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.

Injected collagen scaffolds recruit tissue-repair cells in worn knees and generate measurable functional improvement within 12 months; whether they delay joint replacement remains unproven, and patient selection — single-compartment Grade III disease rather than multi-compartmental Grade IV — determines candidacy.

Advanced osteoarthritis involves simultaneous cartilage loss and synovial membrane damage. A dual-injection protocol targets both: ChondroFiller uses acellular matrix-induced chondrogenesis to regenerate cartilage, whilst Arthrosamid integrates a cross-linked hydrogel into the synovial lining.

Repeated ankle sprains cause permanent cartilage damage through direct impact trauma—the talus slams against joint surfaces—and through progressive wear from abnormal loading when ligaments are stretched.

Focal cartilage defects differ from osteoarthritis: when damage is confined to one region with intact surrounding tissue, joint integrity is preserved and regenerative treatment becomes possible — but early intervention is essential to forestall progressive degeneration.

Eligibility criteria, not clinical ranking, determine which cartilage-repair option applies: MACI requires four simultaneous NHS gates; ChondroFiller injection—cheaper and single-stage—is available for any defect size, multiple joints, and patients with prior cartilage procedures.

ChondroFiller polymerises inside cartilage defects to form a scaffold that recruits the body's own cells for tissue repair; published trials show 30-point functional gains in younger patients with focal defects, though the injection pathway remains untested in controlled studies.
