Release of Chromium from Orthopaedic Hip & Knee Replacements

- Many orthopaedic implants are composed of alloys containing chromium.
- There is an increasing number of Cobalt Chromium hip and knew replacements being inserted into young patients with osteoarthritis.
- Such implants will release chromium ions.
- These patients will be exposed to the released chromium for over 50 years in some cases.
- The subsequent chromium ion metabolism and redistribution in fluid and tissue compartments is complex and most likely to be damaging.
- In addition, the potential biological effects of chromium are also controversial, including DNA and chromosomal damage, reduction in CD8 lymphocyte levels and possible hypersensitivity reactions (ALVAL).
