Total Knee Replacement
Evolution of Total Knee Replacement
Total knee replacement surgeries have been performed for over a century and the technology and techniques has continued to advance throughout the history of the procedure. Currently the most common material used for components are various metal alloys to include titanium, cobalt-chrome, well as high grade plastics or polyethyelene that serve as the gliding surface, commonly known as “poly.”
Total Knee systems consist of three party, the femoral component that attaches to the end of the femur, the tibia components that affixes to the of tibia, and the poly that rests between the two metal compoentns and acts as the new cartilage or bearing surface. There is often a plastic poly button that is shaped onto the knee cap to assist with gliding of the patella.
Many various companies produce total knee components used in total knee replacement and all of the currently used implants have been extensively studied and approved to be safe for use by the US Food and Drug Administration.
Regardless of the implant chosen by the surgeon, due to the continued and drastic improvements in technology and material properties throughout the history of total knee replacement procedures, current implants are the best that we have ever had. Today, knee replacements implants demonstrate the best in improved wear rates, longer longevity of the implants, higher success rates, more anatomic designs, and decreased need for revision surgery due to wear or loosening.
The Smith and Nephew Journey IITM Total Knee Arthroplasty system is an innovative option for use in total knee replacement. The components are designed to improve range of motion and improve knee function following surgery. This is accomplished through the component design which allow for more anatomic knee motion following replacement. The system comes with multiple options for surgeons with regard to component design and ability to retain ligaments within the knee that may otherwise need to be sacrificed.
This allows the surgeon to have a greater amount of control over the implants that they desire to use. The Journey II system is also compatible with multiple other products to include custom 3D printed cutting guides, and surgical navigation technologies which allow the surgeon to have even more options at their disposal. Although the choice of implant should always be determined by the surgeon, allowing them to choose the product they are most comfortable with, the Smith and Nephew Journey IITM Total Knee Arthroplasty system is an incredible technology.
