What’s new in knee replacement?
For a patient considering knee replacement surgery, there are new developments under study which can help enhance their quality of life. These include:
- First, using cementless parts that allow new bone to grow into a porous prosthesis and hold the parts in place, creating a biologic fixation
- The use of mobile-bearing knee replacement. This is where a polyethylene insert creates a dual-surface articulation by articulating with the femoral as well as tibial components. This will enhance the life of the implant by reducing wear.
- Development of systems with improved kinematics
- Better fixation
- A use of bioactive joint surfaces such as hydroxyapatite, a major component and an essential ingredient of normal bone and teeth.
- Use of navigation- guided surgery that involves the use of navigation –guided instruments with smaller incisions and less tissue damage. Only suitable trained surgeons with various measures offer this procedure.
