Bounce Home Test for Meniscus to Knee Joint

The bounce home test is a physical examination used to assess the integrity of the knee joint, particularly for detecting meniscal injuries or joint effusion. The test involves passively extending the knee from a flexed position to observe if it “bounces” or lacks a smooth, complete extension, indicating possible intra-articular pathology.

• This test is used to better understand meniscus injury.
• It is an orthopedic test to check the injury of the meniscus of to knee joint.
• It is a test to decrease knee extension.

What is the Purpose of the bounce home test?

• This test is used to check to integrity of to meniscus.
• It is also used to check for meniscus injury means a torn meniscus.

How do you perform to bounce home test?

• Starting position for testing is supine.
• Into supine position heel of to patient’s foot is hold in cupped manner in to examiner’s hand.
• Patient is knee is fully flexed & then the knee is passively allowed to extended.
• Knee is able to fully extend but with to sharp end feel.

First modification :

• It is described by Oni.
• Named of modification is a knee-jerk test.
• In this test, do the knee extension forcefully.
• So that pain occurs in to area of tissue injury.

Second modification:

• It is described by Shybut & McGinty.
• In this modification, do the simple force of knee hyperextension.
• The test is positive when to feels the blocking of forced hyperextension.

Evidence bounce home test?

• Original bounce home test = There are no studies for investigating to sensitivity, specificity & diagnostic accuracy.

• Bounce home test, which is described by Shybut & McGinty:
• Sensitivity of this modification = 47%
• Specificity of this modification = 67%
• Diagnostic accuracy of this modification = 51%.

• Knee-jerk test modification, which is described by Oni = not to investigate.
