A knee replacement that remains painful, feels unstable or has worn or loosened can usually be assessed and explained. Sometimes the answer is a targeted fix — occasionally keyhole — rather than a complete redo; sometimes a revision is needed. Dr Yas also manages complex and unusual knees, including combined and difficult-anatomy cases.
When a replacement does not feel right
Most people do well after a knee replacement, but some are left with pain, stiffness, instability or a sense that something is wrong. That is worth taking seriously — there is often a specific, identifiable reason.
A careful assessment of your history, examination and imaging is the first step to understanding what is happening.
Options short of a full redo
Importantly, the answer to a painful replacement is not always a complete revision. Depending on the cause, there may be a more targeted solution — sometimes a keyhole procedure — that addresses the specific problem and gets you moving again.
Where a revision is genuinely needed, Dr Yas will explain why and what it involves.
Complex and unique cases
Dr Yas manages complex knees — including bicompartmental solutions, combined ligament and replacement procedures, and significant deformity. These are exactly the cases that benefit from individual planning rather than a standard approach.
Difficult anatomy and higher body weight
Difficult anatomy — including for patients with a higher body weight — is assessed individually rather than turned away. With careful planning and robotic technology, surgery can often be carried out safely.

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.
