The relationship between psoriasis and complications after primary TKA is not well defined. Current studies are limited to small, single-center studies evaluating fewer than 150 patients with psoriasis, with some studies reporting an increased risk of surgical site infection (SSI) and another reporting no associated risk. There is a need to reevaluate the risk of psoriasis and postoperative complications, including SSI, to better risk-stratify and guide practice in this patient population.

牛皮癣是初次全膝关节置换术后手术部位感染的危险因素。

银屑病与初次全膝关节置换术后并发症之间的关系尚不明确。目前的研究仅限于评估少于 150 名银屑病患者的小型单中心研究，一些研究报告手术部位感染 (SSI) 的风险增加，而另一项研究报告没有相关风险。有必要重新评估银屑病和术后并发症（包括 SSI）的风险，以更好地对这一患者群体进行风险分层并指导实践。
