Osseointegration of Orthopaedic Implants

Bone Ingrowth

In an effort to reduce loosening rates in orthopaedic surgeries, manufacturers have introduced various cementless technologies, including porous coatings to improve adhesion at the bone-implant interface. Retrieved porous orthopaedic implants are assessed utilizing a standardized point counting technique to determine extent of ongrowth. Implants are then dehydrated, embedded, sectioned and imaged using backscattered-SEM. Images are analyzed to determine percent of bone ingrowth and maximum depth.
