Over the past two decades, knee replacement technologies have seen significant advances in both patient outcomes and cost-effectiveness have improved. Technologies like Total Knee Replacement have made a lot of advancements but technological advancements are still going on.

In this article, we will discuss the new knee replacement technology 2022 and other advancements. The article will cover the latest developments in knee replacement surgery and new robotic knee replacement surgeries.


Latest Developments in Knee Replacement Surgery

Minimally-Invasive Surgery (MIS)

It includes one of the latest developments in knee replacement surgery. Experts have agreed that MIS represents a revolution in inpatient care. MIS has revolutionized orthopaedic surgery and patient benefits are undeniable.

Many general surgeon readers may feel skeptical about the approach to minimally invasive surgery. which entails the use of micro-incisions and using powerful miniature tools that greatly simplify joint resurfacing.

Significantly, Surgeons who utilize techniques can find themselves responsible for reduced blood loss. It is no longer needing a sponge or drain, a shorter hospital stay, less pain, quicker recovery, less scarring, a lower rate of infection, faster return to work, lower readmission rate, a better quality of life, and improved aesthetics.

Total Knee Arthroplasty (TKA)

It is a highly effective surgery to treat severe osteoarthritis. The latest developments in TKA lead to effective outcomes in returning to daily activities, good survival rates, and entire functional improvements. The latest developments are focus on improving patient satisfaction after TKA- Total Knee Arthroscopy.

New technologies are being included in patient-specific instruments, smart tools, computer-assisted surgery, and navigation. To individualize the surgery and improve the accuracy of the procedure. The technological developments include surgical planning in 3D and increase alignment reliability. to provide improved implant positioning.

New Robotic Knee Replacement Surgery

The new robotic replacement involves a similar procedure such as the traditional knee replacement surgery. The difference is that it is done by a technologically advanced robotic arm that performs the surgery with high precision. The new robotic knee replacement surgery provides high precision, better results, and shorter recovery times.

This surgery provides a great balance in the soft tissues around the patient’s knee and provides a better alignment of the joint. 

Types of Robotic Knee Replacement Surgeries

1. Mako Robotic Assisted Knee Surgery

It may assist surgeons to visualize their pins while the pins are being placed. An intra-operative fluoro system is integrated into the system. It enables direct pin placement on a virtual 3D-CT model. It helps to make Mako robotic-assisted surgery a possibility. This instrument requires six joints, two pulleys, and four electric motors. whereas, the standard Mako arm has only five degrees of freedom.

A prototype kinematic system designed to interface with the standard Mako arm. It includes two driven pulleys with servo motors, two active belts. Lead screw with position sensors allows for the exact positioning of pins. By measuring their position relative to kinematic reference points of the Mako’s arm. It can accurate pins without being dependent on exact knowledge of the original surgical incision or template.

2. The Navio Cori Surgical Systems

Navio Cori is a computer-guided robot designed for orthopaedic surgery. It is built with open-source hardware and software components to provide surgical benefits. In human body, it targets specific soft tissue anatomy like medial femoral condyle. This robot allows precise robotic drilling of bony surface preparation with millimeter accuracy. Ensuring more effective procedures and better clinical outcomes. these benefits were not available in any other medical device.

A Mako system has a slight difference from Navio. The Mako robot utilizes specific scans for the knee before surgery to get proper measurements. The patients who have opted for traditional knee replacement can also opt for robotic knee replacement. This surgery is ideal even for high complex joint diseases. This involves patients who have:

  • Complex degeneration

  • Femur deformities after injury

  • Hardware from previous surgery


Knee replacement technologies are witnessing rapid advancements in upcoming years. All surgical operations will operate through robotic technologies that will provide better results. and a shorter recovery time. Robotic-assisted knee replacement technologies will become more advanced. People suffering from knee pain will get better treatment.

We hope that article has introduced you to the new knee replacement technologies and their contribution. to knee replacement. Surgeries like MIS and TKA are going to see much more advancements in 2022. With the inclusion of smart tools If you are about to get knee replacement surgery. One can consider New Knee Replacement Technology 2022 for a better and precise surgery. We wish you good luck in your future ventures and hope for the best.
