Understanding the McMurrays Test Assessment
To assess for a tear of the **medial or lateral meniscus** of the knee joint.
Watch How It's Done
How do I start?
Patient is supine. The hip and knee are maximally flexed.
What happens?
**Medial Meniscus:** The tibia is held in **external rotation**. The examiner applies a **valgus stress** while slowly extending the knee. **Lateral Meniscus:** The tibia is held in **internal rotation**. The examiner applies a **varus stress** while slowly extending the knee.
In Plain English
What Does a Positive Result Mean?
A palpable or audible **click or thud** felt or heard along the joint line during extension, often accompanied by pain.
Helpful Tip:
The rotating and extending movement traps the torn portion of the meniscus, causing the click.
Safety First
This guide is to help you understand what happens in a clinic. Do not try to diagnose yourself. If you have severe pain, swelling, or cannot put weight on your leg, please visit an urgent care center or your doctor immediately.
Other Knee Tests
Pivot Shift Test
To dynamically assess for **anterolateral rotatory instability** of the knee, which is highly indicative of a **complete ACL tear**.
Posterior Drawer Test of the Knee
To assess the integrity of the **Posterior Cruciate Ligament (PCL)**.
Posterior Sag Sign (Gravity Drawer Test)
To detect a rupture of the **Posterior Cruciate Ligament (PCL)** by observing the effect of gravity.
Slocum Test (Anterolateral Rotatory Instability)
To assess for **anterolateral rotatory instability** and the function of the **Anterolateral Ligament** (a dynamic variant of the Anterior Drawer).
