Knee arthroscopy is keyhole surgery of the knee. A small camera is inserted into the joint through two small incisions, allowing the inside of the knee to be assessed and treated without open surgery. Meniscus surgery is one of the most common procedures performed this way.

The meniscus

The meniscus is a C-shaped piece of cartilage that sits between the thighbone and shinbone. There are two in each knee. They act as shock absorbers, distribute load evenly across the joint, and play an important role in long term knee health. Meniscus tears are among the most common knee injuries and can occur in people of all ages- through sport, sudden twisting movements, or gradual degeneration over time.

Symptoms typically include pain, swelling, stiffness, and mechanical symptoms such as catching or locking of the knee.

When is surgery indicated

Surgery is considered when symptoms have not resolved with non-operative management including physiotherapy, activity modification, and injection therapy. The decision to operate depends on the type of tear, the patient's symptoms, age, and activity level.

The procedure

Surgery is performed under general anaesthetic as a day procedure. Two small incisions are made and a camera is introduced into the joint. Depending on the tear, two approaches are available. In most cases the damaged portion of the meniscus is trimmed and removed- a meniscectomy. Where the tear configuration allows, the meniscus can be repaired and preserved. Dr Scaife will discuss the most appropriate option with you prior to surgery. Intraoperative images are taken and reviewed at your follow up appointment.

Recovery

Most patients are walking the same day and discharged within a few hours. Bandages should remain in place for 48 hours. Ice applied regularly in the first few days helps manage swelling and pain. Recovery depends on what was treated-  a meniscectomy carries a faster recovery than a repair, which requires a period of protected weightbearing to allow healing. A specific recovery plan will be outlined at your preoperative appointment.

Follow up

A postoperative appointment is scheduled 10 to 14 days following surgery.
