Joint replacement surgery is a common orthopaedic procedure used for the treatment of diseased or damaged joints. The majority of these replacement systems incorporate a stemmed portion which is inserted into the bone canal, either with or without bone cement, to achieve fixation to the host bone. Although this procedure has proven effective, relative displacement at the bone-cement and/or cement-stem interfaces (i.e., implant loosening) is a common complication, leading to pain and the need for revision surgery.
