Key takeaways:
- Patients with and those without a nickel allergy had similar revision and reoperation rates after total knee arthroplasty.
- Researchers also found no differences in patient-reported outcomes after surgery.
SAN FRANCISCO — Results showed patients with a nickel allergy had equivalent revision rates whether they received a nickel-free implant or not during total knee arthroplasty, as well as similar outcomes as patients without a nickel allergy.
Brian P. Chalmers, MD, and colleagues matched patients with a self-reported nickel allergy to patients who did not have a self-reported nickel allergy prior to TKA for sex, BMI, American Society of Anesthesiologists classification and preoperative patient-reported outcome measures. Researchers included revision rates for nickel allergy and all causes, as well as satisfaction and patient-reported outcomes as the primary endpoints of the study.
“We did not find any difference in revision rates or reoperation rates at 2-year follow-up between patients with a self-reported nickel allergy and those without a self-reported nickel allergy,” Chalmers, of Hospital for Special Surgery, told Healio about results presented at the American Academy of Orthopaedic Surgeons Annual Meeting. “We also did not find any differences in patient-reported outcome measures at 6 weeks or 1 year after surgery.”
