A knotless returning and locking system for bone fracture stabilization and soft tissue repair and reinforcement, comprising: a returning and locking anchor (400, 500) having a body (402, 502) with a proximal end (404, 504), a distal end (406, 506), and defining a longitudinal axis (408, 508), the body (402, 502) forming an internal passage (441, 541) and a return feature (413, 513), the internal passage (441, 541) having a threaded receiver (430, 530) located at the proximal end (404, 504) of the body (402, 502) and including a proximal portion, a mid portion, and a distal portion, the return feature (413, 513) located distal to the threaded receiver (430, 530) and in communication with the internal passage (441, 541); and a threaded set screw (416, 516) having a proximal portion, a mid portion, and a distal portion, characterized in that the threaded set screw (416, 516) is configured for rotational insertion into the threaded receiver (430, 530) to achieve a progressively increasing interference fit about a flexible synthetic strand (418, 518) passing between the proximal portions and the mid portions of the threaded receiver (430, 530) and the threaded set screw (416, 516) and a progressively decreasing interference fit about the flexible synthetic strand (418, 518) passing between the mid portions and the distal portions of the threaded receiver (430, 530) and the threaded set screw (416, 516), wherein the progressively increasing interference fit and the progressively decreasing interference fit combine to provide a locking feature that reversibly secures the flexible synthetic strand (418, 518) in relation to the returning and locking anchor (400, 500). a returning and locking anchor (400, 500) having a body (402, 502) with a proximal end (404, 504), a distal end (406, 506), and defining a longitudinal axis (408, 508), the body (402, 502) forming an internal passage (441, 541) and a return feature (413, 513), the internal passage (441, 541) having a threaded receiver (430, 530) located at the proximal end (404, 504) of the body (402, 502) and including a proximal portion, a mid portion, and a distal portion, the return feature (413, 513) located distal to the threaded receiver (430, 530) and in communication with the internal passage (441, 541); and a threaded set screw (416, 516) having a proximal portion, a mid portion, and a distal portion, characterized in that the threaded set screw (416, 516) is configured for rotational insertion into the threaded receiver (430, 530) to achieve a progressively increasing interference fit about a flexible synthetic strand (418, 518) passing between the proximal portions and the mid portions of the threaded receiver (430, 530) and the threaded set screw (416, 516) and a progressively decreasing interference fit about the flexible synthetic strand (418, 518) passing between the mid portions and the distal portions of the threaded receiver (430, 530) and the threaded set screw (416, 516), wherein the progressively increasing interference fit and the progressively decreasing interference fit combine to provide a locking feature that reversibly secures the flexible synthetic strand (418, 518) in relation to the returning and locking anchor (400, 500).
