What is Knee Arthroscopy?

Knee arthroscopy is a procedure in which the surgeon inserts a small camera, called an arthroscope, through a tiny incision to view the inside of the knee on a screen.

Thin instruments pass through other small incisions to treat what is found.

It is used for specific problems such as a meniscus tear that catches the knee, loose fragments of cartilage, or to prepare a defect for restoration. It is not a treatment for general arthritis pain.

Because the incisions are small, many people go home the same day. The value of arthroscopy depends on matching it to the right problem.

What happens during Knee Arthroscopy, step by step?

Under anesthesia, the surgeon fills the knee with fluid, inserts the arthroscope, and inspects the joint.

Depending on findings, the surgeon may trim or repair a meniscus, remove loose bodies, or address a cartilage defect. The incisions are closed with a stitch or small strips. Dr. McMillan will explain what was found and done after the procedure.

What is recovery like after Knee Arthroscopy?

Many people go home the same day and walk with support soon after.

Recovery depends heavily on what was done inside the knee. A simple trimming often allows a return to light activity within a couple of weeks, while a repair requires a longer, protected course, according to general guidance from the American Academy of Orthopaedic Surgeons. These are ranges, not promises. Your surgical team will give you a plan based on your procedure.
