Do knee replacements cause metal poisoning?

Knee replacements typically do not cause metal poisoning in most patients. The materials used in prosthetic implants, such as titanium or cobalt-chromium alloys, are biocompatible and designed to minimize adverse reactions. However, in rare cases, some individuals may experience metal sensitivity or elevated metal ions in their bloodstream, which can lead to localized reactions or other complications. Regular follow-up with a healthcare provider can help monitor any potential issues.
