Table 1 Biomechanical analysis of the allogenic mineralized suture anchor (AMSA), the metallic suture anchor (MSA), and the bioabsorbable suture anchor (BSA) at the greater tuberosity of the humeral head

From: Biomechanical properties of a suture anchor system from human allogenic mineralized cortical bone matrix for rotator cuff repair

  AMSA (n = 18) MSA (n = 9) BSA (n = 9) p-value
Median load to failure (N) 248 (109–467) 204 (174–371) 197 (98–330) 0.427a
Median anchor displacement (mm) 1.5 (1–7) 2 (1–4) 1 (0–3) 0.193b
Failure mode (n)
 • Anchor breakage 0 (0%) 0 (0%) 2 (22.2%)  
 • Suture tear 0 (0%) 5 (55.6%) 2 (22.2%) < 0.001b
 • Maximum load to failure 18 (100%) 4 (44.4%) 5 (55.6%)
