✦ Synopsis

In this article, the design and properties of a new bioabsorbable suture anchor (SmartAnchor ™ ) are described and its properties are compared with those of some commercial anchors. Two comparative experiments were carried out in order to measure (1) the breaking force of suture/anchor attachment for SmartAnchor, MitekGII, and for Ogden anchors; and (2) the fixation force of the following anchors and tacks: SmartAnchor, Mitek-GII, BankartTack, and Suretac. The average suture/anchor attachment breaking force of SmartAnchor (204, 9 N) was 32% higher in comparison to MitekGII (155, 6 N) and 84% higher in comparison to the Ogden anchor (111, 4). The mean fixation force of the SmartAnchor (195, 5 N) was 40% higher than that of MitekGII (139, 2 N), but the T-test showed no statistical differences between MitekGII and SmartAnchor (p ‫؍‬ 0.05). Both tested tacks behaved very similarly in this test. The average fixation force (pull-out force) for both tacks was about 210 N. Therefore, it is evident that the bioabsorbable SmartAnchor has a high enough initial mechanical performance for clinical investigation.
