Allergic dermatitis after total knee arthroplasty using the prineo wound-closure device: A report of three cases

Case: Three patients who underwent uncomplicated total knee arthroplasty with use of the Prineo (Ethicon) woundclosure system had development of allergic contact dermatitis. All patients were started on Keflex (cephalexin), and two were started on topical corticosteroid. In all patients, the reaction resolved within weeks. Conclusion: To our knowledge, the present report describes the first case series of patients in whom allergic contact dermatitis developed in association with the use of the Prineo wound-closure system during orthopaedic procedures. The presentation can range from blistering to erythematous papules and vesicles to crusted plaques that resolve with Keflex and topical corticosteroid cream.
