Summary.

Patellofemoral joint forces and pressures were measured in a cadaver model during intramedullary nailing of the tibia. A significant increase in contact pressures was found at the lateral facet of the patellofemoral articulation using the medial paratendinous approach (P = 0.01) and at the medial facet when using the trans-patellar tendon approach (P = 0.001) to the proximal tibia. Increased contact pressures at the patellofemoral joint may result in chondral injury, which in turn may cause anterior knee pain, a common complication of tibial nailing.

Résumé.

Les auteurs ont mesuré les forces et les pressions de l’articulation fémoro-patellaire sur un modèle cadavérique au cours de l’enclouage intra-médullaire du tibia. Une augmentation notable de la pression au niveau de la facette latérale de la fémoro-patellaire a été mesurée lors de l’utilisation d’un abord paratendineux interne tandis qu’une augmentation de la pression au niveau de la facette médiane était notée lors de l’abord trans-tendineux de l’extrêmité supérieure du tibia (P = 0.01). Ces augmentations de pression au sein de l’articulation fémoro-patellaire peuvent aboutir à une lésion cartilagineuse pouvant provoquer des douleurs antérieures du genou, complication fréquente de l’enclouage tibial.
