Diffuse-type tenosynovial giant-cell tumor (D-TGCT), formerly known as pigmented villonodular synovitis, is a rare, locally aggressive, invasive soft tissue tumor that primarily occurs in the knee. Surgical excision is the main treatment option, but there is a high recurrence rate. Arthroscopic surgical techniques are emphasized because they are less traumatic and offer faster postoperative recovery, but detailed reports on arthroscopic techniques and outcomes of D-TGCT in large cohorts are still lacking.

膝关节弥漫型腱鞘巨细胞瘤患者接受多通道关节镜滑膜切除术后的复发率、并发症和功能结果如何？

弥漫型腱鞘巨细胞瘤（D-TGCT），以前称为色素沉着绒毛结节性滑膜炎，是一种罕见的局部侵袭性、侵袭性软组织肿瘤，主要发生在膝关节。手术切除是主要治疗方法，但复发率较高。关节镜手术技术受到重视，因为它们创伤较小且术后恢复更快，但仍缺乏关于关节镜技术和大队列 D-TGCT 结果的详细报告。
