Giant cell tumor of the tendon sheath (GCTTS) originates from the synovial cells of the tendon sheath. It is one of the most common benign soft-tissue tumors of the foot and ankle affecting the joints, bursae, and tendon sheaths and can behave in a locally aggressive manner. Complete surgical resection with long-term follow-up is the preferred treatment. Because GCTTS is a benign condition, the equilibrium between the quality of the surgical margins and functional preservation should be considered. If more aggressive resection is applied, the outcome may negatively affect quality of life, whereas incomplete resection may lead to recurrence. The purpose of this technical note is to describe the details of endoscopic en bloc resection of GCTTS of the anterior ankle. This endoscopic approach can provide a magnified view of the operative site, allowing accurate surgical assessment to ensure complete resection of the lesion without damage to the adjacent normal structures.
腱鞘巨细胞瘤（GCTTS）起源于腱鞘的滑膜细胞。它是足踝部最常见的良性软组织肿瘤之一，可累及关节、滑囊和腱鞘，且具有局部侵袭性。完整手术切除并长期随访是首选治疗方法。由于GCTTS是一种良性疾病，应考虑手术切缘质量与功能保留之间的平衡。如果采用更激进的切除方式，结果可能会对生活质量产生负面影响，而不完全切除可能导致复发。本技术说明的目的是描述踝关节前部GCTTS的内镜整块切除细节。这种内镜方法可以提供手术部位的放大视野，便于进行准确的手术评估，以确保在不损伤相邻正常结构的情况下完整切除病变。
