Best Injection for Knee Arthritis: Which Knee Injection Could Be Right for You?
Finding the Best Injection for Knee Arthritis
There are several different types of knee injections available, and they do not all work in the same way. Corticosteroids, hyaluronic acid, platelet-rich plasma (PRP) and newer treatments such as Arthrosamid® each have different characteristics and may be considered in different circumstances.
This means there is not one treatment that can automatically be described as the best injection for knee arthritis for every patient. The right option depends on your symptoms, the condition of your knee, previous treatments and what you are hoping to achieve.
At Royal Liver Orthopaedics, our dedicated orthopaedic centre within The Royal Liver Building in Liverpool, specialist doctors assess patients with knee osteoarthritis and discuss appropriate treatment options. Royal Liver Orthopaedics works alongside Cosmetic Surgery of The Royal Liver Building, a CQC-registered independent healthcare provider.
For suitable patients, Arthrosamid knee injection treatment is carried out following a private consultation and individual suitability assessment.
Why Are Knee Injections Used for Arthritis and
Finding the Best Injection for Knee Arthritis.
Knee injections can form part of a wider treatment plan for people experiencing symptoms associated with osteoarthritis.
Knee osteoarthritis can cause pain, stiffness and reduced mobility. Over time, symptoms may begin to interfere with everyday activities such as walking, using stairs, exercising or standing for prolonged periods.
Depending on your individual circumstances, treatment may include physiotherapy, strengthening exercises, activity modification, weight management where appropriate and pain management alongside injectable treatments.
Knee injections are therefore not necessarily a standalone solution. They are one of several approaches that may be discussed as part of an individual’s overall treatment plan.
If you want to understand the different types of injections available, our guide to Knee Injections for Arthritis provides further information.

Steroid Knee Injections
Finding the Best Injection for Knee Arthritis
A steroid injection works differently from Arthrosamid. Corticosteroids are primarily intended to reduce inflammation and associated symptoms rather than provide a physical hydrogel within the joint.
Some patients may experience useful short-term relief following a steroid injection, although the duration and extent of improvement can vary.
Whether a steroid injection is appropriate depends on the individual’s symptoms, medical history and previous treatment.
If your priority is longer-term symptom management, your specialist doctor can discuss other available options and explain the potential benefits and limitations of each treatment.

Finding the Best Injection for Knee Arthritis –
Hyaluronic Acid Knee Injections
Hyaluronic acid occurs naturally within the body and forms part of the synovial fluid found within joints. Injectable preparations are designed to support the joint environment and may help some patients manage symptoms.
Results can vary considerably between individuals. The severity of osteoarthritis, general health and other factors can all influence how a patient responds.
When searching for the best injection for knee arthritis, it is therefore important to consider the individual rather than simply comparing treatments based on their names.
A specialist assessment can help determine whether hyaluronic acid or another treatment may be appropriate.
PRP for Knee Osteoarthritis
Finding the Best Injection for Knee Arthritis
PRP is produced using a sample of the patient’s own blood. The blood is processed to concentrate platelets before the resulting preparation is used as an injectable treatment.
PRP is used in a variety of musculoskeletal settings. However, its suitability and effectiveness can vary depending on the condition being treated and the individual patient.
For this reason, PRP should be considered as one possible treatment option rather than automatically being regarded as the best injection for knee arthritis.
A consultation allows your specialist doctor to consider your circumstances and explain whether PRP or another treatment may be appropriate.
Arthrosamid Knee Injection: A Different Approach
Arthrosamid® takes a different approach to many traditional knee injections.
It is a non-absorbable hydrogel containing 2.5% polyacrylamide hydrogel. Once injected into the knee joint, it is designed to remain within the joint and integrate with the synovial tissue.
The hydrogel is intended to provide a cushioning effect within the joint and support the management of symptoms associated with knee osteoarthritis.
This differs from injections that are designed to be absorbed by the body over a shorter period.
For suitable patients, Arthrosamid may therefore be considered when looking for a non surgical knee treatment option and a longer-lasting approach to managing osteoarthritis symptoms.
You can find out more about the treatment on our dedicated Arthrosamid Knee Injection page.
Which Knee Injection Is Best for Arthritis?
Finding the Best Injection for Knee Arthritis
There is no universal answer to the question of which is the best injection for knee arthritis.
Each treatment has a different purpose and mechanism of action.
Steroid injections are generally used to help manage inflammation and associated symptoms.
Hyaluronic acid injections are intended to support the joint environment, while PRP uses concentrated platelets obtained from the patient’s own blood.
Arthrosamid is different because the polyacrylamide hydrogel is designed to remain within the knee joint.
For suitable patients, this may provide a longer-lasting treatment approach. However, this does not mean that Arthrosamid is automatically the right choice for every person with knee osteoarthritis.
The severity of your condition, your symptoms, previous treatments, general health and treatment goals all need to be considered.
Our guide to How Long Do Knee Injections Last? explores the expected duration of different injectable treatments in more detail.
Who May Be Suitable for Arthrosamid?
It may be discussed with patients experiencing:
- Persistent knee pain or discomfort
- Knee stiffness
- Reduced mobility
- Symptoms associated with osteoarthritis
- Ongoing symptoms despite conservative treatment
- A desire to explore non-surgical options
Your specialist doctor will consider your symptoms, medical history, previous treatment and individual treatment goals before determining whether the treatment is appropriate.
The aim is not simply to identify the best injection for knee arthritis in general. Instead, the focus is on identifying whether there is an appropriate treatment option for your particular circumstances.
Can Knee Injections Delay Knee Replacement Surgery?
For some patients, injectable treatments may form part of a strategy for managing symptoms before more invasive treatment is considered.
This is one reason why patients with knee osteoarthritis often research non-surgical knee treatment and alternatives to knee replacement surgery.
Arthrosamid may be considered for suitable patients who want to explore a non-surgical option. It may help some patients manage symptoms and potentially delay the need for surgery.
However, no injectable treatment can guarantee that a patient will not eventually require knee replacement surgery.
Where osteoarthritis is advanced or symptoms significantly affect quality of life, surgical treatment may ultimately be considered more appropriate.
Our article on Alternatives to Knee Replacement Surgery explores some of the options that patients may consider before proceeding to joint replacement.
