What is the conventional TKR implant made up of?

The metal components are made up of highly polished Cobalt Chromium alloy which are cemented  to the bone & separating the two is a special Polyethylene spacer which gives a perfect new articulation for a smooth functioning knee.

What are the new materials used to increase the longevity of the implant?

The newer generation of implants tough made up of cobalt chromium are coated with special materials like ceramic or gold leading to reduced wear & tear making the implant last longer Another important invention is using a highly cross-linked polyethylene spacer  which some times has added Vitamin E to make it harder to wear off These new materials now claim the longevity of the implant to increased from the conventional 15 years to 25 – 30 years, thus giving longer pain free life without needing revision surgeries.

What is navigated Knee replacement?

Navigated TKR is performed using a special device which acts as a sensor to guide the operating surgeon regarding the correct placement of the implants instead of eyeballing. It requires a CT scan of the knee after assessing the scan the parameters are fed in the software & the knee is operated upon based on the calculations.

What is Robotic Knee replacement?

Robotic Knee replacement is an advancement over the Navigation technique where after the mapping of the knee the bone cuts are taken by a robotic arm to increase precision of the surgery.
