Arthroscopy of the Knee
This webpage will give you information about an arthroscopy
of the knee. If you have any questions, you should ask your GP or
other relevant health professional.
What is an arthroscopy of the knee?
An arthroscopy (also called ‘keyhole’ surgery) allows your
surgeon to see inside your knee using a camera inserted through
small cuts in the skin. They can diagnose problems such as a torn
cartilage, ligament damage and arthritis (see figure 1).

What are the benefits of surgery?
The main benefit of surgery is to confirm exactly what the
problem is and in many cases to treat the problem at the same
time.
Are there any alternatives to surgery?
Problems inside the knee can often be diagnosed using a magnetic
scan (MRI scan). However, you may then need an arthroscopy to treat
the problem.
What does the operation involve?
A variety of anaesthetic techniques are possible. Your surgeon
will examine the inside of your knee. They will wash out any loose
material caused by wear of the joint surfaces. It is usually
possible for your surgeon to trim or repair a torn cartilage
without needing to make a larger cut.
What complications can happen?
1 General complications of any operation
- Pain
- Infection in the surgical wound
- Unsightly scarring
- Blood clots
2 Specific complications of this operation
- Bleeding into the knee
- Developing a lump under the wound
- Infection in the knee joint
- Severe pain, stiffness and loss of use of the knee (Complex
Regional Pain Syndrome)
How soon will I recover?
You should be able to go home the same day.
It is common for the knee to be a little swollen for a few
weeks. Walking can be uncomfortable.
Most people make a good recovery and can return to normal
activities. However, further cartilage tears occasionally
happen.
Summary
An arthroscopy allows diagnosis and treatment of some common
problems affecting the knee, without the need for a large cut in
the skin. This may reduce the amount of pain you feel and speed up
your recovery after surgery.
