The reader is enthusiastically encouraged to tackle this second edition text in two ways. The first is simply to scan chapters with their introductions, summaries and conclusion points. Second, is to delve into those sections of seeming greater interest depending upon one s s- cialty and role. The expansion and quality of this material speak to the success of the first edition by these editors and many similar authors. In addition, the continued and enlarged interest in computer assisted Orthopedic surgery indicates the relevance and enduring importance of this advance in our field of...

Worldwide experience with the Lcs mobile bearing total knee prosthesis has been unpar alleled both in terms of enduring popularity and outstanding long-term clinical results. Buechel and Pappas's design was based on the principles of; restoring anatomical joint function to as near normal as possible, minimising contact stresses to avoid wear and darn age to the bearing surfaces. and finally the idea that constraint should refiect the need for mobility, to avoid shear stresses and loosening of the implant. In 1977, the LCS(r) knee was implanted by Dr. Frederick Buechel. This was the first...

Orthopaedic surgery is urr c ently just a few moments past the sunrise of computer implementation for the per- formance of surgery itself. OUT pe s cialty has always seemed to have a nearly unique. over arching characteristic -it deals almost exclusively with alteration, typically rebuilding or reconstituting. structure. What we do has more of a structural impact than a physiologic one, even when compared to the structural alterations introduced by vascular and cardiac surgery_ This structural reconstitution contrasts strongly with the largely excisional haracteri c stic of most other ur...
