What is the figure 4 test for knee pain?

The figure 4 test, also known as the Patrick or FABER test, is a common clinical assessment used to evaluate hip and knee pain. This test helps identify conditions affecting the hip joint, sacroiliac joint, and surrounding muscles and ligaments.

Test Procedure

During the test, the patient lies on their back with one leg extended and the other leg bent, placing the ankle on the opposite thigh to form a figure 4 shape. The examiner applies gentle pressure on the bent knee while stabilizing the opposite hip, stretching the hip joint and nearby structures to observe the patient’s reaction.

Indications of Pain

Pain during the test can indicate hip joint dysfunction, sacroiliac joint issues, or muscle strain. The test is useful for distinguishing between hip-related pain and pain from other areas, like the lumbar spine. It also provides insight into hip joint flexibility and range of motion.

Clinical Significance

Overall, the figure 4 test helps healthcare professionals diagnose hip and knee pain, guiding further investigation and treatment plans for better patient outcomes.
