What is a positive meniscus test?
A test is considered positive when a click is felt over the meniscus as the knee is brought from full flexion (completely bent) to 90 degrees.
How do you assess the meniscus?
The current standard used to assess for the presence of meniscal tears is to palpate along the joint line while applying a varus or valgus stress to the knee. It is important to feel for associated crepitation within the joint when performing this and also check if the patient has any pain with this maneuver.
What does a positive medial McMurray test mean?
The test is considered positive for a torn meniscus if the examiner appreciates a palpable or auditory click while rotating and extending the knee.
What does medial joint line tenderness mean?
Tenderness to palpation over the medial joint line often signifies two common etiologies: medial meniscal tear and degenerative joint disease. This point is found by first palpating the inferior pole of the patella with the knee in 90 degrees of flexion and then moving medial along the joint line.
What does Thessalys test test for?
The Thessaly Test was first described in 2005 by Karachalios et al. as a novel clinical examination used to detect meniscal tears in the knee. When performed at 20° of knee flexion it is reported to have a high diagnostic accuracy rate for detecting both lateral and medial meniscal tears.
Is the McMurray test accurate?
Results showed that the McMurray’s test had a sensitivity 34.3% and a specificity of 86.4%. Sensitivity of the test for joint-line tenderness was 62.9% and the specificity 50%. We studied a population that had a longer duration of injury of at least 6 mo.
How do you self diagnose a torn meniscus?
To test for a lateral meniscus tear (on the outer side of the knee), you’ll be asked to turn your toes inward as far as your knees can rotate. You’ll then squat and slowly stand up. A click or pain can indicate a meniscus tear.
How do you perform the Lachman’s test?
This test is done by bending the hip 45 degrees and the knee 90 degrees, then pulling the knee forward with a sudden jerk to test the leg’s range of motion. If it moves 6 mm beyond its normal range of motion, then you may have an ACL tear or injury.
What does a positive Lachman test feel like?
Anterior translation of the tibia associated with a soft or a mushy end-feel indicates a positive test. More than about 2mm of anterior translation compared to the uninvolved knee suggests a torn ACL (“soft end-feel”), as does 10mm of total anterior translation.
How do you test if you have a torn meniscus?
Symptoms
- A popping sensation.
- Swelling or stiffness.
- Pain, especially when twisting or rotating your knee.
- Difficulty straightening your knee fully.
- Feeling as though your knee is locked in place when you try to move it.
- Feeling of your knee giving way.
Can you play sports with meniscus tear?
Some people can still walk or even play sports after their meniscus is torn, but may be limited by any of the previously mentioned symptoms. Sometimes a ‘pop’ or ‘snap’ will be heard when the injury occurs. Common Treatment: Meniscus tears do not usually heal.
How do you test the medial meniscus with the McMurray test?
In order to test the medial meniscus, bring the knee into full flexion and laterally rotate the tibia. The anterior half of the meniscus is not as easily tested with the McMurray Test because the pressure on the meniscus is not as high.
How do you interpret a positive McMurray test?
How to Interpret McMurray Test Positive Finding: A positive test occurs when pain or popping occurs while extending the knee during the McMurray test. Tibial rotation during the McMurray test isolates the medial and lateral meniscus, applying stress to the meniscus with the twisting and extension motion.
How to perform Lachman test for meniscus tear?
Pain or a popping sensation indicates a lateral meniscal tear. To test the medial meniscus, the examiner will place the knee into flexion once again, externally rotate the tibia, and extend the knee while applying a valgus force to the knee. Pain or a popping sensation indicates a medial meniscal tear. Next Article: How to Perform Lachman Test
How accurate is joint line tenderness as a test for meniscus tears?
Eren OT (10) in his study showed that the joint line tenderness as a test for lateral meniscus tears is accurate (96%), sensitive (89%), and specific (97%). However, for medial meniscus tears, rates are lower.
