VELYS™ Robotic-Assisted Solution for Knee Replacement at Euxton Hall Hospital in Chorley

VELYS™ Robotic-Assisted Solution for Knee Replacement at Euxton Hall Hospital

The VELYS™ Robotic-Assisted Solution is an advanced technology used by orthopaedic surgeons to support highly accurate and personalised knee replacement surgery. It is an image-free system, meaning you do not need pre-operative CT or MRI scans. Instead, it uses real-time data, optical trackers and an infrared camera to build a 3D model of your knee during surgery, helping your surgeon make precise decisions throughout the procedure.

VELYS™ works seamlessly with the J&J Medical ATTUNE™ Knee Replacement System, an innovative implant designed to improve stability, reduce pain and create a more natural-feeling knee. The J&J Medical ATTUNE™ Knee Replacement System has been shown to help patients feel more confident in their knee performance, experience less pain at the front of the knee and return to everyday activities sooner. The J&J Medical ATTUNE™ Knee Replacement System is manufactured by DePuy Synthes which is the orthopaedic and medical device division of Johnson & Johnson. [1, 2]

At Ramsay Health Care, our experienced orthopaedic consultants use robotic-assisted technology, including the VELYS™ system, to support a smoother recovery and help patients return to daily life with greater confidence.

Knee replacement: Key trends and outcomes

Knee replacement surgery is advancing quickly, with robotic-assisted techniques becoming a major part of modern care. Current global evidence shows:

  • Over 3.6 million knee replacements were performed worldwide in 2023.

  • Robotic-assisted surgery has grown sixfold in six years and now makes up 13.4% of all knee replacements.

  • Many patients experience a significant reduction in pain and improved day-to-day mobility after surgery.

  • Knee replacements are highly durable, with 93% lasting at least 15 years and 82% still functioning at 25 years (this may be influenced by factors such as patient age, mobility, anatomy and degree of arthritis).

  • Recovery continues to improve and many patients walk unaided within six weeks and return to low-impact activities such as swimming or cycling by seven weeks.

These trends show a clear shift toward more precise, personalised surgery and consistently improving long-term outcomes for patients.

How VELYS™ Robotic-Assisted Solution for knee replacement works

The VELYS™ system uses an infrared camera and optical trackers to gather real-time information about your knee during your surgery. This helps your surgeon plan and perform your knee replacement with a high degree of accuracy.

The VELYS™ robotic system 

  • does not operate on its own, your surgeon remains in full control (and makes decisions based on your knee and the information gathered).

  • provides detailed data about your knee’s anatomy to support precise bone preparation.

  • helps your surgeon position your ATTUNE™ Knee System implant accurately, based on your individual movement and alignment.

This personalised approach supports a more natural-feeling knee and improved recovery. 

Benefits of VELYS™ robotic-assisted knee replacement with ATTUNE™ Knee System

The VELYS™ Robotic-Assisted Solution supports a more accurate and personalised knee replacement by using real-time data to guide implant positioning. When combined with the ATTUNE™ Knee System, this approach is designed to improve stability, reduce pain and help the knee feel more natural during movement.

Patient’s experience

  • Improved knee stability and reduced discomfort as a result of more precise alignment and implant placement

  • Greater confidence in knee performance

  • Many patients report an earlier recovery and return to normal daily activities

What the evidence shows

Two global studies 1,2  comparing the ATTUNE™ Knee System with another leading system found:

  • Greater confidence in knee performance

  • Less pain at the front of the knee

  • Improved ability to perform daily activities

  • Better overall quality of life

Patients often walk unaided within six weeks and return to low-impact exercise, such as swimming or cycling, by around seven weeks.

Patient satisfaction with ATTUNE™ Knee

Real-world National Joint Registry data shows:

  • 91% of patients feel better after knee replacement with the ATTUNE™ Knee

  • 88% are satisfied with their surgical outcome

These results are significantly higher than the overall class of knee implants.

Success with VELYS™

Success with VELYS™ robotic-assisted knee replacement is measured by accuracy, stability and patient-reported outcomes. When paired with the ATTUNE™ Knee System, patients consistently report:

  • Less pain

  • Greater confidence in their knee

  • Improved quality of life

  • Faster return to activity

Together, VELYS™ precision and ATTUNE™ implant design support reliable long-term results and high patient satisfaction.

FAQs

What is a VELYS™ knee replacement?

A VELYS™ knee replacement is a total knee replacement performed using the VELYS™ Robotic-Assisted Solution with an ATTUNE™ Knee System implant. The technology helps your surgeon plan and carry out your knee replacement with enhanced accuracy, based on your individual anatomy and movement.

What is the difference between VELYS™ and other Robotic Assisted Knee Replacements?

All are robotic-assisted systems used in knee replacement surgery, but they work differently:

  • VELYS™ is an image-free system that uses real-time data, optical trackers, and an infrared camera.

  • Others typically uses pre-operative CT scans to create a 3D model of the knee. 

VELYS™ allows your surgeon to make decisions based on live information during surgery, without the need for CT imaging.

Who is not a good candidate for robotic knee replacement?

Robotic-assisted knee replacement may not be suitable for everyone, including patients with:

  • Severe bone loss

  • Certain deformities

  • Active infection

  • Medical conditions that make surgery unsafe

Your orthopaedic surgeon will assess your suitability during consultation.

Why choose VELYS™ robotic-assisted knee replacement?

Patients may choose VELYS™ because it offers:

  • Personalised implant positioning

  • High surgical accuracy

  • A natural-feeling knee when paired with the ATTUNE™ system

  • Faster recovery and improved early function

  • Strong patient satisfaction outcomes

Which robotic-assisted knee replacement is best?

There is no single “best” system for every patient. The right choice depends on your anatomy, your surgeon’s expertise, and your treatment goals. VELYS™ is a strong option for patients seeking a CT-free, real-time, highly accurate robotic-assisted procedure.
