What is a Knee Instability Test?
Knee instability is a condition that affects the knee joint, leading to feelings of weakness, giving way, or buckling of the knee during movement. Various factors, including ligament injuries, meniscal tears, or other structural issues within the knee, can cause it. Patients with knee instability often experience difficulty in walking, running, or participating in physical activities without fear of their knee giving out.
Medical professionals use the or the Lachman Test to identify knee instability and evaluate its severity. This physical examination is used to assess the stability of the knee joint, particularly to evaluate the integrity of the anterior cruciate ligament (ACL). The ACL is one of the major ligaments in the knee that helps stabilize and control forward movement of the tibia (shin bone) relative to the femur (thigh bone).
During the Knee Instability Test, the examiner evaluates the amount of anterior translation or forward movement of the tibia relative to the femur when the knee is partially flexed (usually around 20-30 degrees of flexion). The test is often performed by orthopedic surgeons, sports medicine physicians, physical therapists, or other healthcare professionals.
How does the Knee Instability Test work?
Using our free template, you can easily conduct the Knee Instability Test or Lachman Test. Follow these steps to perform the exam:
Step One: Download the free worksheet
Access the printable Knee Instability Test template through the link on this page or the Carepatron app, or download it from our resources library.
Step Two: Explain the Knee Instability Test to your patient
Inform your patient that the Knee Instability Test is designed to assess if they have knee instability. Explain the symptoms of knee instability and how the test can help diagnose the condition.
Step Three: Perform the Knee Instability Test
Use the instructions listed on the template to conduct the exam. Ensure your patient is lying comfortably in the supine position (on their back) with their leg bent at approximately 20-30 degrees of flexion. Then, stabilize your patient’s thigh and gently apply a controlled forward force to the lower part of their shinbone.
Step Four: Evaluate the Results
Once the test is complete, analyze the results. Look for any occurrences of knee instability or feelings of giving way during the performed movements, which can indicate the presence and severity of knee instability.
Knee Instability Test Interpretation
The Knee Instability Test is a valuable tool for assessing the presence and severity of knee instability in patients. If your patient experiences knee giving way or feelings of instability during the test, it suggests the presence of knee instability. The test results can also help determine the appropriate course of action, such as conservative treatments or referral to a knee specialist.
Please bear in mind that the Knee Instability Test is just one component of a thorough diagnostic process. When reaching a final diagnosis, consider additional factors like the patient's medical history, results from imaging studies, and findings from physical examinations.
