Robotics Unicompartmental Knee Resurfacing

What is Normal Knee Anatomy and Arthritis?

In a normal knee, the bone ends do not touch each other because they are covered by a thin cushion called cartilage, which appears as a space between the bones on X-rays. Arthritis is the wear-and-tear of the cartilage in one part of the knee (called a ‘compartment’), while the other two compartments remain healthy.

What is Unicompartmental Knee Resurfacing?

In Unicompartmental Knee Resurfacing (or partial knee replacement), only the worn cartilage in one compartment is resurfaced with metal and polyethylene, while preserving the rest of the normal knee. By resurfacing only one compartment at the right time, the normal knee joint is preserved, and a total knee replacement can be avoided or delayed for over 15 years.

Role of Robotics in Unicompartmental Knee Resurfacing

With advancements in medical technology, robotics plays a crucial role in this procedure. Robotic-assisted surgery allows for greater precision during the resurfacing process, ensuring that only the damaged cartilage is treated while protecting the surrounding healthy tissue.

This precision leads to better alignment, improved outcomes, and a quicker recovery, further extending the lifespan of the partial knee replacement.
