Distal Biceps Brachii Tendon (DBBT) rupture is a relatively rare injury. Nonsurgical treatment determines 30-40% power loss of elbow flexion and up to 50% of forearm supination. Therefore, re-fixation of the DBBT is recommended. DBBT is exposed to tension and compression loading. It is known that tendon under compression might develop fibrocartilaginous metaplasia that improves the resistance to compression but reduces the resistance to tension. To test this hypothesis, the present study evaluated the presence of cartilage in DBBT samples. Furthermore, the present study evaluated the clinical and functional outcomes of anatomic reinsertion through suture anchors in a cohort of patients after 1, 3 and 5 years of follow-up.
