with minimal displacement or associated meniscal/ligamentous injuries – could better define its niche within the treatment pathway[4]. We also note the emphasis on avoiding neurovascular injury, particularly with posterior approaches. The detailed anatomical measurements provided are instructive, yet practical intraoperative strategies to minimize risk – such as the use of intraoperative imaging, nerve monitoring, or staged approaches in complex cases – could be further elaborated to enhance procedural safety. In summary, we commend the authors for a thorough and clinically useful review. Refining classification-based decision rules with imaging metrics, elaborating implant selection rationale, and clarifying the role of ARIF may further optimize the management of posterolateral tibial plateau fractures and guide future comparative studies. Sincerely,
