Purpose

The purpose of the study is to accumulate efficacy data on VisionScope Imaging (VSI) for pre-operative diagnosis of certain knee injuries (meniscal and articular cartilage injuries). The study will compare VSI's accuracy to MRI's in diagnosing the same injuries.

The hypothesis is the VisionScope Imaging system will be able to provide direct visualization and diagnostic images of inside the joint capsule space without fluid distention in the knee. This study will provide valuable feedback on the ability of the VisionScope system to provide physicians with the information they need to make a definitive diagnosis.
