The Procedure

Q: What does knee arthroscopy involve?

A patient is fully sedated. The surgeon makes several tiny incisions around the knee, injects a visualizing fluid to clean the joint and inserts a fiber optic camera into the joint that sends detailed images of the site to a television monitor. The orthopaedic surgeon can see throughout the joint to determine what steps are needed to repair the knee. 

The surgeon may have to graft tissue to the ligament to make the repair and rebuild the ligament. In some cases where there are multiple torn ligaments, you may have to undergo additional procedures over time to allow for the joint to be rebuilt.


Q: How many incisions are made?

Three to four tiny incisions are made around the knee.

Hospital Stay

Q: How long do I stay in the hospital?

Patients will normally be able to go home the same day, but in some cases, there may be an overnight stay.

Recovery Time

Q: What is the recovery time?

Most patients feel better after the first week, but may have to remain on crutches until the doctor releases them. For full recovery, it typically takes several months for the knee joint to heal. Your doctor can advise on your activities and when you can return to work or school.
