High-Tensile Strength Tapes Show Greater Ultimate Failure Load and Less Stiffness Than High-Tensile Strength Sutures in a Subpectoral Biceps Tenodesis Porcine Model.

ABSTRACT:

Purpose

To compare the biomechanical properties of high-tensile strength tape and a high-tensile strength suture in subpectoral biceps tenodesis using a suture anchor in a porcine tendon model.

Methods

A total of 24 artificial composite (polymer and glass fiber) humeri and porcine flexor profundus tendons were used. Two types of suture materials, high-tensile strength sutures (group S) and high-tensile strength tapes (group T), were evaluated. After we inserted metallic suture anchors with either 2 sutures or tapes 5 cm from the superomedial corner of the greater tuberosity, a Krackow suture technique was used to secure the tendons. After a preload of 5 N for 2 minutes, a cyclic loading test from 5 to 70 N was conducted for 500 cycles. Finally, the specimen was loaded to failure at a rate of 1 mm/s.

Results

There were no significant between-group differences in elongation after cyclic loading and elongation at failure load for group S and group T (P = .977 and .630, respectively). The ultimate failure loads in group T (278.2 ± 54 N) were significantly greater than those in group S (249.4 ± 32 N) (P = .028). In contrast, the stiffness values in group T (28.5 ± 4.0 N/mm) were significantly lower than those in group S (32.3 ± 4.5 N) (P = .028). Ten specimens in group S and 8 specimens in group T failed, with tendons being cut through by the sutures, whereas the other 2 specimens in group S and 4 specimens in group T failed due to suture breakage.

Conclusions

Using high-tensile strength tapes in subpectoral biceps tenodesis using a suture anchor leads to significantly greater ultimate failure load as compared with using high-tensile strength sutures in a porcine model. Although lower levels of stiffness were found in high-tensile strength tape group, the difference in the means were not large between 2 groups.

Clinical relevance

A strong suture-tendon structure may prevent clinical failure of a subpectoral biceps tenodesis using a suture anchor.

Project description:Purpose To determine whether an association exists between the presence of cervical spine pathology and postoperative patient-reported outcomes (PROs) in patients undergoing open subpectoral biceps tenodesis (BT). Methods A retrospective review of patients undergoing isolated BT from August 2011 to May 2019 was conducted. Cases were defined as patients with concomitant cervical spine disease (disc disease, disc herniations, neuroforaminal/central stenosis). Controls were patients without cervical spine disease. Postoperative PROs were collected from all patients with a minimum of 12-month follow-up. Cases and controls were matched 1:1 using age and body mass index. PROs were compared using the χ2 text, Fisher exact test, or analysis of variance. Results A total of 23 cases and 23 controls were identified. Cases and controls had similar distributions of age (42.4 ± 4.4 years, 40.4 ± 4.5, P = .15), sex (83% male, 87% male, P = .68), body mass index (28.0 ± 4.0, 27.6 ± 4.3, P = .78), and percentage of athletes (65% athlete, 61% athlete. P = .76). All cases had evidence of neuroforaminal stenosis and multilevel degenerative disc disease, whereas 19 of 23 (83%) had evidence of central canal stenosis. Cases had a greater visual analog scale (VAS) score during Sport score (3.6 ± 0.7 vs 1.2 ± 0.6, P = .013) and lower Subjective Shoulder Value (69.5 ± 5.8 vs 84.1 ± 5.4, P = .070) and Shoulder Instability-Return to Sport after Injury score (60.4 ± 5.8 vs 77.4 ± 6.0, P = .046). There were no significant differences between groups’ ASES, baseline VAS, overall satisfaction scores, and willingness to undergo the same operation again. No significant differences were found in postoperative rate of return to sport, time to return, and return to preoperative competitiveness. Conclusions Patients with SLAP tears undergoing isolated BT in the presence of cervical spinal stenosis may have inferior Subjective Shoulder Value, Shoulder Instability-Return to Sport after Injury, and VAS during sport scores as compared with controls, although many PROs were similar at follow-up. Athletes undergoing BT, particularly with concomitant cervical spine pathology, should be counseled appropriately before surgery. Level of Evidence Level III, case–control study.
