TOTAL KNEE REPLACEMENT The types of implants that are available in these two designs are further available in two types: The fixed bearing implants namely all Poly and Metal Back. And, mobile bearing implants where the insert is mobile which moves through the knee movements allowing more movement and less wear and tear. Some of these implants also come with Oxynium coating which helps in reducing wear and tear, thus increasing the life of implants. Biological TKR It is a TKR, performed using techniques which are more biological, less invasive and traumatic, leading to early recovery to day to day activities. 1) Using Sub Vastus Approach – A less invasive muscle reflecting approach instead of the one where muscle is cut, leading to early recovery and easier postoperative physio rehabilitation. 2) Using CAS (Computer Assisted Surgery) technology – Leading to less bone loss and more precise bone cuts and near normal deformity correction. 3) Using CAS (Computer Assisted Surgery) technology – Leading to less bone loss and more precise bone cuts and near normal deformity correction. 4) Using PS Implants – Using Posterior Stabilizing (PS) implants, where the PCL (Posterior Cruciate Ligament) is preserved, a less invasive soft tissue protecting approach.Using Uncemented Implants – This achieves a more biological fixation of implants, abolishes the need for cement, and thus avoids cement related complications.
