This orthopedic trauma learning case reviews the surgical management principles for a posterolateral depression fracture of the tibial plateau. The lesson emphasizes anatomical exposure of the lateral knee, use of limb positioning and varus stress to improve visualization, careful preservation and retraction of the meniscus, direct assessment of the articular depression, and reduction with subchondral support. The case also discusses decision-making around alternative approaches, including why a posterolateral approach or fibular osteotomy may be avoided in selected scenarios. Learners follow the sequence from incision planning and soft-tissue handling to elevation of the depressed fragment, bone void filling, fluoroscopic assessment, and screw placement using a subchondral support or 'jail' configuration. The content is intended for procedural education and anatomical reasoning, not as a substitute for supervised surgical training or clinical judgment.
