Video Summary

This study compared construct stability and tendon lengthening remodeling after biceps tenodesis using arthroscopic suprapectoral versus mini open subpectoral techniques, both employing the same fixation system. Thirty patients per group were followed with tantalum bead radiographs at 1 and 12 weeks post-op. Results showed no significant differences between techniques in bead migration or clinical outcomes; no Popeye deformities were observed. Both groups demonstrated significant tendon lengthening and remodeling, with most elongation occurring within the first 4 weeks, suggesting tendon remodeling occurs regardless of fixation location without affecting function. Further research will compare other fixation methods.
