Although individual reconstructive techniques are well documented, current literature lacks a widely accepted consensus regarding their simultaneous execution. In this context, three-dimensional preoperative planning and structured sequencing logic are critical for preventing tunnel convergence and preserving the biological viability of the grafts.\n                    <jats:italic>Methodological Framework Description:<\/jats:italic>\n                    A structured reconstructive strategy is proposed to optimize surgical exposure and avoid spatial conflicts and graft interference. The workflow begins with a systematic arthroscopic mapping followed by a wide arthrotomy, adhering to a \u201csurface restoration-to-stabilization\u201d logic, consisting of: (1) customized femoral osteochondral shell allograft transplantation; (2) tibial osteochondral transplantation using a cylindrical plug technique; (3) medial meniscal allograft transplantation with dovetail bone fixation; and (4) anatomic ACL reconstruction using a soft tissue tendon allograft. This specific sequencing allows stabilizing elements to be adapted to the already restored articular anatomy, minimizing tunnel convergence and protecting soft-tissue grafts from aggressive osseous surgical maneuvers.\n                    <jats:italic>Clinical Relevance:<\/jats:italic>\n                    This technical-conceptual work provides a structured roadmap to support surgical decision-making in highly complex reconstructive cases. By systematizing operative sequencing and the management of technical interferences, the proposed workflow enables a reproducible biological reconstruction strategy aimed at restoring articular homeostasis in young and active patients within a single surgical procedure.\n
