How effective is partial meniscectomy for meniscus tear?

During arthroscopic surgery, the surgeon trims only the unstable or badly damaged portion of the meniscus and preserves usable tissue where possible. It may help when a torn fragment repeatedly catches, causes mechanical symptoms, or remains painful after examination and rehabilitation. It may not remove pain caused by knee arthritis, inflammation, ligament injury, or a tear that is better suited to repair.

The decision depends on the tear's location and shape, blood supply, age of the injury, knee stability, and the person's goals. A scan is interpreted alongside the symptoms and physical examination rather than used alone.

Discuss whether strengthening, activity changes, pain relief, or observation are reasonable first. If surgery is chosen, arrange transport, comfortable clothing, and help with early household tasks. Rehabilitation usually focuses on swelling control, restoring knee movement, activating the thigh muscles, and gradually rebuilding strength. Avoid twisting, deep squatting, or impact until your clinician allows progression.

Get prompt advice for a locked knee, inability to straighten the leg, rapidly increasing swelling, fever, wound drainage, severe calf pain, chest pain, or sudden breathlessness after treatment. A new injury with inability to bear weight also deserves assessment.

Ask what type and location of tear you have, whether repair or rehabilitation could preserve more meniscus, what symptoms surgery is expected to address, and how arthritis might affect the result. Request clear guidance on exercises, work, driving, and returning to sport.
