Injection Therapy

Overview

Knee injections can be a valuable treatment option for conditions such as osteoarthritis, meniscal tears, and cartilage injuries.  

They are often used alongside other treatments – such as physiotherapy, activity modification, or in some cases surgery – with the primary aim of reducing pain, improving function, and supporting recovery. 

There are several categories of injections: 

Types of injections

Steroid (cortisone) injections

Contain a synthetic form of cortisol, a naturally occurring hormone with powerful anti-inflammatory effects. They can reduce inflammation in the knee and provide significant short- to medium-term pain relief. 

Hyaluronic acid (“gel”) injections

Hyaluronic acid is a natural component of joint cartilage and fluid, helping to lubricate and cushion the joint. Injections aim to restore some of this lost lubrication, which can reduce stiffness and improve comfort during movement. 

Platelet rich plasma (PRP)

PRP is prepared from your own blood, which is processed in a centrifuge to concentrate platelets and growth factors that support tissue repair. When injected into the knee, PRP may help promote healing and reduce symptoms. 

Stem cell injections

Stem cell therapy often involves harvesting a sample from bone marrow (bone marrow aspirate concentrate) or fat tissue (adipose-derived cells). The sample is processed to concentrate healing proteins and a small number of stem cells, which are then injected into the knee to support tissue repair and regeneration.
