Meniscus Repair Surgery

Overview

The meniscus is a C-shaped cartilage in the knee that acts as a cushion between the thigh bone (femur) and shin bone (tibia). A meniscus tear is one of the most common knee injuries, often caused by sudden twisting motions, trauma, or degeneration due to aging.

Meniscus Repair Surgery is a minimally invasive procedure aimed at preserving the meniscus and restoring knee function by stitching the torn cartilage back together, rather than removing it.

Procedure of Meniscus Repair Surgery

Meniscus repair surgery is a minimally invasive arthroscopic procedure aimed at repairing torn knee cartilage to preserve joint function and prevent long-term damage like arthritis. Here’s what the procedure typically involves:

Step-by-Step Procedure:

1. Anesthesia>

The surgery is usually performed under spinal, regional, or general anesthesia, depending on patient needs and surgeon preference.

2. Arthroscopic Access

Small incisions (portals) are made around the knee.
A tiny camera (arthroscope) is inserted to give the surgeon a clear, magnified view of the joint.

3.Evaluation of the Tear

The surgeon examines the type, size, and location of the tear to determine if it can be repaired.
Tears in the outer third (red zone) of the meniscus, which has good blood supply, are more likely to heal after repair.

4. Tear Repair

Specialized instruments are inserted through the small incisions.
The torn edges of the meniscus are sutured together using absorbable stitches or suture anchors.
Sometimes bioabsorbable devices (such as arrows, darts, or screws) are used to hold the tissue in place.

5.Closure

Once the repair is complete, the instruments are removed.
The incisions are closed with stitches or surgical tape and the knee is bandaged.

6. Postoperative Care

The patient is monitored for a short period and usually discharged the same day.
Crutches and a knee brace may be provided to protect the repair during initial healing.

Advantages of Meniscus Repair Surgery:

Meniscus repair surgery focuses on preserving the natural cartilage in your knee, rather than removing it. When appropriate, it offers several long-term benefits:

1. Preserves Natural Knee Function

The meniscus plays a critical role in shock absorption, joint stability, and load distribution.
Repairing the tear helps maintain natural knee biomechanics.

2. Reduces Risk of Arthritis

Preserving the meniscus protects cartilage and lowers the risk of early-onset osteoarthritis, especially in younger patients.

3. Long-Term Joint Health

Unlike meniscectomy (removal), repair helps prevent long-term joint degeneration and supports better outcomes over time.

Why Preserve the Meniscus of the Knee Joint?

The meniscus is a crucial, C-shaped piece of cartilage that acts as a shock absorber between your thigh bone (femur) and shin bone (tibia). Preserving the meniscus whenever possible is key to maintaining long-term knee health and mobility.

1. Shock Absorption & Load Distribution:

The meniscus distributes weight and absorbs impact during walking, running, and jumping.

2. Maintains Joint Stability:

The meniscus contributes to the stability of the knee, especially during rotational and side-to-side movements.

3. Prevents Early Osteoarthritis:

Loss of the meniscus can lead to direct bone-on-bone contact, increasing the risk of cartilage damage and early-onset arthritis.

4. Preserves Long-Term Knee Function:

Keeping the meniscus intact helps maintain normal knee mechanics, allowing for better mobility and function.

Conclusion

Preserving the meniscus through arthroscopic meniscus repair is a crucial step in maintaining long-term knee health, joint stability, and function. Whenever possible, repairing the meniscus instead of removing it helps protect against future problems like arthritis, joint degeneration, and mobility loss.

Thanks to modern arthroscopic techniques, meniscus repair is a safe, minimally invasive, and effective procedure that allows for faster recovery, less postoperative pain, and a strong return to daily activities or sports.

Whether you’re an athlete or simply want to stay active and pain-free, choosing meniscus repair — when medically appropriate — is an investment in the future of your joint health.
