Varus Stress Tests

What is a Varus Stress Test?

The Varus Stress Test is a crucial component of orthopedic examinations used to evaluate the integrity of the lateral collateral ligament (LCL) in the knee and elbow. By applying a varus force to the joint, this test assesses ligament injuries, varus instability, and lateral joint line gapping, which are often associated with conditions like knee instability, excessive gapping, or a complete posterolateral corner injury. It is particularly useful in cases involving sports medicine, physical examinations, and preoperative evaluations.

Performed with the patient's knee, either flexed or extended, the test may help detect damage to structures such as the fibular collateral ligament, popliteus tendon, and popliteofibular ligament. Varus gapping and lateral compartment gapping are key indicators of injury, often accompanied by instability or pain on the lateral side of the knee. For elbow assessments, it helps assess the integrity of the lateral collateral ligament of the elbow. This test is commonly used to diagnose ligament injuries, such as sprains or tears, which can result from trauma or repetitive stress. By applying a varus force to the elbow while it's slightly flexed, the test evaluates the stability of the joint.

The Varus Stress Test is frequently used alongside the Valgus Stress Test to provide a comprehensive evaluation of lateral and medial collateral ligament structures. Stress radiographs or arthroscopy may complement the physical examination for increased diagnostic accuracy.

How does our Varus Stress Test template work?

The Varus Stress Test plays a vital role in identifying ligament damage, monitoring rehabilitation progress, and planning treatment strategies for athletes and patients. Here's how you can incorporate this template into your practice:

Step 1: Get the Varus Stress Test template

Get a copy of the template by clicking the "Use Template" button to open a fillable version in the Carepatron app. You can also click "Download" for a ready-to-print version that you can fill out digitally or by hand. In this guide, we've also provided a sample for your reference.

Step 2: Explain how the test works to your patient

Take a moment to explain the purpose and procedure of the test to your patient, ensuring they understand what to expect during the examination. Before beginning, confirm all necessary patient information is accurately recorded.

Step 3: Perform the test

The template outlines both step-by-step procedures for either elbow or knee Varus Stress Test. Here's an overview of how each test is performed:

• Knee: The patient lies in a supine position, with the knee flexed to 30°. One hand is used to stabilize the femur, while the other applies slight lateral rotation to the lower leg. Passive adduction is then performed at the knee joint to stress the lateral collateral ligament.
• Elbow: Instruct the patient to stand and position the elbow in slight flexion while palpating the humeroulnar joint line. Apply a varus force to the elbow. The test is usually done with the elbow flexed between 5 and 30 degrees, but it can be repeated at various angles.

Step 4: Document results and additional information

Our template provides a dedicated section to clearly document the results as either positive or negative, allowing for easy categorization. Additionally, there is space to include any relevant observations or supplementary details that may assist in interpreting the results, such as patient response, test conditions, or any other findings. This ensures comprehensive and accurate record-keeping for future reference.

When would you use this form?

The Varus Stress Test is a fundamental diagnostic tool that finds applications in diverse medical scenarios. Moreover, it forms an essential part of the comprehensive evaluation process of the musculoskeletal system. Five scenarios when it's appropriate to use this resource:

Suspected ligament injury

If acute trauma has occurred to the knee or elbow, the Varus Stress Test aids in evaluating potential ligament damage quickly. It helps determine the severity of the injury and guides immediate treatment or further diagnostic steps.

Chronic pain assessment

For patients experiencing chronic joint pain or instability, the test helps pinpoint whether ligament issues are contributing to their symptoms. It provides valuable insights for creating a targeted treatment plan.

Preoperative evaluation

The Varus Stress Test is crucial for assessing ligament conditions before surgery. It offers detailed information to guide the surgical approach, and surgeons rely on these findings to plan for optimal joint stability post-operation.

Rehabilitation monitoring

During recovery, therapists use the test to measure progress in ligament healing and joint stability. It helps adjust rehabilitation programs to meet the patient’s evolving needs.

Athlete screening

The test is a valuable tool for identifying ligament weaknesses in athletes, potentially preventing injuries through early detection. This proactive approach supports the design of strengthening or preventive measures to enhance performance and safety.
