Taper Corrosion and Adverse Local Tissue Reactions in Patients with a Modular Knee Prosthesis

摘要

Background:Corrosion has been documented in modular knee implants, but it has not been related to negative patient outcomes. We performed an observational retrieval investigation of 13 Stryker Triathlon TS modular knee implants, 3 of which were revised because of osteolysis and adverse local tissue reactions secondary to fretting corrosion at the modular junctions.
