The EndoButton technique of distal biceps tendon repair provides strong biomechanical fixation. This strength of fixation may allow earlier postoperative range of motion (ROM). A retrospective review of 15 male patients undergoing single incision EndoButton repairs was used. Six subjects participated in conventional supervised postoperative rehabilitation while nine subjects were allowed unrestricted ROM after 2 weeks. Final ROM, time to full ROM, and Disabilities of Arm Shoulder and Hand (DASH) scores were compared. There was a significant difference for time to full ROM (p<0.05). The mean time to full ROM was 8.67 weeks for the supervised therapy group and 4.38 weeks for the unrestricted group. There were no reruptures in either group. There were no significant differences in final ROM or DASH scores. These data suggest that unrestricted ROM results in a quicker return to full ROM without an increased risk of rerupture.
