Knee Arthroscopic Meniscus Repair: Procedure and Recovery

Knee Arthroscopic Meniscus Repair: Procedure and Recovery

Arthroscopic knee meniscus repair is a modern treatment technique that involves minimally invasive surgery to repair torn meniscus tissue.

The health of the knee joint is fundamental to mobility for active individuals and athletes. However, sudden twisting movements or trauma can cause damage to the meniscus tissue. Knee arthroscopic meniscus repair is a contemporary surgical technique that aims to preserve the natural structure of the knee using minimally invasive methods. Unlike traditional open surgery, this approach minimizes damage to surrounding tissues, allowing patients to resume daily activities sooner.

Untreated meniscus tears may lead to persistent pain, locking of the knee, and long-term degenerative changes such as osteoarthritis. Early diagnosis and appropriate surgical treatment are therefore crucial. This article will explore the details of arthroscopic repair, appropriate patient selection, and key considerations during the recovery process, supported by scientific data.

What Is Knee Arthroscopic Meniscus Repair?

Knee arthroscopic meniscus repair involves stitching torn parts of the C-shaped cartilage structure inside the knee through small incisions without opening the joint widely. High-resolution camera equipment called an arthroscope allows the surgeon to visualize the inside of the joint clearly and perform precise repairs.

The primary goal of this procedure is to preserve as much meniscus tissue as possible. Repairing the meniscus instead of removing it (meniscectomy) maintains the knee's load-bearing capacity and reduces the risk of joint degeneration over time.

Meniscus Tears and Treatment Options

Meniscus tears may occur following traumatic injuries, especially in younger individuals, or develop degeneratively with age due to tissue weakening. Factors such as tear location, shape, and size guide the treatment plan. Tears located in the outer, well-vascularized part of the meniscus (red zone) have a higher potential for healing and are ideal for repair.

Treatment options include non-surgical methods (physical therapy, injections) and surgical interventions. For more detailed information, please visit meniscus tears and treatment methods. Meniscus injuries often coexist with ligament injuries; in these cases, anterior cruciate ligament injuries and treatment should be evaluated together.

How Is Arthroscopic Meniscus Surgery Performed?

The question of how arthroscopic meniscus surgery is performed is common among patients. The operation is typically done under general or spinal anesthesia. The surgeon makes two or three small incisions (portals) about 0.5 cm each on the front of the knee. A camera (arthroscope) is inserted through one portal while surgical instruments are used through others.

The surgical procedure follows these steps:

1. Visualization: The joint structures are carefully examined with the camera to confirm the suitability of the tear for repair.

2. Preparation: Torn edges are cleaned to create a fresh surface that facilitates healing.

3. Repair: Specialized stitches or meniscus repair devices are used to secure the torn tissue together.

Advantages of Closed Meniscus Surgery

The benefits of closed meniscus surgery compared to open surgery are significant regarding patient comfort and clinical outcomes. The minimally invasive approach limits tissue damage.

Key advantages include:

• Reduced Pain: Smaller incisions generally result in less postoperative pain.
• Lower Infection Risk: Minimal exposure of the joint to the external environment.
• Faster Recovery: No cutting of muscles or tendons permits earlier initiation of rehabilitation.
• Improved Cosmetic Outcome: Tiny scars instead of large surgical marks.

Postoperative Recovery and Rehabilitation

The recovery phase after successful surgery plays a decisive role in the long-term outcome. Healing time varies based on tear size and repair type, but patients are usually discharged on the day of surgery or the following day. Crutches and knee braces may be needed during the initial weeks.

Rehabilitation aims to restore joint mobility and strengthen muscles. The meniscus surgery rehabilitation process should be tailored to each patient. In particular, knee muscle strengthening exercises are critical to maintaining knee stability.

For athletes, timing the return to sport requires caution as premature activity may cause re-injury. Consult expert opinions on correct exercises after meniscus surgery and return to sport timing.

Risks, Complications, and Precautions

As with all surgeries, knee arthroscopic meniscus repair carries some risks. Though rare, complications such as infection, bleeding (hemarthrosis), nerve injury, or anesthesia-related issues can occur. Additionally, there is a risk that the repaired meniscus does not heal properly or re-tears.

Patients should monitor for the following postoperative signs:

• Increasing pain or swelling
• Redness or discharge at incision sites
• High fever
• Calf pain or tenderness (possible vascular blockage)

If any of these symptoms appear, prompt consultation with a physician is essential. Knee arthroscopic meniscus repair is an effective technique for preserving knee health in suitable cases but depends on strict patient selection, meticulous surgery, and disciplined rehabilitation.
