Summary

Single-center pilot prospective observational study to determine feasibility of assessing meniscal tissue vascularity using dynamic contrast-enhanced fluorescence arthroscopy

Detailed description

The purpose of this pilot study is to determine whether it is possible to translate the dynamic contrast-enhanced fluorescence imaging methods we have been using to assess bone perfusion in orthopaedic trauma patients to the field of arthroscopic surgery. In other words, it is the development of dynamic contrast-enhanced fluorescence arthroscopy. While fluorescence arthroscopes are available, there are several challenges associated with minimally invasive procedures compared with wide field imaging, and this pilot study will help determine whether these can be overcome. They are mainly to do with motion artifacts caused by the non-fixed position of the scope during wash-in/wash-out of the dye, and the use of an arthroscopic pump to pressurize the fluid in the surgical cavity. The long-term goal of this work is to use dynamic contrast-enhanced fluorescence arthroscopy for the assessment of vascularity of meniscal tissue arthroscopically to determine potential healing capacity using dynamic contrast-enhanced fluorescence imaging.
