Is arthroscopy used for a torn meniscus?

Yes. Knee arthroscopy is commonly used to treat certain meniscus tears. During the procedure, the surgeon inserts a small camera called an arthroscope through a small incision. The camera shows the inside of the knee on a monitor, while fine surgical instruments are inserted through other small incisions to treat the damaged meniscus.

The surgeon may repair the tear with stitches or remove only the damaged portion of the meniscus. Repair is more likely when the tear is in an area with a good blood supply and the tissue has a reasonable chance of healing. A partial meniscectomy may be considered when the torn section is unlikely to heal or is causing persistent locking, catching, or pain. Not every torn meniscus needs surgery. Rest, activity changes, medicines, and physiotherapy may be tried first, particularly when symptoms are mild or the tear is related to age-related wear.

Recovery depends on what is done during arthroscopy. Patients often recover faster after removal of a small damaged portion than after a meniscus repair, because repaired tissue needs time to heal. Dr. Atul Mishra reviews the patient’s symptoms, examination findings, activity needs, and MRI before deciding whether arthroscopy is appropriate and whether the meniscus should be repaired or trimmed.
