1. A suture anchor comprising:
- an elongated shaft having an exterior sidewall extending between a proximal end and an opposing distal end;
a helical first thread wound about and outwardly projecting from the exterior sidewall of the shaft so as to extend between the proximal end and the distal end of the shaft, the first thread having a helical proximal face and helical distal face; and
a first suture port transversely extending through at least a portion of the first thread at the proximal end of the shaft, the first suture port being orientated such that the first suture port extends at least from toward the helical proximal face to toward the helical distal face.

Abstract
A suture anchor includes an elongated shaft having an exterior sidewall extending between a proximal end and an opposing distal end. A helical first thread is wound about and outwardly projects from the exterior sidewall of the shaft so as to extend between the proximal end and the distal end of the shaft. A first suture port transversely extends through at least a portion of the first thread at the proximal end of the shaft. The suture port is configured to receive a suture line.
