Article Synopsis
- The study investigates the increasing cases of Schenck knee dislocation type I injuries in the context of multiligament knee injuries, aiming to understand variations in classification within the existing literature.
- A systematic review included 50 studies with a total of 3460 reported KD I injuries, highlighting a low prevalence of tibiofemoral KD confirmation at just 0.3%.
- Findings suggest that unicruciate KD injuries have a significantly lower risk of associated vascular and neurologic injuries compared to bicruciate injuries, indicating important differences in injury management.
Article Synopsis
- The study investigates the impact of resident participation on 30-day outcomes following orthopedic shoulder surgeries, using data from the American College of Surgeons National Surgical Quality Improvement Program.
- The analysis included 5,648 patients, comparing outcomes for those who had surgery with attending surgeons alone versus those with both attendings and residents.
- Findings indicate that resident involvement does not increase the risk of complications, though a higher risk for bleeding transfusions was noted when residents were involved.
After emergent assessment of potentially limb-threatening injuries in knee dislocation or multi-ligament knee injury patients, magnetic resonance imaging is necessary to visualize ligamentous structures and plan for soft tissue repair. However, the application of a knee-spanning external fixator may introduce artifact and reduce overall image quality, which can limit the evaluation of soft tissue injury. As a result, the utility of MRI in the context of a knee-spanning external fixator has been called into question.

The purpose of our study was to poll practicing musculoskeletal radiologists on their personal experiences regarding the use of knee-spanning external fixators in MRI in an effort to consolidate practice trends for the radiologists' benefit.
Methods: A 27-item survey was created to address the institutional use, safety, adverse events, quality, and perspectives of the radiologist related to MRI of an externally fixated knee.
» Universal safety guidelines for the use of a knee-spanning external fixator in magnetic resonance imaging (MRI) are unlikely to be established considering the high variability in device construct configurations.» Per the US Food and Drug Administration, manufacturers are to provide parameters for safe MRI scanning for "MR Conditional" devices; however, such labeling may be limited in detail. Physicians should reference manufacturer labels as a starting point while making an educated clinical decision.
