A medical implement particularly useful in arthroscopic sutures, includes: a handle having a proximal end configured for manual gripping by a user, a distal end, an internal passageway extending between the proximal end and the distal end, and an intermediate portion formed with a recess extending from the outer surface to the internal passageway. A shuttle is movable through the passageway and has an intermediate portion exposed within the recess for manipulation by a user gripping the handle, and a suture-receiving-element at its distal movable axially through the distal end of the handle. A roller is rotatably mounted to the handle to underlie the exposed portion of the shuttle such that, after a suture has been received by the suture-receiving-element of the shuttle, a user, gripping the handle, may manipulate the shuttle with respect to the distal end of the handle by thumb-pressing the exposed portion of the shuttle against the roller and rotating the roller.
