摘要：

Five commercially available suture anchor devices were tested to failure in human cadaveric proximal tibiae. A total of 198 trials were completed. Insertion was uncomplicated for all anchors, with the exception of the Acufex Rod TAG device. with five of 22 (23%) of these breaking upon insertion into thicker cortical bone. Overall, the anchors performed significantly (p < 0.05) better when placed in thicker cortical bone, further away from the joint surface, and when loaded in a direction parallel to the bone surface. The Mitek GII anchor failed (pulled out of bone) less often than the other anchors (19% vs. 46%). In loading perpendicular to the bone surface, the Mitek GII and Statak were the strongest (p < 0.05), with mean loads at failure of 82.5 and 90.2 N, respectively. The Acufex Rod TAG, Acufex Wedge TAG, and Mitek GI failed at 67.2, 65.5, and 49.4 N respectively.
