Robotic Knee Replacement Surgery – Demystified!

The mention of robotic surgery conjures images of a science-fiction movie where high-tech robots perform medical feats.  Contrary to popular belief, robot-assisted total knee replacement (“TKR”) surgeries are not performed by robots in entirety. Instead, overall control of the robot is maintained by the surgeon.

Robotic Knee Replacement Surgery

The advantages of robot assisted knee replacement surgery are accuracy, consistency and the promise of a personalised natural-feeling knee!

Robotic knee systems allows the surgeon to plan and individualise the soft tissue balance, component sizing and placement as well as overall leg alignment of every patient. 

How does the Robot do this?

First, the Robotic system maps out a virtual 3D map of the knee with the help of preoperative imaging and the anatomical landmarks drawn out by the surgeon intraoperatively.

Next, a detailed personalised plan is crafted by the surgeon and executed with great accuracy by the robotic assisted arm. The accuracy of the robot allows the surgeon to preplan bone cuts and limb alignment within the submillimetre and sub-degree range.

With the use of this enabling technology, surgeons are now able to deliver highly accurate and consistent outcomes with little surprises. This translates to precise implant positioning which could potentially yield better surgical long-term outcomes such as implant longevity and patient satisfaction. In this regard, more long-term well studied clinical data may help to further optimise usage and validate surgical outcomes.

Modern day robotic knee replacement systems are designed to be efficient and value centric, utilising the latest modern prosthesis designs that have been proven to last. Enhanced recovery protocols are used in tandem with robotic knee surgery that allows patients to recover and get back on track more quickly.

It is important to reach out to a qualified surgeon for a thorough assessment and diagnosis;  and if robotic knee surgery is an option, to reach out to an experienced robotic knee surgeon.
