What Is VELYS Robotic-Assisted Knee Replacement?

Robotic-assisted knee replacement is one of the most significant advances in joint replacement surgery in recent years. It's also widely misunderstood — so here's what it actually involves, in plain terms.

It's a Tool, Not a Robot Surgeon

Despite the name, robotic-assisted surgery doesn't mean a robot operates on you. The surgery is performed by Mr George; the robotic system, VELYS, assists with planning and precision, functioning more like an advanced guidance tool than an autonomous device.

Personalised Surgical Planning

Before surgery, detailed data about your specific knee anatomy — its shape, alignment, and the extent of wear — is used to build a surgical plan tailored to your knee specifically, rather than relying on generic implant positioning based on average anatomy.

This planning stage means decisions about implant size, position, and alignment are made with far more individual detail than was traditionally possible.

Greater Precision During Surgery

During the procedure, the robotic system provides real-time feedback that helps Mr George execute the surgical plan with a high degree of accuracy, supporting more consistent implant alignment and positioning than manual instrumentation alone typically allows.

This precision is particularly valuable in knees with complex deformity or significant wear, where accurate alignment has a meaningful impact on how the joint functions afterward.

What It Means for Patients

The aim of robotic assistance is a more personalised fit for your specific knee, which can support better function, more natural movement, and — for many patients — a smoother recovery compared with less precisely positioned implants.

It's important to understand that the technology supports the surgeon's skill and judgement; it doesn't replace it. The quality of the outcome still depends heavily on surgical experience and decision-making.

Is It Right for Everyone?

Not every patient is automatically a candidate for robotic-assisted surgery, and it isn't inherently 'better' for every case — for some knees, conventional techniques remain entirely appropriate and effective.

Mr George will assess your specific case and discuss whether robotic-assisted knee replacement is suitable for you as part of your consultation, alongside a clear explanation of what to expect from the procedure and recovery.
