Long head of biceps tenotomy and tenodesis don’t affect elbow flexion and forearm supination strength

摘要

Background: Lesions of long head of biceps tendon (LHBT) are often seen in patients with rotator cuff tears, for which tenotomy and tenodesis of the LHBT are frequently performed. Although the good clinical results of tenotomy and tenodesis in simultaneous arthroscopic rotator cuff repair (ARCR) were reported, weakness of elbow flexion and forearm supination strength are also predictable. The purpose of this study is to compare the postoperative outcome and the muscle strength of elbow flexion and forearm supination after ARCR between cases with LHBT tenotomy, tenodesis and preserved.
