Knee injections aim to reduce pain, restore movement, and create the conditions for rehabilitation to work. They are not a substitute for strength and load management — but used well, they can make a meaningful short to medium term difference to those who respond to them.
THE OPTIONS
Types of Knee Injection
There are many different types of injections, all claiming different modes of action, each with their own risk profile. Efficacy and duration of relief varies for each person.
‘An injection aims to create a window of symptom relief in which the real work of recovery can begin. It does not cure the underlying problem.’
AT A GLANCE
Comparison
BEFORE CONSIDERING AN INJECTION: Ask your clinician: what is the injection intended to achieve, how will we know if it has worked, and what rehabilitation will follow it? An injection without a rehabilitation plan is a short-term measure, not a treatment.
