Metallosis following prosthetic hip and knee replacement is a well-known complication. However, unicompartmental knee arthroplasty (UKA) metallosis is rare. In this paper, we report a case of septic metallosis after unicompartmental knee replacement and we review the literature for the available treatment options.
A 83-year-old female patient presented with left periprosthetic knee infection on the top of unicompartmental knee prosthesis three months after septic endocarditis that was treated with anti-biotherapy. Surgical exploration showed severe infected metallosis due to chronic polyethylene wear reaction; hence, management consisted of total synovectomy and debridement of all metallic debris and two stage revision.
Metallosis is a well-known complication after prosthetic hip and knee replacements. However, in UKA, it remains a rare complication where only few cases were reported in the literature.
人工髋关节和膝关节置换术后金属沉着病是一种众所周知的并发症。然而，单髁膝关节置换术（UKA）后的金属沉着病很少见。在本文中，我们报告了一例单髁膝关节置换术后感染性金属沉着病病例，并回顾了文献中可用的治疗选择。
一名83岁女性患者，在感染性心内膜炎接受抗生物治疗三个月后，出现单髁膝关节假体上方左膝关节周围感染。手术探查显示，由于慢性聚乙烯磨损反应导致严重的感染性金属沉着病；因此，治疗包括全滑膜切除术、清除所有金属碎屑以及两阶段翻修术。
金属沉着病是人工髋关节和膝关节置换术后众所周知的并发症。然而，在单髁膝关节置换术中，它仍然是一种罕见的并发症，文献中仅报道了少数病例。
