title: Dermatitis associated with chromium following total knee arthroplasty.
abstract: All metal implants release metal ions because of corrosion. Although 20% to 25% of patients develop metal sensitivity after total joint arthroplasty, which is 10% higher than that in the general population, only very few highly susceptible patients exhibit symptoms. Even patients with known metal allergy often do not react to their metal prosthesis. Systemic allergic contact dermatitis is particularly uncommon with total knee arthroplasty because there is no metal-on-metal contact between the femoral and tibial components. We present a case report of 62-year-old man with dermatitis most likely caused by chromium after total knee arthroplasty and review the relevant literature. Although this complication is very rare, it sometimes can be painful enough for the patient to undergo revision surgery.
