Don’t Let Cartilage Damage Limit Your Life

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.

“Repair first—keep the joint if we can.”

Why Healthy Cartilage Matters

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.

What Is ChondroFiller®?

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.

  • Shields the damaged zone from further wear
  • Attracts native cells into a 3D scaffold
  • Supports hyaline-like regeneration (not just fibrous scar)

One treatment. One step. A chance to keep your joint for the long term.

Frequently Asked Questions

Everything you want to know about ChondroFiller® at Liquid Cartilage.

What is ChondroFiller® and how does it support natural repair?

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.

How does it compare with other injections or joint replacement?

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.

What outcomes have been reported?

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.

Who is a good candidate?

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.

What is the procedure and recovery like?

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.

Patellofemoral Replacement Surgery for Kneecap Arthritis Relief

Patellofemoral replacement is a targeted partial knee surgery focusing on arthritis in the kneecap and thigh bone groove, offering pain relief while preserving healthy joint areas. Ideal for patients with isolated patellofemoral arthritis unresponsive to conservative treatments, it involves replacing damaged cartilage with precise implants. Under expert care at the London Cartilage Clinic, led by Professor Paul Lee, patients benefit from personalized assessment, careful surgical techniques, and structured rehabilitation. Recovery includes physiotherapy to restore function, with most resuming daily activities within months. Research highlights the importance of proper patella alignment and cautions on quadriceps strengthening to avoid complications. This procedure provides a focused solution for front-knee arthritis, improving mobility and quality of life with minimal risks when managed by experienced specialists.

Risks and Longevity of Modern Knee Replacement Implants

Total knee replacement (TKR) is a common solution for severe knee pain and mobility loss, notably in osteoarthritis. This article outlines the surgery's risks, such as infection, blood clots, and stiffness, and highlights the benefits of patellar resurfacing in reducing complications. Modern knee implants typically last 15 to 20 years, with longevity influenced by factors like activity level, weight, age, and surgical precision. Unicompartmental knee replacements (UKR) also show promising durability with lower revision risks. Recovery involves physiotherapy and lifestyle adjustments to maximize implant lifespan. Expert care, like at the London Cartilage Clinic, supports optimal outcomes. Understanding these elements helps patients make informed decisions and sets realistic expectations for surgery and recovery.
