Meniscus Repair

What Is the Meniscus?

The meniscus is a C-shaped piece of cartilage in the knee that acts as a cushion between the thighbone (femur) and shinbone (tibia). Each knee has two menisci – one on the inner side (medial) and one on the outer side (lateral). They help absorb shock, stabilize the joint, and protect the knee from wear and tear.

What Is Meniscus Repair?

Meniscus repair is a surgical procedure to preserve and stitch back the torn cartilage rather than removing it. This is usually done arthroscopically (through small incisions using a tiny camera and instruments). Repairing the meniscus helps maintain knee function and reduces the risk of arthritis later in life.

When Is It Needed?

Meniscus repair may be recommended if:

You have a tear in the meniscus that causes pain, swelling, or locking of the knee.
The tear is in a region with good blood supply (which allows healing).
You are young or active and want to preserve long-term knee health.
Non-surgical treatments (rest, physiotherapy, medications) have not relieved symptoms.

The Procedure Step-by-Step

Evaluation – MRI and physical exam confirm the type and location of the tear.
Arthroscopy – A small camera is inserted into the knee for visualization.
Repair– The torn edges of the meniscus are stitched together using special devices.
Closure – Small incisions are closed, and the knee is bandaged.

Recovery and Rehabilitation

Hospital stay: Usually same-day or overnight.
Weight bearing: Often limited for a few weeks to protect the repair.
Physiotherapy: Essential to restore movement and strengthen muscles.
Return to sports: Typically 4–6 months, depending on healing and rehab progress.

Benefits

Preserves natural knee cartilage.
Reduces risk of arthritis compared to meniscus removal.
Restores knee stability and function.
Better long-term outcomes for active patients.

Risks & Considerations

Not all tears can be repaired (depends on location and type).
Risks include infection, stiffness, or re-tear.
Healing takes longer than meniscectomy, requiring patience and commitment to rehab.

Key Message for Patients

Meniscus repair is a safe and effective way to preserve knee health after a meniscus tear. While recovery takes longer than simple removal, repairing the meniscus offers better long-term protection against arthritis and helps maintain natural knee function.
