Evaluation of the Reliability of the Dial Test for Posterolateral Rotatory Instability: A Cadaveric Study Using an Isotonic Rotation Machine

Can Wedge Osteotomy Correct Depression of the Lateral Tibial Plateau Mimicking Posterolateral Rotatory Knee Instability?

“…Injuries of this structure may occur in isolation or more commonly as part of a combined ligament injury causing posterolateral rotatory knee instability [6,7,9]. Numerous physical examination techniques like the reverse Lachman test [10], dial test [2,11,12], or Hughston [10] test have been described to detect this condition. Although these maneuvers have been difficult to measure and are based on examiner experience, this clinical entity has been well established in the literature.…”

Functional Movement Analysis in the Differential Diagnosis of a Patient with a Posterolateral Corner Knee Injury

“…This is indicative of a PLC injury without PCL involvement. 15,16 Also noted was increased laxity but solid end-feel with Anterior Drawer and Lachman's on the left. [17][18][19] Pivot-shift, McMurray's, Apley's Compression, Thessaly's and Valgus Stress Testing were negative.…”

Current Concepts in the Recognition and Treatment of Posterolateral Corner Injuries of the Knee

“…An increase of greater than or equal to 15°, as compared to the contralateral side, is considered positive. 1 A Dial test that is positive at 30° of knee flexion but normal at 90° of knee flexion is indicative of a potential injury to the PLC, or more specifically, the popliteus complex. 1 A positive test at both 30° and 90° of knee flexion indicates both a PCL and PLC injury.…”
