Understanding the Beighton Score Assessment
To quantify **generalized joint hypermobility** (laxity) across the body, which can predispose the knee to instability.
Watch How It's Done
How do I start?
Patient is standing.
What happens?
For the **knee component**: The patient is asked to **hyperextend the knee**. The examiner measures the degree of hyperextension.
In Plain English
What Does a Positive Result Mean?
A single point is scored for the knee if it can hyperextend **more than 10°**. A total score of 4/9 or more indicates general hypermobility.
Helpful Tip:
The test is used as a screening tool for underlying ligamentous laxity.
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).
