Publication number: 20170303913Abstract: Surgical constructs and methods are provided for securing soft tissue to bone. One exemplary embodiment of a construct is formed from a suture filament and includes two terminal ends of filament and an intermediate portion disposed along at least a portion of a length extending between the terminal ends. The construct can have a first terminal end that is the first terminal end of the filament, and a second terminal end that includes a loop. The loop can be formed by disposing the second terminal end of the filament within a volume of a portion of the intermediate portion of the filament. In some disclosed methods, both terminal ends of the filament can be passed through tissue when performing soft tissue repairs. Various other embodiments of constructs and methods are provided, including constructs having two or more filaments associated with an anchor and methods of using such constructs.Type: ApplicationFiled: July 12, 2017Publication date: October 26, 2017Inventors: Mehmet Ziya Sengun, Howard C.
