Liquid cartilage injections

Liquid cartilage injections involve injecting a collagen-based solution directly into a damaged joint. This offers advanced cartilage repair, promoting natural healing and regeneration.

Nature of liquid cartilage injections

Liquid cartilage injections are a non-surgical treatment designed to restore damaged knee cartilage and relieve pain. These injections contain a synthetic or biologically derived substance designed to mimic natural cartilage, providing lubrication and cushioning in the joint. By replenishing the cartilage, liquid cartilage injections help reduce friction, improve joint movement, and slow further degeneration.

Common uses of liquid cartilage injections

Knee joint problems treated with liquid cartilage injections are typically caused by:

Osteoarthritis: Cartilage wear leads to pain, stiffness, and reduced mobility.

Previous knee injuries: Trauma to the knee can result in cartilage damage and joint instability.

Age-related degeneration: As we age, cartilage naturally deteriorates, causing joint discomfort.

Overuse: Repetitive activities can accelerate cartilage breakdown, leading to pain and inflammation.

Chronic inflammation: Long-term inflammation can lead to cartilage degradation and knee joint issues.

Diagnosis for liquid cartilage injections

Diagnosis for liquid cartilage injections starts with a clinical evaluation to assess knee pain, swelling, and reduced range of motion. Imaging tests like X-rays or MRIs help identify cartilage damage, joint space narrowing, and other knee issues.

If conservative treatments fail and cartilage damage is confirmed, liquid cartilage injections may help restore joint function and relieve pain, especially in osteoarthritis or cartilage degeneration cases.

Treatment overview

Liquid cartilage injections aim to replace parts of the joint that have been damaged due to injury or arthritis. This treatment can be done through an injection or, in some cases, surgery (such as arthroscopy), depending on the severity of the damage.

The process involves gaining access to the affected joint by arthroscopy (keyhole surgery). Once the defect is found, the collagen matrix is introduced. This matrix acts like scaffolding, stimulating and providing support for the new, healthy cartilage to grow around.

Liquid cartilage injections are a great solution for those with ongoing knee or ankle pain, who are looking for a low-risk, fast healing time procedure.

Benefits

Minimally-invasive, can be performed via keyhole surgery

Ideal for small and difficult-to-reach injures/defects

Faster recovery time (compared to surgical treatments)

Helps restore the joint’s normal function

Frequently asked questions

How long until I notice results?

You should notice improvements in as few as 4-6 weeks, with benefits lasting as long as 6-12 months in most cases.

Several factors will impact the effectiveness and overall timeline, including how badly the cartilage is damaged, your general health and age, as well as your diet, lifestyle and adherence to aftercare following your treatment.

Like every injection, one of the risks of liquid cartilage therapy is infection. However, this is rare due to the sterile techniques and environment we practice in. There is also a very small chance you may be allergic to the materials used in the injection.

This treatment is typically suitable for individuals with degenerative joint disease (such as osteoarthritis), cartilage tears, or joint damage caused by injury, age-related wear, overuse, or chronic inflammation.
Liquid cartilage injections are a non-surgical treatment used to repair damaged cartilage in joints such as the knee or ankle. They involve injecting a collagen-based solution that mimics natural cartilage, helping to lubricate the joint, reduce pain, and promote healing.
Yes. Patients can self-pay using bank transfers, credit/debit cards, or cash. Interest-free instalment plans are available through GoCardless, and finance options can be accessed via Kandoo. Limited private medical insurance coverage may also apply.
