ACi and MACi
The established search terms for cell-based cartilage regeneration. Professor Lee uses them as the familiar reference point when explaining the newer non-surgical and surgical pathways.

International patients · UAE
Patients from Dubai, Abu Dhabi and across the United Arab Emirates travel to London Cartilage Clinic for NanoACi, the wider Nano family, STACi, ChondroFiller, Mytocel MSK and expert ACi or MACi assessment with Professor Paul Lee.

London is an established destination for private patients from the United Arab Emirates, with direct premium air links from both Dubai and Abu Dhabi. At London Cartilage Clinic the reason to travel is access to a concentrated set of advanced joint-preserving options, delivered by Professor Paul Lee rather than passed between different teams.
Many patients begin by searching for ACi or MACi. Those established treatments remain an important reference point. The assessment also explains where non-arthroscopic NanoACi, the tissue-specific Nano family, the Structure-led surgical STACi pathway, ChondroFiller or standalone Mytocel MSK may fit the actual damage more precisely.

Why patients travel for treatment
Patients from the United Arab Emirates often arrive searching for ACi or MACi because those are the best-known cartilage cell treatments. They remain important. The assessment also shows where NanoACi, the wider Nano family, the Structure-led STACi pathway, ChondroFiller or Mytocel MSK may fit more precisely.

Non-surgical RegenRepair™
NanoACi for cartilage, NanoAMi for meniscus, NanoATi for tendon and NanoALi for ligament adapt Seed, Soil and Signal to the tissue being treated.
Surgical RegenRepair™
When alignment, stability or the damage pattern needs surgery, STACi addresses Structure before adding the Seed, Soil and Signal cartilage-regeneration biology.
Standalone or within a pathway
Mytocel MSK provides living autologous micrografts; ChondroFiller provides a collagen scaffold. Each has a standalone role and both sit within Professor Lee’s wider regenerative toolkit.
Been told replacement is your only option?
Some patients contact London Cartilage Clinic after being offered replacement or being told that cartilage regeneration is no longer an option. A joint-preserving route may still be worth assessing, but it depends on imaging, alignment, stability, the distribution of wear and the patient’s goals.
NanoACi is considered where a non-arthroscopic pathway is realistic. STACi is considered where the cartilage biology also needs surgical work to restore Structure. Where replacement is the correct treatment, Professor Lee will say so clearly.
Every alternative-to-replacement statement is a clinical judgement made only after a full assessment. Suitability depends on your individual case.

Dubai and Abu Dhabi both have frequent direct services to London. Imaging review and virtual consultation take place first so the clinical plan and length of stay are clear before travel.
Direct flights connect Dubai and Abu Dhabi with London in roughly seven to eight hours. A chauffeur transfer can be coordinated from the airport.
Share recent imaging before a virtual consultation with Professor Lee so the trip is based on a defined clinical question.
The Landmark London, chauffeur transfers, appointments and early recovery can be coordinated as one itinerary for the patient and accompanying family.
Return travel is planned around mobility, the procedure and individual blood-clot risk—not around a generic number of days.
Visiting us
66 Harley Street
London W1G 7HD
United Kingdom
A partner hospital on Weymouth Street, a few minutes from Harley Street. Imaging is arranged for you as part of your pathway.
Central London, a short walk from Regent’s Park, Oxford Circus and Bond Street underground stations.
Costs and insurance
Treatment is quoted and paid in pounds sterling, with the bank or card provider converting from UAE dirhams. A personalised written estimate follows clinical assessment.
Private insurance and government or employer sponsorship vary. London Cartilage Clinic does not assume approval: any guarantee of payment, pre-authorisation or reimbursement must be confirmed in writing before travel. Otherwise the pathway is direct pay, with an itemised invoice supplied for any later claim.

Authority
International patients are usually choosing between a small number of world specialists, so the surgeon matters more than any single treatment. Your consultation, your treatment and your follow-up are all with Professor Paul Lee.
International patients · United Arab Emirates
Patients commonly arrive asking about ACi or MACi. Professor Lee assesses those established options alongside NanoACi, the wider RegenRepair™ Nano family, the Structure-led STACi surgical pathway, ChondroFiller and Mytocel MSK. The recommendation follows the tissue and damage pattern, not the treatment name used in the initial search.
Yes. Recent scans and reports can be shared before a virtual consultation with Professor Lee. This helps determine whether travel for examination or treatment is worthwhile before flights and accommodation are booked.
Yes. The concierge can coordinate an appropriate hotel base, airport and clinic transfers and the treatment timetable around an accompanying family member. Exact arrangements are confirmed for the individual itinerary.
Cover is not assumed. Private insurance, employer cover and government sponsorship all require their own approval. Obtain written pre-authorisation or a guarantee of payment before travel; otherwise treatment is direct pay and the clinic can provide an itemised invoice.
Wherever you are travelling from, the first step is the same. Talk it through on a discovery call, or have a virtual consultation with Professor Lee before you plan any travel.
