Total knee arthroplasty in patients with psoriasis.

Patients with progressive psoriasis have an increased infection rate when having total joint arthroplasty. Therefore, maximum precautions should be taken in the perioperative period as well as with long-term follow-up care to prevent joint sepsis in these patients. In particular, skin care should be meticulous. Special attention should be given to use of a topical corticosteroid or other dermatologic treatment when total joint arthroplasty is considered.
