Through clinical research Dr. Seneviratne has pioneered several procedures of the shoulder and knee. One such procedure is the endoscopic assisted subpectoral biceps tenodesis. This procedure used to be performed in an open manner with a large incision to attach the long head of the biceps tendon to the humerus bone under the pectoralis tendon. While the results of this procedure were excellent, the morbidity of the operation meant a lengthy recovery period. Through meticulous dissection studies Dr. Seneviratne has pioneered performing this same operation with a 7mm incision with the use of the endoscope. The result is alow morbity, rapid recovery procedure used to treat problems of the biceps tendon and labrum.

Dr. Seneviratne is deeply committed to the education of the next generation of orthopedic surgeons. He is a faculty member of the Mount Sinai Orthopedic Residency program educating young surgeons.
