Summary

This trial is comparing two types of knee implants to see if there is a difference in patient reported outcome scores for those with nickel sensitivity.

Who is the study for?
This trial is for adults with knee arthritis who are getting a total knee arthroplasty (TKA) and have self-reported nickel allergies. They must be able to speak English and not have any medical conditions that would prevent them from having elective TKA.
What is being tested?
The study aims to compare the outcomes of patients with nickel sensitivity undergoing knee replacement surgery using either standard cobalt chromium components or nickel-free implants.
What are the potential side effects?
While specific side effects aren't listed, typical risks of knee replacement surgery may include pain, swelling, infection risk at the surgical site, blood clots, and possible reaction to implant materials.
