KNOTLESS SUTURE ANCHOR FOR SOFT TISSUE REPAIR AND METHOD OF USE

摘要

KNOTLESS SUTURE ANCHOR FOR SOFT TISSUE REPAIR AND METHOD OF USE A knotless suture anchor provides a method for securing soft tissue to a rigid structure such as bone. The anchor has an inner member that receives suture thread and rotates within an outer tubular member. As the inner member rotates, the suture thread is wrapped onto the inner member thereby increasing contact with the outer tubular member which applies pressure to the wrapped suture thread to retain it in position on the inner member while simultaneously and adjustably tensioning the suture thread. One or more suture guides and suture guiding channels are positioned on the outer tubular member and configured to restrict contact of an at least one suture thread with the bone. A ratchet prevents undesirable counter-rotation, although the ratchet can be released to permit loosening of the suture thread. Also described is a suture bridge and suture platform for providing further stabilization of a tendon.
