Prevalence of metal hypersensitivity in total knee replacement.

ABSTRACT:

Background

Cutaneous and local reactions to metals used in orthopaedic implants have been well documented. The prevalence of metal sensitivity in general population is 10%-15%. Nickel, Cobalt and Chromium are the most common allergen. The association between cutaneous reactions and implants has been less understood. Hence, this study was taken up with the aim to assess the prevalence of metal hypersensitivity in Total Knee Replacement (TKR) patients and find the most prevalent allergen.

Materials & methods

Longitudinal study conducted during January-December 2017. We enrolled 233 subjects who were at least three months postoperative. Radiological assessment was done. CREDISOL® kit was used for patch test. Results were recorded using ICDRG grading at 48 hours and five days.
