A decade later, a group of new metals and metal alloys became available for the construction of artificial knees, hips, and other joints. These included stainless steel, cohalt, and titanium products. Since that time, these materials have been the most popular materials from which joint replacements, as well as supporting structures for the immobilization of fractures, have been made. 

Excess bone/scar tissue formation - this may occur around the artificial knee joint, resulting in restricted joint movement. Removal of the excess bone/scar tissue may necessitate further surgery to restore movement. 

Tantalum alloys are used in artificial knees as well as hips and other joints. IMAGE COPYRIGHT 2009, VADIM KOZLOVSKY. USED UNDER LICENSE FROM SHUTTERSTOCK.COM. 

A prosthetic device is an artificial Limb or body part such as an artificial knee or hip. 

As a final example of a MR fluid controlled adaptronic system, the smart prosthesis knee developed by Biedermann Motech GmbH [178-181] is presented. This system shown in Fig. 6.91 is a complete artificial knee that automatically adapts and responds in real-time to changing conditions to provide the most natural gait possible for above-knee amputees. The heart of this system is a small magnetorheological fluid damper that is used to semi-actively control the motion of the knee based on inputs from a group...

Joint replacements, such as artificial knees, elbows, and hips, require major surgery but have become relatively commonplace because suitable materials have become available for not only the bone replacement but also the contact surfaces. In knee replacement, for example, the goal is usually to replace worn-out cartilage surfaces (which may have resulted from arthritis or injury). It is possible to replace shattered bones that cannot heal back to their original state as well.
