title: [Nickel allergy and painful unicondylar knee arthroplasty].
abstract: A 56-year-old woman with unicondylar knee arthroplasty (Oxford III, Biomet) complained of persistent, burning pain in her knee. The arthroplasty failure was caused by a nickel allergy. The diagnosis was confirmed by positive patch testing, lymphocyte transformation test and histological analysis of the neosynovia around the implant. The unicondylar knee arthroplasty was explanted and replaced by a titanium-coated knee prosthesis (INNEX CR, Zimmer).
