MEGA MAYO STUDY FOR METAPHYSEAL SLEEVES IN REVISION TKA (Orthopedics This Week)
Mayo Clinic researchers have completed a 280 patient/393 metaphyseal sleeve study—the largest to date—of revision total knee arthroplasty (TKA). Their work, “Survivorship of Metaphyseal Sleeves in Revision Total Knee Arthroplasty,” (http://www.arthroplastyjournal.org/article/S0883-5403(16)30874-9/abstract) was published in May 2017 edition of The Journal of Arthroplasty.
Mark Pagnano, M.D., chair of the Department of Orthopedic Surgery at Mayo Clinic and a co-author on the study, commented to OTW, “This is the largest study to date to report the results of metaphyseal sleeves used in revision total knee replacement. The vast majority of patients in this series had moderate bone loss problems and in only a few cases were the indications for use stretched to include patients with very severe Type 3 bone defects.”
He and his co-authors wrote, “Metaphyseal fixation has promising early results in providing component stability and fixation in revision total knee arthroplasty (TKA). However, there are limited studies on midterm results of metaphyseal sleeves…”
“Two hundred eighty patients with 393 metaphyseal ...
