Abstract
The Calaxo ® screw, developed by Smith and Nephew, is a novel biomedical composite composed of poly-DL-lactide-co-glycolide (PLLA:PGA) 85:15 and calcium carbonate particulates. Comparisons to an identical surgical anchor composed of PLLA, largely considered an industry standard, shows increased mean failure strength in surgical reconstructions of the patellar-tibia complex in sheep. SEM imaging confirms the osteoconductivity of the Calaxo ® screw proposed in previous studies and also suggest a positive effect on the differentiation of tissues along the tendon-bone interface. These findings support the intended use of the Calaxo ® screw as a fixation device for rotator cuff repair procedures.
