“…The underestimation and misinterpretation of reporting injuries in these specific areas can result in a poor patient outcome. For example, chronic posterolateral instability for untreated PLC injuries 4,5 and valgus instability for PMC deficiencies 6 can cause reconstruction of the central supporting structures to fail long term. Therefore, a full appreciation of PMC and PLC structures is of primary importance in the MRI evaluation of the knee to generate a relevant, pertinent, and exhaustive report that will guide the clinical or surgical management of these patients and improve patient outcome.…”

“…Clinically, the stabilizing role of the lateral gastrocnemius is recognized in PLC reconstruction, including advancement procedures. 4,69 Injuries to the gastrocnemius muscle usually involve the distal myotendinous junction of the medial gastrocnemius (tennis leg). 70 Although primary injuries of the lateral gastrocnemius are rare, the lateral gastrocnemius should be evaluated carefully in cases of posterolateral corner injury because of the secondary stabilizing role of this structure.…”

“…Moreover, PLC and PMC injuries uncommonly occur in an isolated fashion, more often associated with concomitant injuries that may dominate the clinical picture. Untreated PLC injuries can lead to chronic posterolateral instability 4,5 and PMC deficiencies may cause persistent valgus instability 6 ; both conditions lead to poor outcome of anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) reconstruction. It is therefore imperative, in a postinjury or preoperative setting, to provide the referring physician with an accurate description (when possible) of the PLC and PMC structures.…”

“…Others believe that the primary static stabilizer is the fibular origin of the popliteal muscle [65,66]. A hyperextension injury may result in external rotation and posterior subluxation of the lateral tibia with respect to the femur, an entity called posterolateral rotatory instability [67]. These injuries are not uncommon, and are difficult to detect clinically.…”

Magnetic resonance imaging has had a dramatic effect on the means by which we diagnose ligament injuries. Tears resulting from either acute trauma or overuse can be detected noninvasively, directing appropriate therapy be it conservative or surgical. For the elite athlete, earlier diagnosis leads to earlier intervention, or alternatively, a normal MRI examination can result in an earlier return to play. While MRI is accepted for the diagnosis of certain injuries such as complete tears of the cruciate ligaments of the knee, other injuries, such as partial cruciate ligament tears or tears of the intercarpal ligaments of the wrist, remain controversial.

“…Most lesions of this type are included within the context of complex knee injuries, specifically in association with anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) injuries. [2][3][4][5] Study of the posterolateral complex is growing in importance because of the complex instability generated by these injuries, as well as the higher failure rates in reconstructions of the ACL and PCL in the presence of unidentified PLC lesions. 3,[6][7][8][9][10][11] Clinical evaluation to identify PLC injury begins during the examination.…”

Injury to the posterolateral corner (PLC) is difficult to diagnose; most lesions of this type are included within the context of complex knee injuries. Study of the posterolateral complex is growing in importance because of the complex instability generated by these injuries. Although various physical examination tests are described for the diagnosis of PLC lesions, in 72% of cases these lesions are not identified at their initial presentation, which shows the difficulty in both performing these tests and interpreting the results. The maneuver described in this report is performed by executing external rotation of the leg. With the thumb of the proximally positioned hand, the examiner evaluates the positioning of the lateral tibial plateau in relation to the femoral condyle. With this maneuver, in lesions of the PLC and particularly lesions of its external rotationerestricting structures, we observe external rotation of the tibia and posterior subluxation of the lateral tibial plateau that cause the anterior edge of the tibial plateau to be posteriorized in relation to the anterior edge of the lateral femoral condyle. The idea behind this maneuver is not to eliminate the use of other tests but, rather, to add it to a diagnostic arsenal that still has interpretation flaws.
