Book a consultation and leave with a diagnosis, your imaging explained and a written plan, whether or not that plan involves surgery.
Book ConsultationA Personalised Approach to Care
“The right treatment starts with the right diagnosis. Not everyone with hip or knee arthritis requires surgery. I aim to understand how the problem is affecting each individual patient, explain the available treatment options clearly, and make a shared decision about the most appropriate treatment.”
Despite a high-volume surgical practice, no two patients are treated the same. Surgery is never recommended simply because arthritis is present. Every decision is shared, and shaped by your symptoms, expectations, priorities and circumstances.
A Specialist Area of Practice
Complex & revision joint replacement
When a hip or knee replacement is painful, loose, unstable or infected, finding out exactly why is the essential first step. Paddy Subramanian has substantial experience in complex primary and revision arthroplasty, and regularly assesses patients with difficult problems after previous surgery.
- More than 260 hip and knee revision procedures recorded in the National Joint Registry
- Structured assessment of painful or problematic previous joint replacements
- Single and two-stage revision for infection, instability, loosening and wear
- Second opinions welcomed, from patients, GPs and other consultants
Modern Joint Replacement
Technology and pathways, used thoughtfully
Innovation is only worthwhile when it makes your outcome better. Robotics, enhanced recovery and day-case surgery are offered where the evidence supports them, never as marketing.
Robotic & Patient-Specific Technology
3D planning and robotic accuracy for precise implant positioning, with custom and patient-specific solutions where appropriate, explained honestly, benefits and limitations alike.
Robotic surgeryEnhanced Recovery
Modern anaesthesia, opiate-sparing pain relief and mobilisation within hours of surgery, a whole-pathway approach that helps every patient recover faster.
Enhanced recoveryDay-Case Joint Replacement
A day-case hip and knee replacement programme running since 2019. Carefully selected patients go home the day of surgery, and no one is discharged before they are clinically ready.
Day-case surgeryPatient Story
A complex hip replacement at 41, home the same day
Struggling to walk with a severely worn hip, this patient had a complex total hip replacement with Paddy Subramanian and went home the same day. Six weeks later, in his own words, and back on his feet. Shared with his kind permission.

About Your Surgeon
Paddy Subramanian
Consultant Orthopaedic Surgeon, BSc (Hons) MBBS MRCS MSc FRCS (Tr & Orth)
Paddy Subramanian is a consultant orthopaedic surgeon based in London whose practice is focused on hip and knee replacement, including complex revision surgery, alongside trauma care. He trained on the North London rotation before completing specialist arthroplasty fellowships, and now divides his time between NHS practice and private patients across London and Hertfordshire.
His approach is deliberately unhurried. Patients are given the time to describe the problem properly, to see and understand their own imaging, and to consider all options, including the option not to operate. Where surgery is the right answer, it is planned meticulously and delivered using modern, evidence-based technique.
Alongside primary joint replacement, Paddy Subramanian holds a specialist interest in revision surgery and regularly accepts referrals for painful or failing hip and knee replacements.
You will always see the same surgeon. The consultant who assesses you is the consultant who operates on you and the consultant who reviews your recovery.
