The Source of Fluid Deep to the Iliotibial Band: Documentation of a Potential Intra‐Articular Source

Abstract: The lateral synovial recess appears to regularly extend beneath the anterior ITB. Fluid deep to the ITB should precipitate further evaluation of the knee joint when clinically indicated. Although distention of the lateral synovial recess is not always symptomatic, synovial irritation may be a pathoetiologic factor in the production of lateral knee pain syndromes, including ITB syndrome.

“…Fluid measurements were limited as participants maintained a standing position with the knee in 0° extension only. It may have been more beneficial to measure fluid in a different position; however, the decision to measure distal ITB fluid in this manner was based on previous studies showing the highest likelihood of fluid detection in this position [13]. The risk of protocol deviation due to varying scanning techniques and different skill levels among the multiple study investigators may have also played a role in distorted measurements.…”

“…During running or cycling, irritative stresses on the ITB and the underlying tissues caused by anteroposterior movement or mediolateral movement of the ITB over the lateral femoral epicondyle result in this syndrome. 30 The pathology of ITBFS still remains controversial. The earlier hypothesis of ITBFS is that the repetitive friction of ITB over the lateral femoral condyle causes thickening of the ITB, as well as a bursitis in the sub-ITB space.…”

“…31,33 Knee effusion with extension to the LSR deep to the ITB is a regular phenomenon (see Figure 2D). 30 If patients do not have ITBFS symptoms, the effusion in the LSR may only imply that the amount of fluid in the knee joint is significant. If patients have ITBFS symptoms, it is crucial to determine if the source of the fluid is from the knee joint or an isolated accumulation.…”

“…Une rétraction du fascia lata peut être recherchée par le test d'Ober sur un patient en décubitus latéral sur le côté sain, hanche et genou sains à 90° de flexion: le patient a des difficultés à réaliser une adduction de la cuisse (genou à 90°) au-delà de la ligne médiane, avec apparition d'une douleur de la face latérale du genou [21]. L'imagerie n'a pas d'intérêt dans les formes typiques, en dehors de l'échographie dynamique ; en effet celle-ci a permis de démontrerchez des coureurs à pied asymptomatiques -que la bandelette iliotibiale a une mobilité antéropostérieure par rapport au condyle latéral dans l'arc de mobilité 0-45° en charge et en décharge combinée à une réduction de sa largeur [23], associée à un épanchement liquidien sous la bandelette dont la présence varie selon la position (95% en charge et en extension vs 22% à 30° de flexion), en rapport possible avec une extension du récessus latéral synovial [24]: cet épanchement n'est donc pas toujours synonyme d'un SBIT. En pratique, la sensibilité de l'échographie dans le bilan d'un SBIT est faible.…”
