VELYS Robotic Knee Replacement in Reading

    VELYS is a surgeon-controlled robotic system that guides a total knee replacement while it is being performed. It does not carry out the operation: it gives Mr Nahas real-time measurements to position the implant and balance the soft tissues accurately. It is CT-free and imageless, so no additional scan is needed beforehand.

    Mr Sam Nahas offers VELYS robotic-assisted total knee replacement (TKR) at Circle Reading Hospital, serving Reading and Berkshire.

    Circle Health Group is rolling out VELYS systems nationally, including at Reading, to support robotic-assisted knee replacement pathways.

    What is VELYS and how does it work?

    Imageless, CT-free workflow: intra-operative mapping (no routine pre-op CT).

    Bed-mounted platform: compact set-up that integrates into theatre workflow.

    Real-time surgical insights: assists with component positioning and balancing tailored to your anatomy.

    VELYS is designed for total knee replacement and is used alongside modern implant systems. Your exact plan is personalised following consultation and imaging.

    A balanced, evidence-led view

    Potential benefits of robotic assistance include helping surgeons perform knee replacement with precision and personalisation; some providers note possible improvements in comfort and recovery, though results vary between patients.

    In the UK, the National Institute of Clinical Excellence (NICE) lists VELYS among the robot-assisted options that may be used within an evidence-generation programme (with appropriate approvals) to build further real-world data. This reflects a cautious, data-driven approach.

    Not everyone needs robotic assistance; many achieve excellent outcomes with conventional TKR. Mr Nahas will explain where VELYS fits for your knee and goals.

    Who is suitable?

    Symptomatic knee arthritis affecting quality of life despite non-operative care.

    Candidates for total knee replacement where precision alignment and soft-tissue balancing are important.

    Your pathway in Reading

    Consultation: history, examination, review of imaging.

    Imaging: X-rays arranged promptly; advanced scans only if indicated.

    Pre-assessment: safety checks; complete 5-day antibacterial washes before surgery.

    Surgery: VELYS robotic-assisted TKR at Circle Reading Hospital with an experienced orthopaedic team.

    Enhanced recovery: early mobilisation and a clear physio-led plan.

    Recovery and rehabilitation

    Most patients walk the same day or next morning after TKR and follow a structured rehab plan with milestones and clear safety-netting.

    Risks and safety

    All knee replacements carry risks such as infection, stiffness, clots, nerve/vessel injury, and implant-related issues over time. Robotic assistance does not remove these risks; it is an enabling tool used within a comprehensive, safety-focused pathway (pre-assessment, infection prevention, and physiotherapy).

    VELYS vs conventional TKR — making the choice

    Goal: both aim to relieve pain and restore function.

    Technique: VELYS adds CT-free, imageless guidance and real-time data to support accuracy and balance.

    Selection: your anatomy, arthritis pattern, and preferences guide whether robotic assistance is recommended.

    If your arthritis is confined to one compartment, partial knee replacement (UKR) may be considered.

    FAQs

    Is VELYS suitable for everyone?

    No. Suitability depends on clinical findings and imaging; Mr Nahas will discuss benefits and alternatives.

    Does VELYS guarantee faster recovery?

    Recovery depends on your health, pain control, surgical factors, and physiotherapy engagement. Robotic guidance supports precision; it doesn't replace rehab.

    Is VELYS available at Circle Reading Hospital?

    Yes, VELYS is immediately available at Circle Reading.
