Knee Joint Injections

Where patients either have suspected or proven pathology inside the knee joint, intra-articular injection of the knee may well prove beneficial.

What conditions can it be performed for?
Knee injection may provide symptom relief in cases of:

What is injected?
A variety of different substances can be injected into the knee joint. A mixture of local anaesthetic plus steroid is often injected into the joint. The local anaesthetic gives rapid pain relief, although this wears off quite quickly. This makes it more comfortable for the patient and lets your doctor know if all the pain is coming from the knee joint itself. Steroid (also sometime called cortisone) act as a very powerful anti-inflammatory, although it acts just locally, within the joint.


How is it done?
To guarantee the correct needle placement the needle is guided into the knee joint under X-ray control. Once the needle appears to be in the correct position, a dye is then injected to make sure that the tip of the needle is actually inside the joint. The local anaesthetic and steroid or hyaluronic acid can then be injected into the joint.



Does it work?
Intra-articular injection into the knee is not going to cure things such as arthritis within the joint. However, it will settle down inflammation and offer good pain relief for a reasonable length of time, although this can range from anywhere between a few weeks up to several months or years depending on what pathology is present and how severe that pathology might actually be.
