NCT ID: NCT02208271 Suspended - Clinical trials for Arthritis, Failure of Total Hip

A Validated Necrosis Assay to Determine the Need for Revision Surgery in Metal-on-metal Total Hip Arthroplasty

Start date: August 4, 2014
Phase:
Study type: Observational

The purpose of the study is to develop a biomarker assay to be used as a diagnostic tool for adverse local tissue reaction, or tissue necrosis, in a metal on metal total hip replacement. A convenience sample of a total of 100 hip patients will be enrolled: 50 metal-on-metal revision hips, 25 metal-on-poly revision hips, and 25 pre-operative total hips (no implant, control group) will be enrolled. Preoperative blood serum samples and intraoperative synovial fluid will be obtained from all hips and used for biomarker testing. Additionally, intraoperative assessment of tissue necrosis will be assessed.
