A knee for sport.
A knee for life.
I treat sports injuries, kneecap problems and knee arthritis for patients of all ages. When surgery is needed, I aim to repair or replace only the damaged part of the knee.

What's troubling your knee?
Start with what you're experiencing. Each page explains the problem, your options with and without surgery, and what recovery looks like.
I've injured my knee
Twisting injuries, a knee that gives way, locking or swelling after sport.
My kneecap hurts or slips
Pain at the front of the knee, or a kneecap that dislocates or feels unstable.
I have knee arthritis
Pain, stiffness and wear that is limiting walking, sleep or daily life.
"Surgery is not always the answer. When it is, my philosophy is to treat only the damaged part of your knee and keep as much of your own joint as possible."

A specialist knee surgeon for York and North Yorkshire
I have been a Consultant Trauma and Orthopaedic Surgeon at York Hospital since 2022, with a private practice at Nuffield Health York and Ramsay Clifton Park. I completed two specialist knee fellowships at Wrightington Hospital, in Soft Tissue Knee Surgery and Lower Limb Arthroplasty, and I set up the acute knee and soft tissue knee service.
