Suture anchors made using PEEK-OPTIMATM polymers provide a strong, stable and highly versatile platform for optimal tissue-to-bone healing1,7.
The mechanical properties of PEEK-OPTIMA deliver several clinical benefits over metals, bioabsorbable and other biomaterials:
Tibial and femoral interference screw systems made from PEEK-OPTIMATM polymers provide many structural properties needed when designing the next generation fixation system:

Improved bone on-growth
PEEK anchors demonstrate improved bone on-growth in open construct anchors at months post-op CT when compared with biocomposite anchors8
Lower rates of osteolysis in rotator cuff repair
Studies show that anchors made with PEEK demonstrate significantly lower osteolysis than resorbable anchors9 in patients undergoing arthroscopic rotator cuff repair
Fully threaded and knotless PEEK soft tissue fixation
PEEK-OPTIMATM polymers offer bone ongrowth and strength as demanded by high-load implant applications, combined with artifact-free imaging10
Pre-contoured anatomic plates for hand, foot & ankle applications, cannulated implants for proximal interphalangeal fusions, and wedges for osteotomies are examples where PEEK-OPTIMA polymers can drive superior performance, including:
