Distal biceps tendon repair via new knotless endobutton fixation: A biomechanical study.

ABSTRACT:

Background

Distal biceps tendon repair using endobutton fixation has shown the best biomechanical results in terms of pullout strength. Here, we compared Sethi's enhanced tension adjustable endobutton technique known as the "tension slide technique" to a new knotless endobutton fixation technique without a post-fixation screw. Our new approach is as effective as the tension slide technique in terms of pullout strength and gapping after early mobilization.

Methods

A biomechanical cadaveric study with 16 paired arms was performed. With the radius held in place, the distal biceps tendon was loaded at 100 N for 500 cycles and the load was then increased until failure. Gapping after loading cycles and maximum load to failure were recorded and compared.
