Pigmented villonodular synovitis (PVNS) is caused by a proliferation of the synovial membrane and can be a rare cause of pain and locking of the knee. In its localized form, it can be removed arthroscopically. We describe in detail a step-by-step arthroscopic technique applied to treat a 27-year-old patient who had been suffering from pain and episodes of locking for a year and whose left knee MRI revealed an intra-articular mass. The formation was completely enucleated arthroscopically and histological analyses confirmed the diagnosis of localized PVNS. There were no complications, and the patient was symptom-free at the six-month follow-up with no clinical or radiological evidence of recurrence.
色素沉着绒毛结节性滑膜炎（PVNS）是由滑膜增生引起的，可能是膝关节疼痛和交锁的罕见原因。在其局限性形式中，可以通过关节镜切除。我们详细描述了一种逐步的关节镜技术，用于治疗一名27岁的患者，该患者已经遭受疼痛和交锁发作一年，其左膝MRI显示关节内有肿块。通过关节镜将该肿物完全摘除，组织学分析证实为局限性PVNS。没有并发症，患者在六个月的随访中无症状，没有临床或影像学复发证据。
