Lecturer & Meniscus Tear Symptoms in Egypt | Knee Pain & Locking | Dr. Mohamed Labib

What is the Meniscus?

The meniscus is a pair of C-shaped fibrocartilage discs (medial and lateral) inside your knee joint. They act as the primary shock absorbers, evenly spreading load across the joint surface, and playing a crucial role in rotational stability. When torn, they can cause severe mechanical symptoms and, if untreated, lead to accelerated knee arthritis.

Key Symptoms of a Meniscus Tear

Joint Line Pain: A localized ache along the inner (medial) or outer (lateral) side of the knee. This often worsens when pressing on the exact area of the tear.
Swelling: Gradual swelling that develops over 24-48 hours after injury (unlike ACL tears which swell rapidly). In chronic tears, the knee can feel persistently puffy.
Clicking or Catching: A mechanical click or sensation of something "catching" inside the knee during movement. This is torn meniscal tissue catching on the joint surfaces.
Locking: The knee suddenly "locks" — it cannot be fully straightened. This is a hallmark of a "bucket-handle" tear where a large fragment has flipped and is blocking joint movement. This is a surgical emergency.
Pain on Squatting: Discomfort during deep squats or kneeling, as these positions maximally compress the meniscus.
Stiffness After Rest ("Gelling"): The knee feels stiff and painful when you first get up from a chair or bed, then eases with movement.

Acute vs. Degenerative Meniscus Tears

Acute Traumatic Tear

• Sudden twist or squat during sports
• Usually younger patients under 45
• Often occurs with ACL injury
• Best candidates for surgical repair (suturing)

Degenerative Tear

• No specific injury, gradual onset
• Associated with knee arthritis
• Usually patients over 45
• Treatment depends on arthritis grade

Diagnosing a Meniscus Tear

Dr. Labib uses a combination of clinical tests (the McMurray Test, Thessaly Test) and high-resolution 3T MRI to confirm the diagnosis and characterize the tear pattern. This determines whether repair or trimming is the appropriate surgical strategy.

Next Steps

If you recognize these symptoms, schedule an appointment at JointCure Clinic for an expert assessment. Early diagnosis prevents a small meniscus tear from becoming a large, complex one requiring more extensive surgery. See our Meniscus Repair Procedure page for full treatment details.

Frequently Asked Questions

Can a torn meniscus heal on its own?

Small tears in the outer 'red zone' (good blood supply) may partially heal. However, larger tears, bucket-handle tears, and tears in the inner 'white zone' require arthroscopic intervention.

Is meniscus tear pain constant?

No. Many patients have intermittent pain that comes and goes. It often gets worse with twisting, squatting, or climbing stairs, then settles with rest.

How urgent is meniscus surgery?

Acute 'bucket handle' tears that lock the knee are a semi-emergency. Other tears can be scheduled within 2-4 weeks without risk of significant additional damage.
