The first chapter “”Design Principles”” is a topic that has always intrigued me since my days working on the Total Condylar Prosthesis. The next several chapters focus on the surgical treatment of basic arthritic deformities which is the bedrock of adult reconstruction of the knee. Chapters 7 and 8 deal with the management of femoral and tibil bone defects with the use of bone grafts and briefly allude to the newer trabecular metals. The next two chapters describe the technique and debate the merits of comented and comentless fixation. Chapter 11 through 17 are concerned with specific knee designs and their indications including a chapter discussing the utility of computer navigation. The book closes with five chapters on challenging knee conditions including infection, extra-articular deformity, and periprosthetic fracture. TABLE OF CONTENTS: 1. Design Principles, 2.
