Knee injections: PRP & hyaluronic acid

With cartilage damage, early osteoarthritis or persistent knee pain, joint-preserving treatment can help relieve symptoms and support joint function. Regenerative options include PRP/ACP injections (platelet-rich plasma) and hyaluronic acid injections.

At the AGON joint practice in Sterzing, Dr. Christian Coppola, specialist in orthopaedics and traumatology, first assesses whether an injection is right for you – and combines it with physiotherapy and targeted training where needed.

PRP/ACP (platelet-rich plasma)

A concentrate is obtained from a small amount of your own blood and injected into the joint. The body's own growth factors it contains are intended to calm inflammatory processes and support regeneration.

Hyaluronic acid

Hyaluronic acid is a natural component of joint fluid. An injection can improve joint lubrication and ease osteoarthritis symptoms.

Who is an injection suitable for?

Injections are mainly considered for cartilage damage, osteoarthritis and certain overuse problems. An accurate diagnosis is essential: Dr. Coppola assesses your symptoms, examination and imaging and discusses with you which therapy – conservative, regenerative or surgical – is right for you.

Cortisone injections are also used where indicated.

Frequently asked questions about PRP & hyaluronic acid

How does a PRP injection work?

After a blood sample is taken, the blood is processed and the resulting concentrate is injected into the affected joint under sterile conditions. The treatment is outpatient; the number of sessions is determined individually.

Is PRP or hyaluronic acid better?

That depends on your findings, symptoms and goals. The two treatments work in different ways. Dr. Coppola decides together with you after the examination which treatment – or combination – makes sense.

Can an injection replace surgery?

In some cases symptoms can be treated conservatively so well that surgery is not needed. With structural damage, such as certain meniscus or cruciate ligament injuries, surgery may be the better option. Dr. Coppola gives you honest, individual advice.

What else can I do?

Targeted physiotherapy and strength training stabilise the joint, and weight loss takes pressure off it. At AGON, physiotherapy, training therapy and nutrition counselling are tailored accordingly.
