What is New in Knee Replacement?

If you are considering knee replacement surgery, there are new developments under study which can help enhance their quality of life. These include:

• Computer navigation and robot assisted surgery allows increased accuracy in the placement of the knee replacement and correction of the shape of the leg. Use of navigation-guided surgery that involves use of navigation-guided instruments with smaller incisions and less tissue damage. Only suitably trained surgeons are able to offer this procedure.
• Use of cementless parts that allow new bone to grow into a porous prosthesis and hold the parts in place, creating a biologic fixation
• Use of bioactive joint surfaces such as hydroxyapatite – this encourages robust fixation of the implant to the bone
• Development of systems with improved kinematics
• Better fixation
