Renne test

Purpose

Renne's test was developed in 1975 to test for iliotibial band syndrome (ITB).[1][2] This test can be performed instead of or in addition to the Noble Compression Test when the patient complains of lateral knee pain and sometimes crepitus when running.

Clinical Relevance

Iliotibial band friction syndrome, first described by Renne in 1975 is commonly found in middle- and long-distance runners and in those athletes whose sports require repetitive knee flexion. It is also found in skiers, cyclists, weightlifters, and soccer athletes[1]. It is an overuse condition caused by excessive friction between the ITB and the lateral femoral epicondyle which results in either bursitis over the lateral femoral epicondyle and/or inflammation of the ITB and periosteum.

Technique

Procedure: The patient is standing while weight bearing on the involved side. This can be performed with the non-involved side weight bearing or non-weight bearing knee flexed.

  • Palpation: Patient sits or kneels while you palpate the iliotibial band (ITB) on or just above the lateral femoral epicondyle. The patient is instructed to place one hand on the examiner’s shoulder for balance and slowly squat (one legged) to 60-90°flexion and then rise back up. First, palpate the ITB just above the lateral femoral epicondyle,
  • Compression: Then have the patient squat and rise a second time while this time applying firm pressure (Renne 1975, Linenger 1992)[3].

Interpretation:

  • Palpation in is intended to feel for crepitus. Palpatory crepitus, snapping &/or pain at the lateral epicondyle are positive signs of ITB syndrome.
  • Firm pressure is intended to provoke the lateral knee pain and increase crepitus.

Both the Nobel/Rene’s tests are usually the most provocative; expect provocation to be greatest when the knee is about 20-30˚flexed[4].

Common Procedural Errors: Examiner does not instruct patient to place the hand on the examiner's shoulder to maintain balance. Those with balance problems or who are unable to perform a squat on one leg can perform the test with both lower limbs bearing weight - be careful to watch out for compensation where the patient shifts most of their weight to the opposite side.
