Hyaluronic Acid Knee Injection in London
Effective, Non-Surgical Relief for Knee Osteoarthritis and Knee Pain
If you’re living with joint pain, stiffness, or reduced mobility caused by knee osteoarthritis, hyaluronic acid injections offer safe, proven relief. This simple, non-surgical procedure helps restore lubrication, cushioning, and comfort in the knee joint — allowing you to move more freely again.
What Is Hyaluronic Acid?
Sodium hyaluronate (also known as hyaluronic acid or hyaluronan) is a natural substance produced throughout the body in large quantities when we are young — wherever moisture is stored or lubrication between tissue layers is needed to reduce friction.
It is found inside the eyeball, in the tear film, joint cartilage, and synovial fluid, as well as in the mucous membranes and skin, which can consist of up to 55% sodium hyaluronate.
Under an electron microscope, its long molecular chains resemble a dish of spaghetti — a dense, elastic mesh that stays flexible despite its structure.
Hyaluronic acid performs several vital functions:
- Storage: Absorbs and retains large quantities of moisture.
- Lubrication: Reduces friction between cartilage and tissue layers.
- Nutrient transport: Acts as a carrier for essential nutrients within the joint.
- Inflammation control: Filters inflammatory molecules to reduce pain.
As we age, natural hyaluronic acid levels decline, leading to stiffness and discomfort. Hyaluronic acid injections help restore this balance by stimulating cells in the joint lining to produce more of their own hyaluronic acid, improving lubrication and function.
Hyaluronic Acid and Knee Joint Health
Sodium hyaluronate is a crucial component of synovial fluid, the natural lubricant that allows smooth, pain-free movement in the knee and hip joints. In healthy joints, it functions as a lubricant, shock absorber, and filter, regulating the movement of cells and larger molecules.
In people with knee osteoarthritis, this balance becomes disrupted, leading to reduced viscosity, inflammation, and pain. By replenishing the joint’s hyaluronic acid levels, injections help restore comfort, flexibility, and protection.

Restoring Comfort and Movement Naturally
Hyaluronic acid injections provide a proven, non-surgical way to manage knee osteoarthritis and joint pain. Under the care of Consultant Orthopaedic Surgeon Dr Arjuna Imbuldeniya, the treatment is delivered with precision and evidence-based expertise — helping patients regain mobility, reduce inflammation, and delay the need for more invasive procedures.
Key Information About Private Hyaluronic Acid Knee Injections in London
Viscosupplementation is the process of injecting sodium hyaluronate into the knee joint to restore lubrication and cushioning. It helps reduce pain, stiffness, and inflammation while improving joint function and movement.
We use OSTENIL® PLUS, a highly purified, fermentation-derived form of sodium hyaluronate. It contains no animal proteins, meaning allergic reactions are extremely unlikely.
The injection is performed by Dr Arjuna Imbuldeniya under ultrasound guidance in the outpatient clinic. After local anaesthetic is applied, sodium hyaluronate is injected directly into the synovial joint space. The procedure causes minimal discomfort and takes just a few minutes.
Patients typically walk out of the clinic and resume normal activity the same day. Some may experience mild stiffness or swelling for 24–48 hours, which usually settles quickly.
Potential Side Effects and Risks
Hyaluronic acid injections are generally very safe. Mild side effects may include temporary swelling, warmth, or tenderness at the injection site. In rare cases, allergic reactions can occur, but the absence of animal proteins in OSTENIL® PLUS makes this extremely unlikely.
All patients are assessed beforehand to ensure the treatment is suitable. Any potential risks will be discussed with Dr Imbuldeniya during your consultation.
What to Expect from Your Hyaluronic Acid Knee Injection
Every stage of your treatment is designed for safety, precision, and comfort.
-
Initial Consultation During your consultation with Dr Arjuna Imbuldeniya, your symptoms, medical history, and treatment goals will be reviewed. Imaging may be arranged to confirm the severity of osteoarthritis and suitability for viscosupplementation. -
Tests and Assessment If required, diagnostic imaging such as X-ray or ultrasound will help visualise joint space, cartilage wear, and inflammation. This ensures the injection is placed with accuracy and tailored to your individual needs. -
The Procedure The injection is performed under local anaesthetic in a clean outpatient environment using high-resolution ultrasound guidance. Sodium hyaluronate is injected directly into the synovial capsule, restoring lubrication and shock absorption. You can return home immediately and resume normal activities shortly afterwards.
