Anterior approach for knee arthrography

Objective. To develop a new method of magnetic resonance arthrography (MRA) of the knee using an anterior approach analogous to the portals used for k nee arthroscopy. Design. An anterior approach to the knee joint was devised mimicking anteri or portals used for knee arthroscopy. Seven patients scheduled for routine knee MRA were placed in a decubitus position and under fluoroscopic guidanc e a needle was advanced from a position adjacent to the patellar tendon int o the knee joint. After confirmation of the needle tip location, a dilute g adolinium solution was injected. Results and conclusion. All the arthrograms were technically successful. Th e anterior approach to knee MRA has greater technical ease than the traditi onal approach with little patient discomfort.
