The Effect of Trabecular Microstructure and Mechanical Properties on the Pullout Strength of Suture Anchors

Suture anchors are a type of bone anchor designed to attach soft tissues, such as tendons and ligaments, to bone. Suture anchors are commonly used for soft tissue repairs including rotator cuff repairs, bicep tenodesis, flexor tendon repairs, and patellar tendon ruptures among others. In 2007, over 1 million suture anchors were used in 460,000 shoulder repairs in the US alone[1].
