Injectable, Structural Regenerative Implant for Cartilage Care
Protect • Repair • Regenerate
Cartilage injuries can turn simple movement into a challenge. Without timely treatment, damage may progress and increase the risk of arthritis or future joint replacement.
At Liquid Cartilage, our goal is joint preservation and regeneration—not replacement. With ChondroFiller®, we deliver advanced, evidence-led care on Harley Street.

Cartilage provides the smooth, low-friction surface that lets your joints move comfortably. It doesn’t readily self-repair, but with the right scaffold and biological cues, regeneration is possible.
Act early to preserve more of what you have.

ChondroFiller® is an acellular, biologic collagen scaffold delivered in liquid form. Once placed, it gels within minutes, filling the defect and providing a framework that invites your cells to rebuild cartilage.
Think of it like “epoxy” for cartilage—without the plastic.
One treatment. One step. A chance to keep your joint for the long term.


ChondroFiller® sits in a different class— structural regenerative implant.
| Treatment | Analogy | What it Does | Limitation |
|---|---|---|---|
| HA (Hyaluronic Acid) | WD-40 | Improves lubrication for short-term comfort | Temporary; does not regenerate tissue |
| Arthrosamid® | Silicone | Acts on the synovium to reduce pain signalling | Not regenerative; literature notes complication rates up to 30% |
| ChondroFiller® | Epoxy resin | Fills defects, stabilises, and promotes true cartilage repair | Most robust injectable option for structural repair |

Injection, Keyhole, or Liquid Cartilage™

Precise and minimally invasive



Cartilage damage won’t reverse on its own—yet with the right plan it can be protected, repaired, and regenerated.
At Liquid Cartilage, you access world-leading science and a joint-preservation vision on Harley Street.

Everything you want to know about ChondroFiller® at Liquid Cartilage.
ChondroFiller® is an acellular collagen gel that fills cartilage defects and forms a scaffold for your own cells to regenerate healthy tissue. Unlike temporary injections, it supports hyaline-like restoration for smoother motion and protection long-term.
HA or Arthrosamid® may give short-term pain relief, while ChondroFiller® aims to rebuild cartilage. Compared with replacement, it preserves your natural joint and avoids prosthesis risks. Our approach is regenerate-first.
Studies show +30 IKDC in knees, +33 Harris Hip Score in hips, and improved ankle metrics. MRI (MOCART) typically reads 70–87. Globally, >19,000 cases support safety and function.
Best for focal defects up to 6 cm² in knees, hips, ankles, or small joints. Active younger patients often benefit, but older patients may qualify if surrounding cartilage is stable.
Delivered via precise injection or keyhole surgery. The gel sets in minutes. Expect partial weight-bearing ~6 weeks, steady return to cycling/swimming, and most sports around ~12 months alongside specialist rehab.
Harley Street location; UK ICRS Centre of Excellence. Led by Prof. Paul Lee, with advanced options like Liquid Cartilage™ (ChondroFiller® + cells) to prioritise preservation.
Discover what makes ChondroFiller® unique at Liquid Cartilage.

ChondroFiller is a collagen scaffold injected into ankle cartilage defects to create a biological matrix that triggers the body's own repair cells to migrate and remodel the tissue. The procedure is single-stage and outpatient, typically lasting 30 to 45 minutes.

An ACL rupture instantly compresses cartilage and bone where the tibia meets the femur as the tibia rotates and shifts forward forcefully. This structural damage occurs independently of the mechanical instability that follows; progressive cartilage degradation subsequently unfolds over months as the joint loses restraint.

For patients with Grade III or IV hip osteoarthritis, ChondroFiller injection—an outpatient ultrasound-guided treatment using a collagen scaffold—offers an alternative to replacement by preserving the native joint and triggering the body's own cartilage regeneration.

Lesion size determines treatment success in talar osteochondral defects: bone marrow stimulation succeeds in nearly all cases below 15 mm average diameter, but only 3% of lesions at or above that threshold.

For focal osteochondral lesions of the talus larger than 15 mm, bone marrow stimulation alone succeeds only 3% of the time; ChondroFiller, an injectable collagen scaffold placed under ultrasound guidance, offers a non-surgical pathway using the patient's own repair cells—no general anaesthetic or surgical incision.

Anterior knee pain does not reliably indicate cartilage damage; symptoms correlate only loosely with structural grade, requiring imaging and functional testing for accurate diagnosis.
