Evolution of Suture Anchor

Suture anchors are the technology of choice when performing labral repair. A variety of suture anchor types exist, each with their own benefits and limitations. Suture anchors contain three components: the anchor, the eyelet and the suture. The anchor can be a screw mechanism, or an interference fit.

Materials used for anchors include various metals or bioabsorbable composites. The eyelet is a loop in the anchor through which the suture passes. Finally, the suture is what connects the under-repair tissue to the anchor. Suture can be absorbable or permanent, and varies in strength and elasticity. The ideal anchor when performing a labral repair is low profile, to eliminate the possibility of the anchor violating the glenoid cartilage, and provides excellent pullout strength.
