Purpose. 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 the valgus maneuver?
It involves placing the leg into extension, with one hand placed as a pivot on the knee. With the other hand placed upon the foot applying an abducting force, an attempt is then made to force the leg at the knee into valgus.
What does a positive varus stress test mean?
A positive varus stress test at 0° of knee flexion is usually indicative of a severe combined posterolateral corner and cruciate ligament injury.
What is valgus stress test elbow?
The elbow valgus stress test is used to assess the integrity of the medial collateral ligament, also known as the ulnar collateral ligament.
What does a positive valgus test on the elbow mean?
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 ligament is tested by performing the varus stress test?
Diagnostic Accuracy: Sensitivity: . 25 (“Evaluation of knee instability in acute ligamentous injuries”). Importance of Test: The lateral collateral ligament is important for resisting varus force at the knee due to its attachments along the femur and fibular head.
What is the difference between valgus and varus?
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. Whenever the distal part is more medial, it is called varus.
What puts stress on MCL?
With a lax MCL, the ACL becomes increasingly stressed with valgus forces, especially at 45 degrees of flexion (Ellenbecker, 2000). Remember the MCL is the primary valgus restraint in the flexed knee; without it, the ACL is prone to injury.
What is valgus angulation?
Terminology. Valgus is a term for outward angulation of the distal segment of a bone or joint. The opposite condition is called varus, which is a medial deviation of the distal bone. The terms varus and valgus always refer to the direction that the distal segment of the joint points.
What does a positive anterior drawer test indicate?
If the tibia, or shinbone, has more movement, or if the ligament is loose compared with the other knee, the anterior drawer test is considered to be positive. Your physical therapist might suggest that you see your doctor for imaging like a magnetic resonance imaging (MRI).
How can you tell if you tore a ligament in your knee?
What Does a Knee Ligament Injury Feel Like?
Pain, often sudden and severe.A loud pop or snap during the injury.Swelling within the first 24 hours after the injury.A feeling of looseness in the joint.Inability to put weight on the joint without pain, or any weight at all.
