Knee Arthroscopy

What Is Knee Arthroscopy?

Knee arthroscopy is a diagnostic procedure used to determine the cause and nature of pain in the knee area.  The patient receives general anesthesia for the procedure.  The surgeon makes one or two small incisions around the patient’s knee and inserts an arthroscope connected to a television.  The latter provides adequate visibility for the surgeon to determine the source of the problem.   

If the patient’s cartilage is torn or if bone fragments are visible, the surgeon removes the torn section and fragments by inserting instruments through one of the incisions.  However, if the patient has torn a ligament, the doctor makes note of the extent of the damage to discuss potential treatment after the knee arthroscopy.  Patients suffering from arthritis often have their knee washed with saltwater, which tends to relieve symptoms for a few months.   

Once the knee arthroscopy is complete (and no other surgery is required), the surgeon closes the incisions with surgical tape or stitches.  The procedure usually does not necessitate a hospital stay, and patients are generally able to return home on the same day.  The bandages, dressing, and surgical tape typically remain in place for approximately 10 days.  Patients should not drive for up to 2 weeks after the knee arthroscopy.  Desk jobs, gentle exercise, and light work are usually fine after 1 week.  More strenuous activity might have to wait for a month or more, depending on the condition of the knee.Â
