Flexion test in the coronal plane deformities of knee

Area of Science:

• Orthopaedic surgery
• Clinical biomechanics

Background:

• Limited literature exists on bedside assessment of knee coronal plane deformities.
• Accurate clinical evaluation is crucial for effective orthopaedic treatment.

Purpose of the Study:

• To elucidate the 'knee flexion test' for practical clinical application.
• To enhance the diagnostic skills of orthopaedic clinicians and students.

Main Methods:

• Detailed description of the 'knee flexion test' principle.
• Explanation of prerequisites, potential pitfalls, and modifications.
• Inclusion of a case study with genu valgum deformity.

Main Results:

• The 'knee flexion test' provides a reliable method for evaluating coronal plane alignment.
• The described modifications enhance the test's accuracy and applicability.
• Case illustration demonstrates successful identification of tibial-origin genu valgum.

Conclusions:

• The 'knee flexion test' is a valuable addition to the orthopaedic bedside examination.
• Routine use of this test can improve the diagnosis of knee coronal plane deformities.
