Lateral Meniscus Tear: Knee Injury Awareness and First Aid in Canada

A lateral meniscus tear involves damage to the outer cartilage cushion of the knee joint. Each knee has two menisci that help absorb shock and support smooth movement. Tears can occur suddenly from twisting movements or trauma, or gradually due to wear and tear over time.

Meniscus injuries are common in sports, physical work, and everyday activities.

Understanding the Risk

A lateral meniscus tear may occur due to:

• Sudden twisting or pivoting on a bent knee
• Direct impact to the knee
• Squatting or lifting while rotating
• Gradual degeneration with age

These injuries can affect knee stability and function if not properly managed.

Common Signs and Symptoms

Symptoms of a lateral meniscus tear may include:

• Pain or tenderness along the outer joint line of the knee
• Swelling that develops within 24–48 hours
• Pain when bending, squatting, or twisting the knee
• Stiffness or limited knee movement
• A feeling of the knee “catching” or locking

Persistent pain or swelling should not be ignored.

First Aid Awareness: What to Do

First aid does not diagnose a meniscus tear, but early care helps protect the joint and reduce symptoms.

If a meniscus injury is suspected:

• Stop activity immediately
• Avoid putting weight on the injured knee if painful
• Use cold application to help reduce swelling
• Keep the knee supported and elevated when possible

Seek medical assessment if:

• Pain or swelling does not improve
• The knee feels unstable or locks
• Walking becomes difficult
• Symptoms worsen over time
• The injury follows significant trauma

Sudden inability to bear weight or severe swelling should be assessed urgently.

Why This Awareness Matters for Canadians

Knee injuries are common in Canada due to sports participation, winter slips, and physically demanding work. First aid training, including in advanced and standard first aid courses, emphasizes:

• Early recognition of joint injuries
• Preventing further damage through activity modification
• Knowing when professional care is required
