What is knee arthroscopy

You may have knee arthroscopy to investigate problems such as inflammation or injury, or to repair damaged tissue and cartilage. It’s also used to take small tissue samples (biopsies), which can help to diagnose problems such as infection.

An arthroscopy can take from 30 minutes to over an hour, depending on how much work your surgeon needs to do inside your knee joint. Once the anaesthetic has taken effect, your surgeon will make small cuts in the skin around your knee joint. He or she will pump sterile fluid into your joint to help produce a clearer picture and then insert the arthroscope .Compared with open surgery, arthroscopy has a faster recovery time.

Your surgeon will examine your knee joint by looking at images sent by the arthroscope to a monitor. If necessary, he or she can insert instruments to repair damage or remove material that interferes with movement or causes pain in your knee.
