Bearing Surface
The articulating interface between prosthetic components in joint replacement surgery.
Full Definition
The bearing surface refers to the articulating interface between prosthetic components in joint replacement surgery, where relative motion occurs during normal function. Common bearing surface combinations include metal-on-polyethylene, ceramic-on-polyethylene, ceramic-on-ceramic, and metal-on-metal, each with distinct wear characteristics, longevity profiles, and potential complications. The choice of bearing surface significantly impacts implant longevity, wear debris generation, and patient-specific considerations such as age, activity level, and allergies.
Usage
Usage note: Specify material combination when discussing bearing surfaces.
