Abstract
An innovative bone anchor and methods for securing connective tissue, such as tendons, to bone, which permit a suture attachment that ties entirely beneath the cortical bone surface. Advantageously, the suturing material between the connective tissue and the bone anchor is secured without the need for tying a knot. The suture attachment to the bone anchor involves the looping of a length of suturing material around a self-locking wedge block in the anchor, thereby avoiding an eyelet connection which requires a knot and which concentrates stress on a very small portion of the suturing material. Thus, failure rates are greatly decreased over conventional techniques, and the innovative procedures are significantly easier to perform than conventional techniques.
