The mechanical effects of suture anchor insertion angle for rotator cuff repair.


Twelve matched pairs of humerii were instrumented with suture anchor at 90 degrees, 75 degrees, 45 degrees, and 30 degrees relative to the cortical border at the junction of the greater tuberosity and articular surface. Two fixtures were inserted into each specimen at different angles and loaded to failure. Suture anchors failed at an average of 171, 219… (More)
