A knee replacement resurfaces the worn joint with implant components. Dr Yas’ focus is on planning each one to your individual anatomy — restoring your own joint lines for a more natural-feeling knee — and using robotic technology to carry that plan out precisely. Non-surgical options are always discussed first; a replacement is recommended only when it is genuinely the right step.
Who it is for
A knee replacement tends to suit people whose osteoarthritis significantly affects their quality of life — their walking, sleep and the activities they value — when non-surgical measures are no longer giving enough relief.
Non-surgical options we try first
Before considering surgery, Dr Yas will discuss the non-surgical measures that help many people — strengthening and physiotherapy, activity and weight management, and injections where appropriate. Surgery is recommended only when these are no longer enough.
What a knee replacement involves
The worn surfaces of the joint are resurfaced with implant components — typically on the end of the thigh bone and the top of the shin bone, with a smooth bearing between them. The aim is a stable, comfortable knee that moves naturally.
How Dr Yas personalises it
Rather than aligning every knee to a single standard, Dr Yas uses personalised (kinematic) alignment where it suits — planning the replacement to restore your own natural joint lines, which can give a more natural-feeling knee.
Robotic planning and execution are the tools that carry this plan out precisely. The technology serves the judgement; it does not replace it. Standard implants are designed for average anatomy — and you are not average.
Anaesthetic, surgery and your stay
Your anaesthetic and length of stay are planned around you and discussed beforehand. Most people are up and moving with the team soon after surgery, then continue a guided rehabilitation programme.
Risks and how they are reduced
Every operation carries risks, and a knee replacement is no exception. Dr Yas will explain these clearly and how careful planning and technique are used to reduce them — so you can make an informed decision.
Your recovery roadmap
A typical guide — individual recovery varies, and Dr Yas will tailor yours.

Explore the four pillars
Want surgery designed for your anatomy, not the average?
Joint-preserving partial replacement where suitable, personalised total replacement with kinematic alignment and robotic precision, and direct anterior hip surgery — matched to your joint, not a standard mould.
Had a replacement that still doesn’t feel right?
When a replacement hasn’t worked out there is often a specific reason — and a specific solution. An independent review: examination, imaging reviewed, and a written summary of your options.
Been told you’re too young, too heavy, or to just wait?
Dr Yas reviews each patient case by case and recommends the operation that fits the joint — not the other way around. Higher-BMI patients considered on their individual merits, not declined on weight alone.
Been told nothing more can be done?
Specialist revision hip & knee surgery, partial-to-total conversion with modern bone-preserving technique, and complex reconstruction after trauma — including limb-preserving surgery — considered case-by-case.
