What does the term "varus stress" refer to in joint examination?

The term "varus stress" in joint examination specifically refers to a force that moves the joint away from the midline of the body. This type of stress is commonly assessed during physical examination to evaluate the integrity of the ligaments, particularly in the knees or elbows. In a varus stress test, the examiner applies pressure to the lateral side of the joint, which causes it to pivot or bow outward.

This testing is often employed to assess for injuries to the ligaments that stabilize the joint, as excessive varus stress can lead to injuries such as damage to the collateral ligaments. Understanding the mechanics of varus stress is essential for healthcare providers to accurately diagnose and treat joint injuries and conditions.
