What is the meaning of valgus stress?
The valgus stress test or medial stress test, is a test for damage to the medial collateral ligament of the knee. If the knee is seen to open up on the medial side, this is indicative of medial collateral ligament damage and may also indicate capsular or cruciate ligament laxity.
What does a positive valgus test mean?
A positive test occurs when pain or excessive gapping occurs (some gapping is normal at 30 degrees). Be sure to not include rotation of the hip in your application of force. Next the examiner should repeat the test with the knee in neutral (0 degrees of flexion).
What is considered a positive with the valgus stress test?
To perform the moving valgus stress test, the examiner applies and maintains a constant moderate valgus torque to the fully flexed elbow and then quickly extends the elbow. The test is positive if the medial elbow pain is reproduced at the medial collateral ligament and is at maximum between 120 degrees and 70 degrees.
What is valgus stress on the knee?
The valgus stress test, also known as the medial stress test, is used to assess the integrity of the medial collateral ligament (MCL) of the knee. MCL injuries are common in the athletic population and can occur as either isolated injuries, or combined with other structural injuries.
What is valgus injury?
A common triad of injury (particularly in athletes) when a valgus force is applied to the knee involves injury to the MCL, the medial meniscus, and the anterior cruciate ligament. Most patients are able to continue ambulating after an acute injury. Pain and stiffness are localized to the medial knee.
What is a valgus stress on the knee?
Is valgus medial or lateral?
The terms valgus and varus refer to angulation (or bowing) within the shaft of a bone or at a joint in the coronal plane. It is determined by the distal part being more medial or lateral than it should be. Whenever the distal part is more lateral, it is called valgus.
What causes knee valgus?
Knee valgus results from a combination of femoral and tibial motions, which can be influenced by the joints proximal and distal to the knee, including the trunk, hip, and ankle. Lack of femoral control can result in excessive adduction and internal rotation, which can stress the ACL.
What is valgus of the knee?
Valgus knee is a lower leg deformity that exists when the bone at the knee joint is angled out and away from the body’s midline. This causes the inability for a person to touch his or her ankles while the knees touch together.
