Herpes zoster is a clinical manifestation of reactivation of varicella-zoster virus (VZV) that lies dormant in the dorsal root ganglia after a past primary infection. It can be associated with severe pain, a crop of vesicles in typical dermatomal distribution but the neuralgic pain persists long, making the patient uncomfortable and often disturbing patient's sleep. There are cases reported after trauma or post surgeries that are mainly related to organ transplant or malignancy. In the literature, there is a solitary report of VZV infection along the sciatic nerve post ipsilateral hip and contralateral knee joint replacement. Here, we report a VZV infection in post knee replacement setting along the L2-3 dermatomal distribution.
带状疱疹是水痘-带状疱疹病毒（VZV）再激活的临床表现，该病毒在既往初次感染后潜伏于背根神经节。它可能伴有严重疼痛，出现典型皮节分布的水疱群，但神经痛持续时间长，使患者不适，常常干扰患者睡眠。有创伤或手术后发生带状疱疹的病例报道，主要与器官移植或恶性肿瘤有关。在文献中，有一份关于同侧髋关节和对侧膝关节置换术后沿坐骨神经发生VZV感染的单独报告。在此，我们报告一例膝关节置换术后沿L2-3皮节分布发生的VZV感染。
