Rotator cuff tears are common musculoskeletal conditions that are often degenerative and typically affect older adults. They may or may not be symptomatic, and their prevalence increases significantly with age, from approximately 9.7% in individuals under 20 years to 62% in those over 80 years. The rotator cuff plays a critical role in stabilizing the shoulder joint through the concavity-compression mechanism, and its dysfunction can result in shoulder instability, pain, and reduced upper limb strength. Conservative management, including physical therapy, therapeutic modalities, and medications, is considered the first-line approach for treating Rotator cuff tears , while surgical intervention is reserved for cases unresponsive to conservative treatment. Among the commonly performed surgical procedures, biceps tenotomy and biceps tenodesis are often combined with rotator cuff repair to alleviate pain and improve functional outcomes. Hand grip strength is widely recognized as a reliable indicator of overall upper limb function and may be affected by both the pathology and its surgical management. Despite its clinical relevance, limited studies have directly compared the impact of Biceps tenotomy and Biceps tenodesis on Hand grip strength. Furthermore, these surgical techniques may influence other functional outcomes, including elbow flexion strength, forearm supination strength, and pain perception. Therefore, this study seeks to investigate and compare the effects of Biceps tenotomy versus Biceps tenodesis on these parameters in patients undergoing surgical repair for rotator cuff tears.
