Brief Summary

Rotator cuff re-tear is a common delayed complication of arthroscopic rotator cuff repair. This process of re-tear is multifactorial and there has not been any readily identifiable perioperative measure that is predictive of subsequent rotator cuff failure. There have been no human studies looking at intraoperative assessment of rotator cuff vascularity, nor the predictive value that vascularity may have for rotator cuff re-tear. Indocyanine Green (ICG) has been safely used in patients for visualization purposes and has real potential for identifying vascularity in arthroscopic surgical patients. The aim of this study is to establish a standard dosing protocol for ICG in the arthroscopic visualization of rotator cuff vascularity.

Outcome Measures

Primary Outcomes (1)

  • Optimal dosing of an intravenous fluorescence solution (ICG) for arthroscopic evaluation of rotator cuff vascularity

    Advanced Imaging Modality (AIM) arthroscopy videos for each dosing arm will be collected and five signal intensity readings will be collected from the rotator cuff within each video. The ability to visualize rotator cuff vascularity will be graded by surgeons blinded to the ICG dosing using a 5 point Likert scale where 1 indicates worst visibility and 5 indicates best visibility. Post-hoc ANOVA analysis of surgeons' responses to determine what dose of ICG is optimal for the surgery.

    up to 6 months post operative visit

Study Arms (3)

Group 1:ICG 7.5 mg

EXPERIMENTAL

Subjects in this group are randomized to receive 7.5 mg dose of Indocyanine Green (ICG) intravenously during the clinical surgery. ICG is a substance that binds to proteins in the blood and allows surgery teams to view blood vessels with greater precision.

Drug: Indocyanine Green

Group 2:ICG 12.5 mg

EXPERIMENTAL

Subjects in this group are randomized to receive 12.5 mg dose of Indocyanine Green (ICG) intravenously during the clinical surgery. ICG is a substance that binds to proteins in the blood and allows surgery teams to view blood vessels with greater precision.

Drug: Indocyanine Green

Group 3: ICG 25 mg

EXPERIMENTAL

Subjects in this group are randomized to receive 25 mg dose of Indocyanine Green (ICG) intravenously during the clinical surgery. ICG is a substance that binds to proteins in the blood and allows surgery teams to view blood vessels with greater precision.

Drug: Indocyanine Green

Interventions

ICG is an injectable fluorescent pigment that binds to proteins in the blood and allows surgery teams to view blood vessels with greater precision. The ICG will not affect the course of the operative or postoperative period, and will be injected intravenously prior to the actual repair
