Available in a variety of size options with a choice of suture configurations, Twinfix Ultra suture anchors can be used for primary or double row repairs and for the medial row of a suture bridging technique. Non-absorbable - our non-absorbable PK suture anchor incorporates Peek-Optima polymer from Invibio. With a modulus similar to cortical bone, Peek-Optima exhibits an ideal combination of strength, biocompatibility, revisability and inherent radiolucent characteristics.
