Precision Joint Care

Private Knee Specialist and Consultant Knee Surgeon in London

I am Dr Arj Imbuldeniya, a consultant knee surgeon and private knee specialist in London, seeing patients in Mayfair, at Cromwell Hospital in Kensington, in Chiswick and in Brentford. I treat knee pain, sports injuries such as ACL and meniscus tears, cartilage damage and arthritis, starting with the least invasive treatment that will work and moving to precise, modern surgery when it is genuinely the right answer.

Knee care goes wrong in two directions: some people are operated on too soon, and others are kept away from an operation they urgently need. Seeing a surgeon who offers both routes is how you avoid either mistake. No two patients leave with the same plan, because your knee, your health, your work and your family are your own.

Knee specialist in central and west London

You can see me at four clinics across London: Lanserhof at The Arts Club in Mayfair, Cromwell Hospital in Kensington, Chiswick Medical Centre and Circle Syon Clinic in Brentford. Surgery takes place at Cromwell Hospital, The Lister Hospital in Chelsea and The Clementine Churchill Hospital in Harrow.

That puts a consultant knee surgeon within easy reach whether you live in central London, Kensington, Chelsea, Pimlico or Fulham, south-west London from Battersea, Clapham and Wandsworth to Putney, Barnes and Wimbledon, or west London across Hammersmith, Acton, Ealing, Chiswick, Richmond, Twickenham and Hounslow. Patients also travel from Harrow, Pinner, Watford, Bushey, Rickmansworth, Windsor, Reading, Surrey and Berkshire. Details of each venue are on my locations page.

When should you see a knee specialist?

See a knee specialist if your knee has given way, locked or swollen after an injury, if pain has lasted more than a few weeks despite rest and physiotherapy, or if arthritis is starting to limit your walking, sleep or sport.

Many people are unsure what kind of doctor to see for knee pain. A consultant orthopaedic knee surgeon can diagnose the cause, arrange an MRI where it adds something, and offer every option from rehabilitation and ultrasound-guided knee injections through to ACL reconstruction, meniscus repair, cartilage repair and robotic knee replacement. For wear and tear, start with my knee arthritis page.

How much does a private knee specialist cost?

A new private consultation with me costs £350 and a follow-up is £250. Knee injections range from £500 to £3,500, and surgeon's fees for knee surgery start at around £1,110.

Most insurers, including Bupa and AXA, cover consultations and treatment, and self-funding patients are always welcome. My full fee schedule is on the pricing page, and for replacement surgery see knee replacement cost. My team will give you a written estimate before anything is booked.

Frequently Asked Questions

Usually not. For most knee conditions, surgery is not the starting point. Many knee conditions improve with accurate diagnosis, targeted rehabilitation and biological or injection therapies. Surgery is only considered when non-operative treatment has been fully optimised and symptoms remain limiting.

A specialist knee surgeon treats conditions including meniscal tears, ligament injuries such as ACL damage, cartilage defects, patellar instability, tendon problems, early and advanced knee arthritis, and complex biomechanical or alignment issues.

A consultation includes a detailed discussion of symptoms, specialist clinical and biomechanical assessment, and review of imaging such as MRI. Where appropriate, further diagnostics are arranged and a personalised treatment pathway is outlined.

Consultant-led knee care is delivered in London, supporting patients across Central and West London. Consultations take place at Cromwell Hospital in Kensington, in Chiswick, at Circle Syon Clinic in Brentford and at Lanserhof Mayfair. Surgery takes place at Cromwell Hospital, The Lister Hospital in Chelsea and The Clementine Churchill Hospital in Harrow.

A consultant orthopaedic knee surgeon is the right specialist when knee pain follows an injury, keeps coming back or is limiting your life. A knee surgeon can diagnose the cause and offer every option, from rehabilitation and injections to surgery, so the advice is not limited to one treatment.

A new private consultation with me costs £350 and a follow-up is £250. Most insurers, including Bupa and AXA, cover the consultation.

Not if you are paying for yourself. Insurers often ask for a GP referral before they authorise the consultation, so check with your insurer first.

Seek urgent care if your knee is hot, red and swollen with a fever, if you cannot put weight on it after an injury, if it looks deformed, or if it is locked and will not straighten. See a knee specialist soon if it keeps giving way, swells repeatedly, or pain wakes you at night.

The commonest causes are arthritis, overload of the kneecap joint from changes in activity or weak hips, tendon problems, degenerative meniscus tears and, less often, inflammatory conditions such as gout. Where it hurts and when it hurts are the best clues to the cause.

Pain on bending often comes from the kneecap joint, the meniscus or arthritis. Pain at the front when squatting or on stairs points to the kneecap, while pain deep on one side with twisting suggests the meniscus. A knee that hurts more and more on bending is worth an assessment.

Pain behind the knee is commonly from a Baker's cyst, a hamstring or calf tendon problem, or a tear at the back of the meniscus. A painful, swollen calf with pain behind the knee needs urgent medical review to rule out a blood clot.

Pain on the inner side of the knee is often from early arthritis in the inner compartment, a medial meniscus tear, a strained medial ligament or irritation of the tendons just below the joint. An examination usually separates them.

Front-of-knee pain usually comes from the kneecap joint or the tendons above and below it, often linked to load, weak hips or changes in training. My anterior knee pain page explains the causes and treatment.

If knee pain has not clearly improved after a few weeks of sensible rest and exercise, or is getting worse, it is time to be seen. After an injury with swelling, locking or giving way, be seen sooner.

I see patients in Mayfair, at Cromwell Hospital in Kensington, in Chiswick and in Brentford, which covers central, south-west and west London. Book online, call 0207 859 4016 or email admin@ortholongevity.co.uk.

Look for a consultant whose practice is focused on the knee, who is on the GMC specialist register for trauma and orthopaedic surgery, and who can talk you through non-surgical options as well as surgery. Ask how often they perform the operation you are considering and what their results and complication rates are, and read verified patient reviews on independent sites such as Doctify. A good knee specialist should be as comfortable telling you that you do not need an operation as recommending one.
