Second Opinion for Hip and Knee Problems in Surrey and South West London

Unsure about the advice you have been given? An independent review of your diagnosis, scans and options, at your own pace.

Would a second opinion help you?

A second opinion is a fresh, independent assessment of your hip or knee problem by another specialist. It can confirm the advice you already have, offer another option, or simply give you the confidence to decide.

Mr Ashwin Unnithan is a Consultant Orthopaedic Surgeon specialising in hip and knee surgery, including revision of hip and knee replacements. He listens to your concerns, examines you and reviews your existing scans and letters with you. You will leave with a clear explanation of what he has found and what he would advise.

Asking for a second opinion is a normal part of making a decision about your health. It does not mean you have lost faith in your current surgeon.
