M. De Maeseneer et al., Posterolateral supporting structures of the knee: findings on anatomic dissection, anatomic slices and MR images, EUR RADIOL, 11(11), 2001, pp. 2170-2177
In this article we study the ligaments and tendons of the posterolateral co
rner of the knee by anatomic dissection, MR-anatomic correlation, and MR im
aging. The posterolateral aspect of two fresh cadaveric knee specimens was
dissected. The MR-anatomic correlation was performed in three other specime
ns. The MR images of 122 patients were reviewed and assessed for the visual
ization of different posterolateral structures. Anatomic dissection and MR-
anatomic correlation demonstrated the lateral collateral, fabellofibular, a
nd arcuate ligaments, as well as the biceps and popliteus tendons. On MR im
ages of patients the lateral collateral ligament was depicted in all cases.
The fabellofibular, arcuate, and popliteofibular ligaments were visualized
in 33, 25, and 38% of patients, respectively. Magnetic resonance imaging a
llows a detailed appreciation of the posterolateral corner of the knee.
