Systems and methods for soft tissue to bone repairs, without knot tying. The soft tissue repair systems include self-cinching constructs with a fixation device, a flexible strand and a shuttle/pull device attached to the flexible strand and provided within the body of the fixation device. A splice is formed by pulling on the shuttle/pull device subsequent to the fixation device being secured into the bone, to allow desired tensioning of soft tissue to be fixated or repaired relative to the bone.
