Cartilage regeneration
NanoACi
A non-arthroscopic Seed, Soil and Signal pathway using an auricular-cartilage micrograft, collagen scaffold and platelet-rich fibrin.
Tissue-first care for cartilage, meniscus, tendon and ligament damage, combining advanced regenerative pathways with specialist surgery when structure must be corrected first.
Verified across three networks
Professor Lee's regenerative framework
Seed. Soil. Signal.
Start with the tissue and its mechanical job—not a generic injection. RegenRepair™ combines patient-derived biology, a collagen scaffold and a biological signal in tissue-specific pathways for cartilage, meniscus, tendon and ligament damage.
Priority treatments
Four distinct options, with different targets and evidence. Suitability starts with diagnosis and imaging—not whichever name is most familiar.

Cartilage regeneration
A non-arthroscopic Seed, Soil and Signal pathway using an auricular-cartilage micrograft, collagen scaffold and platelet-rich fibrin.

Tendon regeneration
A tendon-specific pathway combining autologous fibroblast-rich micrografts, collagen Soil, platelet-rich fibrin Signal and progressive loading.

UK-exclusive access
An injectable, cell-free type-I collagen scaffold for selected focal cartilage defects.

Knee osteoarthritis
A single-dose polyacrylamide hydrogel injection used to treat symptoms of knee osteoarthritis.

STARR is the cartilage-preserving ACL repair pioneered by Professor Paul Lee. No tendon graft taken from your leg, recovery in six weeks to three months, and the ligament you were born with stays where it belongs.

Most patients arrive thinking the only path is replacement. We see your joint as a spectrum of choices, and replacement is the last resort, not the first.
Protect what you still have. Targeted injections and treatments that slow cartilage wear, manage arthritis, and keep your joint working.
Fix specific damage. A torn meniscus, a damaged ligament, a kneecap problem. Procedures that restore what is broken — time matters.
Rebuild damaged cartilage. Advanced biological treatments that stimulate your body to grow new tissue. Several available only at London Cartilage Clinic.
When other options are exhausted, replacement restores function — but only after we have explored every alternative.

Stem Cell / Medicinal Signaling Cell therapy has proven to be a very effective way of treating symptoms of degenerative conditions in the knee. If you’re looking for the best possible option regardless of the cost, Stem Cell / Medicinal Signaling Cell injections could be right for you.

Verified patient reviews
“I had ACL surgery a few months ago and was really worried about the recovery process. A friend recommended Professor Lee and I am so glad I followed her advice. The surgery was successful, and I recovered much faster than I expected.”

“Thank you, Professor, for reviewing all of my notes and going over the scans with me. I had consulted five private orthopaedic specialists, but none picked up on my knee plica. I am very grateful for your time and expertise.”

Clinical updates, cartilage treatment guidance, and recovery-focused articles from our specialist team.

Meniscal tears independently predict cartilage loss and osteoarthritis. Tear subtype, patient age, BMI, and alignment determine the rate of progression: posterior root tears in younger patients accelerate rapidly, whilst isolated degenerative tears may remain stable for years.

ChondroFiller injection is an ultrasound-guided, outpatient treatment for focal elbow cartilage defects: a collagen scaffold recruits the patient's own progenitor cells to regenerate tissue, avoiding cell culture.

ChondroFiller, a murine-derived collagen hydrogel, recruits the patient's own progenitor cells to repair focal cartilage lesions; hyaluronic acid viscosupplements like Durolane and Cingal restore joint lubrication in diffuse osteoarthritis without repairing tissue.
