“…Arrow points to the expected location of the POL, which is torn and replaced with edematous tissue. The POL is posterior to the sMCL on the axial image (it has a posteriorly directed course as it spans from the region of the gastrocnemius tubercle to the tibia) [1]. c Coronal T2‐weighted image with fat saturation shows a complete tear of the POL with proximal retraction.…”

“…Arthroscopy is also a useful adjunct and shows pathology that might correlate with medial-sided knee injury. Ambrose et al [1] demonstrated that arthroscopic evaluation of the relationship between the medial femoral condyle, medial meniscus, and medial tibial plateau is useful for diagnosing an MCL lesion. Miller et al [20] noted a 45% incidence of bone bruising with MCL injuries-the lateral femoral condyle was most frequently involved followed by the lateral tibial plateau.…”

Injury patterns to the posteromedial corner of the knee have not been previously studied in the context of multiligament knee injuries. We performed a retrospective magnetic resonance imaging and clinical review of a consecutive series of 27 dislocatable knees presenting to a single level-one trauma center from 2005 to 2008. Post-injury magnetic resonance imaging studies were reviewed by two fellowship-trained musculoskeletal radiologists to assess injury patterns to the posteromedial corner. In our series, injury to at least one structure within the posteromedial corner was observed in 81% (22/27) of cases while injury to the superficial medial collateral ligament alone was seen in 63% (17/27) of cases. Furthermore, injuries to the posterior horn of the medial meniscus were associated with a tear of the meniscotibial ligaments in all cases and with a tear of the posterior oblique ligament in 67% of cases. All patients with grade III laxity (>10 mm medial opening) under an examination under anesthesia had a complete tear of the posterior oblique ligament and meniscotibial ligament in addition to a medial collateral ligament injury. Injury to the semimembranosus attachment alone was not associated with clinically significant laxity under an examination under anesthesia. Our findings demonstrate that injuries to the posteromedial corner are common in the setting of traumatic knee dislocations. Interestingly, high-grade medial instability during an examination under anesthesia and injury to the posterior horn of the medial meniscus may be important indicators for further posteromedial corner injury.

“…The dMCL is reported as the primary restraint for anteromedial rotational laxity (AMRL) at all ranges of knee flexion [9,10,23] and tolerates forces up to 100.5 ± 10.3 N [8,54]. Due to its close association with the joint and fibrous attachments to the medial meniscus (MM), concurrent dMCL/MM pathologies often occur [5,47,50]. Moreover, there is also load sharing between the dMCL/sMCL and dMCL/ACL complexes; injury to one component confers additional stabilising responsibilities to the other [7,19,45,58].…”
