A method of providing ligamentory like support between two spaced locations inthe body of a patient comprising fixing an anchor in each location, connectingthe anchors by a filamentary element, adjusting the tension of the filamentaryelement between the locations to establish the desired spatial relationshipbetween the locations to provide at least a supplementary ligamentory supportbetween the locations. The anchor (115) comprising a base (153), a head (157)having a configuration to facilitate insertion of the head into tissue andretention of the head in the tissue once inserted, the base formed with anaperture (161) adapted to receive a length of a filamentary element (127) andpermit slidable movement of the filamentary element through the aperture inone direction but to restrict movement of the filamentary element through theaperture in the opposite direction. A holder (189) to support the anchor toeffect is fixation into the tissue and an insertion appliance (173) to supportthe holder and be used in applying the anchor to the tissue
