Introduction

摘要

This fourth quarter issue of Seminars in Arthroplasty represents an outgrowth of a symposium on ceramic articulations held in conjunction with the 27th Annual Current Concepts in Joint Replacement—Winter meeting, which occurred last December in Orlando, Florida. Its continuing purpose is to describe the increasing clinical utility of ceramics as bearing surface choices for both hip and knee arthroplasty applications. Their employ manifestly extends the concept of the low-friction arthroplasty advanced by Sir John Charnley as a solution for degenerative joint disease to younger and more active patient populations.
