IMPLANT DESIGN & CORROSION
Arthroplasty design is a critical component of long-term outcomes and implants survival in joint replacement surgery. Taper corrosion, trunnion failure, and adverse local tissue reaction (ALTR) are rare but devastating problems that limit overall implant survival that are related to corrosion. There are a series of studies in progress being completed to improve the diagnosis and treatment of corrosion in arthroplasty surgery to increase overall implant survival.
