Meniscus Tear

The meniscus is a crescent-shaped cartilage structure located within the knee joint. These structures protect the articular surfaces between the femur (thigh bone) and tibia (shin bone), act as shock absorbers, and help facilitate smooth joint movement. The menisci are divided into two main sections: medial (inner) and lateral (outer).

What Is a Meniscus Tear?

A meniscus tear is a tear in the meniscal cartilage of the knee joint. This condition typically occurs due to twisting of the knee, sudden changes in direction, or excessive stress. Tears can vary in severity, ranging from small, minor tears to large tears that significantly compromise joint stability.

Symptoms of a Meniscus Tear:

Pain in the knee, especially during weight-bearing or movement
Swelling and inflammation
Locking of the knee, restricted range of motion, or a catching sensation
Tenderness or localized pain, particularly on the inner (medial) side of the knee

Non-Surgical (Conservative) Treatment

Indications:

Small tears
Mild pain
Older adults

Management Includes:

Rest, ice, and compression
Analgesic medications
Physical therapy and exercises
Use of a knee brace or splint

Goal:

To reduce pain and protect the meniscus

Recovery Time:

Healing may occur within 6–12 weeks

Arthroscopic Treatment of Meniscus Tears

Meniscus tears can often be managed with conservative treatments; however, surgical intervention may be required in certain cases. Arthroscopic surgery is a minimally invasive technique frequently used for the treatment of meniscus tears.

Arthroscopic Meniscus Surgery

Meniscus Tear Repair (Suturing):
If the tear is located in the vascularized region of the meniscus, surgeons may opt to repair it with sutures. This allows the meniscus to heal naturally.
Partial Meniscectomy (Removal of Meniscal Fragments):
If the meniscus tear is too large to be repaired or carries a risk of further damage, the damaged portions are typically removed. The remaining healthy meniscus is preserved to maintain knee function.

Advantages of Arthroscopic Surgery

Small Incisions: Arthroscopic surgery is much less invasive than traditional open surgery, requiring only a few small incisions.
Faster Recovery: With less tissue damage, patients can recover more quickly and return to normal activities sooner.
Reduced Pain: Patients generally experience less pain and discomfort compared to traditional open surgery.
Lower Risk of Infection: The smaller incisions reduce the risk of postoperative infection.
