To perform the varus stress test at 30° of knee flexion, the leg is placed over the examining table with the knee flexed at between 20°-30°. One’s fingers are then placed over the joint line while the distal femur is stabilized. A varus stress is then applied to the knee while one is holding the foot and ankle. One’s fingers can then assess for the amount of gapping. Just like the ... Patient Position. Supine (or seated) Procedure Steps. Supine testing . Drop the leg off the table and flex the knee to 30°. Put fingers over the lateral joint line.; Grab the ankle/foot and apply a varus stress to the knee (using the medial knee against the outside of the table as a fulcrum and pushing the ankle lateral to medial).; Compare to the opposite, unaffected side. Purpose: The Varus Stress Test is used to assess the integrity of the LCL or lateral collateral ligament of the knee.This is a key test to perform when assessing for posterolateral instability of the knee. How to Perform Varus Stress Test. Position of Patient: The patient should be relaxed in the supine position. Performance: The examiner will support the knee and lower leg at the ankle ... Varus and valgus laxity of the knee with the TKA implant was measured a few days before the contralateral TKA without anesthesia and again immediately after the contralateral TKA under spinal anesthesia. Results: The laxity was significantly increased from 3.0° to 3.6° (p = 0.005) and from 4.7° to 5.7° (p = 0.007) in medial and lateral side, respectively, when the stress tests were ... Importance of Test: The medial collateral ligament is important for resisting valgus force at the knee due to its attachments along the femur, meniscus, and tibia. The MCL also plays a major role in restraining tibial external rotation. Surgical severing of the superficial portion of the MCL was shown to increase tibial external rotation at 90 degrees by about 3 times (Ellenbecker, 2000 ... Valgus and Varus Stress Test. Name. Purpose. Description. Sensitivity, Specificity. Validity, Reliability. Likelihood Ratio +/-Valgus Stress Test . An assessment for one-plane medial instability (gapping of the tibia away from the femur on the medial side). [1] The therapist applies a valgus stress at the knee while the ankle is stabilized in slight lateral rotation either with the hand or ... 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. With the fibular nerve also located around the fibular head, any injury with a mechanism of a varus force to the knee could potentially stress the fibular nerve as well. Other tissues at risk with these injuries include the PCL and ... The valgus test 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. If the knee is seen to open up on the medial side, this is indicative of medial ligament and / or cruciate ligament damage. Varus Stress Test of the Knee: PURPOSE: Testing for the integrity of the structures that prevent lateral instability at the knee (lateral collateral ligament, joint capsule, cruciate ligaments). VIDEO DEMO, PROCEDURE, Positive Sign: Presence of pain and hypermobility at the lateral aspect of the knee... Varus and valgus stress tests of the knee are used to determine the presence of MCL or LCL pathology. To perform this test, have the patient lying supine with the hip flexed to 45 degrees, then take the patient’s leg and secure it between your body and elbow. Apply varus and valgus stress at the joint and assess for the degree of laxity at ...
