Arthroscopic Rotator Cuff Repair Using Transosseous Suture-Needle System. Principle investigator. Goals of this project are to develop and research this transosseous rotator cuff repair system. Research includes basic science studies (anatomical, technical, and biomechanical) and clinical outcome studies to evaluate the safety and effectiveness. Currently, performing technical pilot studies on cadaver specimens.

The Prospective Evaluation of Arthroscopic Rotator Cuff Repair using Suture Anchors and Intra-Articular Knot Tying Techniques for Patients with Full Thickness Rotator Cuff Tears. Co-investigator. Goal is to obtain prospective outcome data for a large group patients undergoing arthroscopic rotator cuff repair. Collected 350 + patients and are collecting data for the two-year follow up (2-, 5-, and 10-year follow up). Funding level: $500,000 +.
