Shoulder Arthroscopy

Knotless suture anchors made using Invibio biomaterials provide a strong, stable and reliable platform for optimal tissue-to-bone healing.

PEEK-OPTIMATM Natural features mechanical properties that allow reliable arthroscopy applications such as suture retention for knotless suture anchors. Commonly used in the lateral row of a double-row rotator cuff or in the Glenoid for SLAP and Bankart repairs, knotless suture anchors offer surgeons time efficiency in the OR to perform procedures faster and reduce the time patients are under anesthesia.

A recent study1 focused on analyzing the osseous reaction after arthroscopic double-row rotator cuff repair using bio-absorbable poly-L-lactic acid (PLLA) and non-absorbable polyetheretherketone (PEEK) suture anchors, showed that both materials lead to osseous reaction, whereas consequences of pronounced fluid in Poly-L-lactic acid (PLLA) patients remain unclear. Pronounced tunnel widening in lateral anchors leads to the assumption that other causes such as mechanical stress potentially have to be considered when analyzing osseous reaction.

Although the safety and efficacy of bioabsorbable anchors has been well documented, there are numerous reports regarding the early failure related to bioabsorbable implant breakage or premature degradation. Glenohumeral synovitis, glenoid osteolysis, loose bodies, and chondral injury are some of the notable complications that have been reported. Newer materials, such as polyetheretherketone PEEK and other composites, may address concerns of biocompatibility and material strength.2 Biocomposite interference screws or suture anchors composed of Poly(Lactide-co-Glycolide)/β-Tricalcium Phosphate (PLGA/β-TCP) almost fully absorb over 3 years while promoting osteoconductivity with few reported adverse events.3

An optimized design for carbon fiber reinforced polyetheretherketone (CFR-PEEK) suture anchors offers the advantages of radiolucency, and mechanical properties similar to bone with the ability to self-tap. This may have positive implications for reducing surgery times and the associated costs with the procedure.4

Anchors made of PEEK-OPTIMATM polymer offer:

  • Superior material for high-strength anchors: the natural mechanical strength of PEEK-OPTIMATM polymers has shown remarkable performance in load-to failure strength5.
  • No artifacts for X-ray, CT, and MRI , allow for simple post-operative implant assessment.
  • Bio-inert to reduce the possible risk of patient reaction.
