Event Description

This complaint is from a literature source.The following literature cite has been reviewed: sheridan ga, neufeld me, sidhu a, kurmis ap, kelly m, o'byrne jm, howard lc, masri ba, garbuz ds.The diagnostic utility of serum metal ion markers for high-grade aseptic lymphocyte-dominated vasculitis-associated lesions (alvals) in revision hip and knee arthroplasty: an international multicenter study.J arthroplasty.2024 jan;39(1):206-210.Doi: 10.1016/j.Arth.2023.06.024.Epub 2023 jun 16.Pmid: 37331438.Objective and methods: aseptic lymphocyte-dominated vasculitis-associated lesions (alvals) are typically described in the context of metal-on-metal (mom) hip bearings.This study explores the diagnostic utility of preoperative serum cobalt and chromium ion levels in determining the histological grade of alval in revision hip and knee arthroplasty.This was a multicenter retrospective review of 26 hips and 13 knees assessing the correlation between preoperative ion levels (mg/l (ppb)) and the histological grade of alval from intraoperative specimens.All metal ion levels were recorded within 3 months of the revision surgery.The cobalt: chromium (co:cr) ratio was also calculated based on these levels.All revision surgery was performed between january 1, 2011 and december 31, 2022.All revision procedures were performed at varying time intervals from the index procedure in hospitals located in canada, australia, and dublin, ireland.The article does not specify which revisions occurred in each country of event.Results: the depuy products revised in the study included 9 asr hip resurfacing constructs (head and cup), 1 duraloc/corail tha construct (cup, head, liner, and stem), 2 lcs and 1 attune tkas (femoral, insert, tibial tray).There is no indication that the patellas were resurfaced and the manufacturer of the cement utilized in the tkas was not provided.The results for the competitor constructs will be excluded from this complaint.The indications for all tha revisions were symptomatic armd and for the tkas was aseptic loosening.Histologic samples taken from the revision procedures identified synovitis, metallosis, metal debris (hips only), and pseudotumor.Additionally, serum cobalt and chromium levels were confirmed to be elevated above 7 ppb.
