A polymeric suture anchor for deployment in a preformed bone hole to secure soft tissue to bone in a knotless manner. The suture anchor comprises a hollow outer member and a hollow inner member longitudinally movable within the outer member. Suture is directed along a tortuous path distally through the lumens of both the inner and outer members, transversely across an eyelet situated at the distal end of the inner member and proximally through the lumens of both the inner and outer members. A suture-locking mechanism is provided along the tortuous path to crimp the suture by placing the anchor in a suture locked configuration. This is accomplished by moving the inner member proximally relative to the outer member in order to engage the suture-locking mechanism. The anchor is maintained in this configuration by the engagement of interlocking surfaces on the inner and outer members. Simultaneously, the inner member is provided with radially outwardly extending prongs which pass through slots in the outer member in order to engage bone surrounding the bone hole.
