Titanium alloy, in its Ti-318 (Ti-A16-V4) format, is a widely used material for orthopaedic implants. However, it has frequently been reported as causing black staining of the periprosthetic tissues as a result of debris from metallic wear. This process of metallosis has been implicated in implant failure. We report three cases in which titanium alloy prostheses for primary bone tumours at the knee have caused the formation of fluid-filled cysts containing metallic debris. The cysts result in radiological appearances which may mimic soft tissue tumour recurrence and also contribute to post-operative failure of the extensor mechanism of the knee.
钛合金，以其Ti - 318（Ti - A16 - V4）的形式，是一种广泛用于骨科植入物的材料。然而，经常有报道称，由于金属磨损产生的碎屑，它会导致假体周围组织出现黑色染色。这种金属沉着病的过程与植入物失败有关。我们报告了三例病例，其中用于膝关节原发性骨肿瘤的钛合金假体导致了含有金属碎屑的充满液体的囊肿形成。这些囊肿导致的放射学表现可能会模仿软组织肿瘤复发，并且也会导致膝关节伸肌机制的术后失败。
