Due to certain deviations of the knee anatomy, the cartilage, the ligaments or patella, some knees are less efficient to absorb shocks and transfer forces. This means the knees will wear out faster, which may result in premature necessity for knee prosthesis. The cartilage is a tissue which does not have blood vessels. As a result, the natural regeneration of the tissue is very limited. This thesis sheds light on the most common deviations of the knee anatomy. The different models are processed and simulated to examine the influence of the knee anatomy on stress and pressure in the knee joint. Patient 1 is a male with a common knee. Patient 2 is a male with a small medial condyle of the femoral cartilage. Patient 3 is a male with a large medial condyle of the femoral cartilage. Due to ethical principles it is not possible to test the influences of the knee anatomy on a living patient. Tests can be performed on cadaver knees. The tests have to be done as soon as possible after the death of the donor. Another problem is that everyone has different knees, like fingerprints they are unique. Assembling a database containing all morphological deviations is impossible. Consequently, a cooperation with engineers is started in order to simulate and examine the knee models. The aim of the present thesis is to examine the influences of the deviations of the knee anatomy before and after a meniscectomy. Using Finite Element Analysis we examine the stress and pressure points in a human knee joint. Another aim of the present paper is to develop a procedure to optimise the model for a Finite Element Analysis. We succeeded in developing an optimisation procedure. This procedure can be used to optimise any scan for a Finite Element Analysis, which was not possible with most of the existing procedures. The developed procedure can be used in any field of research in which model optimisation of a 3D object is used. Most numerical model studies in the field of biomechanics have been focusing on stress analysis of a common knee. Medical experience, however, suggests that most knee complaints arise with divergent knees. Issues of the knee joint can be predicted and anticipated in an early stage by using Finite Element Analyses.

This open access book describes and illustrates the surgical techniques, implants, and technologies used for the purpose of personalized implantation of hip and knee components. This new and flourishing treatment philosophy offers important benefits over conventional systematic techniques, including component positioning appropriate to individual anatomy, improved surgical reproducibility and prosthetic performance, and a reduction in complications. The techniques described in the book aim to reproduce patients’ native anatomy and physiological joint laxity, thereby improving the prosthetic hip/knee kinematics and functional outcomes in the quest of the forgotten joint. They include kinematically aligned total knee/total hip arthroplasty, partial knee replacement, and hip resurfacing. The relevance of available and emerging technological tools for these personalized approaches is also explained, with coverage of, for example, robotics, computer-assisted surgery, and augmented reality. Contributions from surgeons who are considered world leaders in diverse fields of this novel surgical philosophy make this open access book will invaluable to a wide readership, from trainees at all levels to consultants practicing lower limb surgery

More than 20 years have passed since the International Symposium on Total Knee Replacement was held in London in 1974. Prosthetic design and operative technique have been greatly improved since then, and there is now an accepted standard concept of total knee arthroplasty. Thirteen years after the London symposium, another international symposium on total knee replacement was held, this time in Nagoya, Japan, in 1987. Its ambitious objective was to push forward the frontiers of continuous investigation and improve ment of total knee replacement. The fruits of the individual efforts presented at the Nagoya symposium were published in a volume of proceedings entitled Total Knee Replacement. In the years since 1987, further investigations have been conducted in various parts of the world regarding prosthetic design, fixation, long-term radiological follow-up, biomechanical evaluation, and biomaterials research. In knee ligament reconstruc tion, rapid progress has been made in the past five years in clinical practice and fundamental research by means of arthroscopic surgery and tissue transplantation, and we have come close to establishing a standard treatment. Under these circumstances, an international symposium on knee joint reconstruc tion was planned for 1994, again to be held in Nagoya, to provide ample opportunity for exchanging information and sharing clinical experience from around the world.

While several treatment options exist for knee arthritis patients, end-stage treatment is total knee arthroplasty (TKA or total knee replacement). For patients to achieve maximum benefits of this surgical correction, they need understand and manage many important details both before and in the first year after surgery. This comprehensive guide explains everything from the preoperative decision-making process to the surgery itself, how to prepare your home for post-surgery rehabilitation, and a week by week description of how to rehabilitate yourself following your TKA. The road to recovery is laid out clearly in this book in such detail that there are no surprises. It concentrates extensively on postoperative rehabilitation, which is vital to the success of a TKA, and as important as the surgery itself. This book contains 145 exercises, 190 illustrations and photos, and questions and answers at the end of each chapter. It empowers patients with the knowledge they need to take charge of their own rehabilitation program.

Each year approximately 250,000 Americans undergo total-knee-replacement surgery (also known as a total knee arthroplasty, or TKA). Every year, a million more consider it. If you are considering or have had a total knee replacement you should read this book. It will tell you everything you need to know to prepare for and recover from the surgery, and to get the most out of your new knee. The success of a total knee replacement depends on rehabilitating the knee after the operation -- in fact, the rehab is as important as the surgery itself. This book maps out the road to recovery with week-by-week exercises for a full year. The authors, a surgeon and physical therapist who have both been orthopedic patients, provide practical tips, success stories and personal insights into the recovery process. Most people, even surgeons, don't realize how dramatically arthritis can change a person's life. Author Jeff Falkel, Ph.D., was one of these people. Over the course of 20 years his knees had gotten progressively worse, and eventually the pain reached the point where it was present in every aspect of his life. He could not stand or walk without crippling pain.

This is the true story of the misadventures of Joey McQuaig, a middle-aged man, who a tears the cartilage in his knee. Osteoarthritis soon develops in both knees and spreads to both hips. The doctor's orders are for total knee and hip replacements. Joey is going to be a "4 by 4." Amazingly, he returns to physical activity as he did...twenty years ago earlier, even though his body is older, his hips and knees are titanium. The results are comical as our survivor slips, slides, stumbles and falls-down stairs, off roofs, from ladders and out of vehicles. He learns quickly that titanium doesn't make you Superman...or does it? Joey, a former athlete, decides to resume jogging and begin a search for ways to renew vigor in his life. Along the way, he learns to manufacture natural pain killers and discontinues his meds. Throughout the book you learn of his simple, down-home philosophy about living life with gusto even with titanium joints. With a chance for a renewed life, Joey's endurance of bilateral knee and hip replacements led him to discover "to whom God has given much, much is required to give back to others." Rather than following old and worn paths, he cuts new trails and encourages other to do the same. This survivor learned early on "not to quit" and he doesn't. This inspirational story moves from humorous to profound as readers are challenged to determine what is restricting their growth-physically, mentally, emotionally and spiritually as they are asked, "Do you have a wish-bone or a back-bone?" We have a final warning from Joey, "Follow doctor's orders...and your heart as well."
