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 isjoint preservation and regeneration—not replacement. WithChondroFiller®, 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, itgels 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 |

Precise and minimally invasive



Cartilage damage won’t reverse on its own—yet with the right plan it can beprotected, 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 restorationfor 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 orkeyhole surgery. The gel sets in minutes. Expectpartial weight-bearing ~6 weeks, steady return to cycling/swimming, and most sports around~12 months alongside specialist rehab.

Discover what makes ChondroFiller® unique at Liquid Cartilage.

Persistent joint pain with everyday tasks, stiffness, catching, or loss of strength after a sprain, fracture, or repeated throwing needs specialist review, because early cartilage damage still leaves room for joint-preserving treatment. In ankle, thumb base and throwing-elbow disease, stage and stability determine whether repair remains possible before end-stage collapse.

Unloader bracing can reduce pain in unicompartmental knee osteoarthritis for up to 52 weeks, but it only shifts load. High tibial or distal femoral osteotomy changes alignment when varus or valgus malalignment drives overload, while chondroplasty merely trims unstable cartilage flaps to ease catching.

Liquid Cartilage™, meaning ChondroFiller™, is an arthroscopic collagen matrix used for localised hip or ankle cartilage defects, not diffuse osteoarthritis. In a small 2021 hip cohort, 17 of 21 patients available at 3 to 5 years had good or excellent results, but ankle evidence remains thinner than for microfracture.

Cartilage repair choice is driven first by defect size, joint and damage pattern: smaller isolated lesions tend towards OATS or scaffold-based repair, while larger symptomatic defects more often need AMIC, MACI or OCA. In the knee, MACI outperformed microfracture at 2 and 5 years for larger defects.

Knee OCD has no single countdown clock; the preservation window is the stable-lesion stage before instability or detachment, with MRI and clinical assessment driving decisions. In children with open growth plates, stable lesions are often given a 3- to 6-month joint-preserving trial because healing remains plausible.

Liquid Cartilage™ is considered for a defined symptomatic cartilage defect treated arthroscopically, not for diffuse joint wear: ChondroFiller™ is a cell-free type I collagen scaffold placed into the defect and sets into a hydrogel in about 3–5 minutes.
