Execution
- 1Position the patient supine.
- 2Flex the test hip to approximately 90 degrees with the knee flexed.
- 3Adduct the hip across the midline.
- 4Internally rotate the hip to end range or symptom reproduction.
- 5Record pain location, mechanical symptoms, and whether the pain is the patient’s familiar anterior groin pain.
Positive outcome
Anterior groin pain or familiar deep hip pain during flexion, adduction, and internal rotation is positive. Clicking or catching may increase suspicion of intra-articular pathology, but pain location is more important than the click alone. Lateral or posterior pain should be interpreted cautiously.

CommentFADDIR is one of the most sensitive tests for FAI / labral presentations, but specificity is poor and false positives are common in hip pain populations. It is better for ruling out than ruling in when negative in the right context. A positive FADDIR should lead to clustered assessment, imaging correlation, and differential screening rather than a standalone FAI diagnosis.
