Medial Compression Test |
Examination type |
medial menisci |
Patient & Body Segment Positioning |
The patient is instructed to lie in a supine
position. First, the patient will be tested in hip flexion at 90
degrees and knee flexion at 90 degrees, internally and
externally rotated. Then the patient will be further tested in
hip flexion at about 45 degrees and full knee extension,
internally and externally rotated |
Examiner Position |
The examiner will be standing on the side of the
injured knee. The hand closes to the body will grasp the knee at
the medial joint line, and the hand closes to the ankle will
grasp the foot. From this position the examiner should be able
to manipulate the movement of the joint. |
Tissues
Being Tested |
medial meniscus |
Performing the Test |
The examiner will actively apply pressure to the
knee joint while internally and externally rotating the knee in
flexion and extension. |
Positive Test |
While performing the test you will feel a
click with the hand on the knee. The patient will also feel pain
in the medial aspect of the knee. |
Interpretation |
If the medial compression test is positive the
patient has a medial meniscus tear. |
Common errors in
performing exam |
Wrong positioning or bad hand placement by the
examiner. Examiner may not go through the full range of
motion, which may result in missing a tear in either extreme
flexion or extreme extension. |
Factors possibly
resulting in misinterpretation |
While performing the test the examiner is putting
a compression force on the joint so there is always a
possibility of other injured structures giving the examiner a
false positive test, make sure to ask patient to be specific
about pain. |
