"Clinical presentation "
"Metallosis is the deposition of metallic debris into periprosthetic soft tissues. Metallic microparticles are generated from repetitive abrasion of metallic hardware, such as from metal-on-metal arthroplasty, modular reconstruction components (such as at the prosthetic femoral head–neck interface, called trunnionosis), or fractured fixation plates 1. The debris can involve the joint capsule, cavity, and/or extra-articular tissues."
