In 1981, Gensch and Schmitt described a case of reticular telangiectatic erythema (RTE) associated with a cardiac pacemaker device1. RTE is clinically characterized by an asymptomatic or mildly pruritic cutaneous eruption that presents as a blanching redness in a netlike or blotchy pattern on or near the site of an implant. The occurrence of RTE in association with nonorthopaedic devices such as cardiac pacemakers has previously been reported, mostly in the dermatology literature2-16. In these reports, the appearance of RTE often occurred after the implantation of the devices, with a time frame ranging from fifteen days to four years. We report two cases of RTE that were associated with orthopaedic implants. RTE of the knee after joint replacement surgery is a benign skin reaction that can be mistaken for cellulitis, infection associated with the prosthesis, tinea corporis (ringworm), or allergic contact dermatitis to the metallic or nonmetallic components of the medical prosthesis. The patients were informed that data concerning their cases would be submitted for publication, and they both provided consent.
