A surgeon and operating team can perform your knee arthroscopy either in a hospital or outpatient surgical center.
After your surgery, you may have some soreness and discomfort in your knee.
You should come prepared with loose, comfortable pants or shorts to change into after the operation.

You may also be in a knee brace after your surgery.
Avoid tight-fitting pants that will compress the knee.
Your healthcare providers office will give you specific instructions.
Eating or drinking immediately before surgery can cause problems with anesthesia while you are undergoing the operation.
There are generally no specific medications that you should probably take to prepare for your knee arthroscopy.
You will also be given appropriate pain medication after the operation to help with your recovery.
