Dear Colleague and Participant in Bioceramics and Alternative Bearings In Joint Arthroplasty: 10*" International BIOLOX® Symposium We are once again very proud that we are able to present to you the proceedings of the Symposiunn as part of your registration materials. This group accomplishment has been made possible by the superb cooperation received from the speakers in sending us their manuscripts on a timely basis as well as by the supporting staff at both CeramTec and at the Publishing House in executing all of the details needed. We specially extend our most heartfelt thanks to the Scientific Committee for their assistance in evaluating and selecting the submissions as well as developing the Symposium program. We are more convinced than ever that the proceedings of this Symposium are a continuation of CeramTec's tradition of providing all members of the orthopedic surgical community with a valuable addition to your reference libraries. We hope that this book will present you with the latest and most up to date source of scientific and clinical information regarding the use of ceramics and other alternative bearings in joint replacement surgery.
