Giant cell tumor (GCT) of the bone, although benign, demonstrates local aggressiveness, a potential for recurrence, and, in rare instances, malignant transformation. Functional preservation is crucial in cases involving the articular surface, often utilizing the Sandwich Technique. We propose an enhanced reconstruction method using the inner table of the iliac crest in a reverse fashion, offering a more anatomically contoured proximal tibial plateau and reducing donor site morbidity compared to tricortical iliac crest grafting. This technique ensures that the marrow and cancellous bone facing the articular cartilage provide essential nourishment for articular cartilage, preventing early joint arthritis.
骨巨细胞瘤（GCT）虽为良性，但具有局部侵袭性、复发可能性，且在罕见情况下会发生恶性转化。在涉及关节面的病例中，功能保留至关重要，常采用三明治技术。我们提出一种改进的重建方法，以相反方式使用髂嵴内板，与三皮质髂嵴植骨相比，能提供更符合解剖形态的胫骨近端平台轮廓，并降低供区并发症。该技术可确保面向关节软骨的骨髓和松质骨为关节软骨提供必要营养，预防早期关节关节炎。
