An anatomical three-dimensional study of the posteromedial corner of the knee.

PURPOSE

For many years, the anatomy of the medial knee corner has been reported. However, it is not exactly clear how all these structures function together. The purpose of this study is to identify and try to understand the relationship between the posteromedial corners of the knee using three-dimensional visualization techniques.

MATERIALS AND METHODS

This study comprises of 10 knees from adult corpses. Images were acquired from the dissection of different layers of the posteromedial compartment of the knee using a camera Nikon D40 and AF-S Nikkor 18-55 mm (Nikon Corp., Japan) placed on a slide bar. The pair of images was processed using Callipyan 3D or Anabuilder software (Ana builder, France) that transforms the two different images of the same structure with the intrapupillary distance proportion into one anaglyphic image.

RESULTS

During knee dissection, pictures were taken and transformed into three-dimensional images that become more realistic with the use of special glasses. The images were made during the dissection of the three layers of the posteromedial compartment of the knees.

CONCLUSIONS

Posteromedial corner ligament structures are quite complex and are not always clearly described in the literature. Three-dimensional images of these structures can help better understanding its anatomy.
