To my wife Sibylle with gratitude for 40years ofunderstanding collaboration Preface Orthopaedic surgery today is undergoing a phase of turbulent development. Once the essential aim of treatment consisted in restitution of anatomy by surgery in order to restore function. Various forms of alloplasty have recently become fashionable for the treatment of joint diseases. The main reason for this vogue is that restoration of normal anatomy improves function and alleviates pain only in certain special instances. Alternatively, the implantation of artificial joints of different types has been presented as the method of choice because the immediate results are often spectacular to the patient and the operative technique is relatively easily learned. Nevertheless, more and more voices are being heard, drawing attention to numerous bad results that appear after shorter or longer periods. In the first instance, these failures consist of unexpected and undesirable reactions between the foreign material and the tissues of the locomotor system. Bony resorption due to locally exaggerated stressing plays an essential part. A promising alternative to the use of prostheses and the many problems arising therefrom is to make use of the natural capacity for functional adaptation possessed by the tissue of the skeleton. The principle of this method of treatment is, by exact planning of the necessary alteration of stress, to restore the biomechanical equilibrium between the amount and type of mechanical stressing, on the one hand, and the capacity of the tissue reaction to support it on the oth
