ICJR Interviews: Survivorship Improving for Rotating Hinge Implants
Historically, hinged implants for total knee arthroplasty did not allow for rotation at the junction, which resulted in high failure rates.
Today, outcomes have vastly improved with the addition of rotation, as demonstrated by 94% implant survivorship free of aseptic loosening in more than 400 patients treated with a contemporary rotating hinge implant at Mayo Clinic.
Matthew P. Abdel, MD, said he and his colleagues found that utilizing metaphyseal fixation devices with the rotating hinge implant also helped to reduce aseptic loosening in their study population.
Although aseptic loosening has become less of an issue, deep periprosthetic joint infections continue to be a problem. Dr. Abdel said that isn’t really surprising, given that these are challenging patients for whom use of the rotating hinge implant is a salvage procedure.
