A Biomechanical Analysis of Capsular Plication Versus Anchor Repair of the Shoulder: Can the Labrum Be Used as a Suture Anchor?

A multiphase biomechanical study was performed using human tibialis anterior tendons and cuboid bones, comparing the fixation of the tendon to the bone using bone anchors and bone tunnels. Twenty-six specimens were tested for ultimate load to failure comparing Mitek Superanchor fixation with no. 1 and no. 5 braided polyethelyne suture to bone tunnel fixation. Mitek Superanchor with no. 5 suture failed at 223 N, compared with Mitek Superanchor with no. 1 suture at 134 N and bone tunnel at 143 N ( P = 0.033). Mitek with no. 1 suture versus bone tunnel was not significantly different. The Mitek with no. 5 suture failed at the tendon/suture interface (75%), the Mitek with no. 1 suture failed at the suture/anchor interface (56%), and bone tunnel fixation failed most commonly by fracture of the tunnel (76%). This study is the first biomechanical analysis of the pullout strengths of bone tunnels or suture anchors in the cuboid bone. We have shown that the suture anchor has a pullout strength comparable or superior to a conventional bone tunnel in an in vitro situation. We believe it is a viable alternative to fixation of the tibialis anterior tendon to the cuboid when there is insufficient tendon length or failure of the bone tunnel.

Repair Techniques

Background Various methods are available for repair of meniscal tears: a biodegradable meniscal implant without sutures (Biofix meniscus arrow), a suture anchor device (T-fix), and horizontal and vertical mattress sutures. Hypothesis There is no difference in repair strength or mode of failure among the techniques compared. Study Design Controlled laboratory study. Methods Reproducible tears were created in bovine menisci and repaired with each of the techniques. Residual displacement of the tear immediately after repair and the resistance to displacement under load applied perpendicular to the tear were measured and compared. Results The residual displacement after repair was highest in the Biofix arrow group (0.70 mm) and lowest in the vertical mattress suture group (0.21 mm). The ultimate strength of repair was strongest for the vertical sutures (202 ± 7 N) and lowest for the arrow and T-fix (95.9 ± 8 N and 99.4 ± 8 N, respectively). The force required to generate 2 mm of tear displacement was greatest for the vertical sutures (143 N) and least for the arrow (43.6 N). Conclusions Suture techniques were stronger at all levels of testing. Clinical Relevance Knowledge of biomechanical characteristics aids the surgeon in choosing the appropriate technique for each situation.
